Abstract According to previous studies on the pyrolysis of vegetable oils, it resulted that the thermal cracking process is prone to produce large yields of ethylene, propylene, hydrogen and methane, comparable with the gas proceeding from the steam cracking of naphtha, but at much lower process temperature, this ensuring important energy savings. The studies are performed on very different raw materials and different reaction conditions, that being why at this moment it is very difficult to predict the products yield. This paper uses an analytical semiempirical model (ASEM) developed at the University of Florida, by applying it to a different raw material. The ASEM model fits very well to our experimental data, obtained at higher temperature but some parameters have to be adjusted. In the end we confirm a set of systemic parameters to be used for the prediction of main products yield proceeding from vegetable oil in an extended range of temperatures.

The employment of used vegetable oils (UVOs) as raw materials in key sectors as energy production or bio-lubricant synthesis represents one of the most relevant priorities in the European Union (EU) normative context. In many countries, the development of new production processes based on the circular economy model, as well as the definition of future energy and production targets, involve the utilization of wastes as raw material. In this context, the main currently applied EU regulations are presented and discussed. As in the EU, the general legislative process consists of the definition in each State Member of specific legislation, which transposes the EU indications. Two relevant countries are herein considered: Italy and Spain. Through the analysis of the conditions required in both countries for UVOs’ collection, disposal, storage, and recycling, a wide panorama of the current situation is provided.

Spatial Inhomogeneities

Fossil materials are widely used raw materials in polymerization processes; hence, in many cases, the primary goal of green and sustainable technologies is to replace them with renewables. An exciting and promising technology from this aspect is the isocyanate-free polyurethane production using vegetable oil as a raw material. Functional compounds can be formed by the epoxidation of vegetable oils in three reaction steps: epoxidation, carbonation, and aminolysis. In the case of vegetable oil carbonation, the material properties vary strongly, with the composition affecting the solubility of CO2 in the reaction mixture. Many attempts have been made to model these interactions, but they generally do not account for the changes in the material properties in terms of spatial coordinates. A 2D CFD model based on the combination of the k-ε turbulence model and component mass balances considering the spatial inhomogeneities on the performance of the reactor was created. After the evaluation of the mesh independence study, the simulator was used to calculate the carbonation reaction in a transient analysis with spatial coordinate-dependent density and viscosity changes. The model parameters (height-dependent mass transfer parameters and boundary flux parameters) were identified based on one physical experiment, and a set of 15 experiments were used for model validation. With the validated model, the optimal operating temperature, pressure, and catalyst concentration was proposed.

Abstract The main raw material of paper and cardboard used in packaging is cellulose. Cardboard packages made of cardboard, which can be produced in much different quality and weight, are obtained in numerous shapes and appearances 1, 2 . Paper and cardboard packaging are among the most economical packaging types. Using less raw materials, more durable but thin, light, economical cardboard is produced 2, 3 . In this study, under equal printing conditions, test prints were made on cardboard substrates (for cardboard packaging) with mineral oil based, vegetable oil (soy oil) based and UV cured inks used for the printing of the same images. After these prints, the properties of mineral oil, vegetable oil and UV ink; the effect on the print results was measured from different ways (Chroma*, Print density, unprinted surface Gloss 75°, Print Gloss 60°). At the same time, the visual differences between the print results were determined by the optical imaging (SEM) method and were examined by the elemental analysis method.

The common food container product was made from plastic such as polypropylene, polystyrene, etc which has slowed to degrade hence affected to the environmental pollution and health disorder. Therefore, environmentally friendly food container composite is developed from sustainable resources such as sorghum bagasse and citric acid. The effects of sorghum species, sorghum particles and citric acid content on the composite properties were investigated. Local species of sorghum was used as raw material such as Super 2 in the manufacturing of food packaging.  The size and moisture content of the particles were passthrough on 40 mesh and 10%, respectively. The content of the particle was variated such as 10, 15, and 20% wt. Furthermore, citric acid was used as a binder with difference content such as 10, 20, and 30% wt.  Those raw materials were mixed with tapioca starch, polyvinyl alcohol (PVA), and glutaraldehyde. The mixing material was hot pressed at 180 ℃ for 15 minutes. The composite dimension was 12 cm x 10 cm x 3 mm. The physical and mechanical properties of the composite were carried out. Considering the properties of the composite, sorghum bagasse and citric acid are suitable as raw material of food container composite.

Background. In recent years, requirements for the properties of lubricants and their components are increasing. Attention is paid to the impact of lubricants on the environment. Urea greases fully meet the high requirements for the properties of lubricants. The development of greases of this class and vegetable oil-based additives should solve the environmental problems of their use. Objective. The purpose of the paper is development of urea greases and their components using raw materials of plant origin. Methods. A number of protective additives to lubricants were obtained by epoxidation of vegetable oils and introduction of nitrogen-containing fragments on the carbonyl group and epoxy ring. Amidation of triacylglycerides of vegetable oils with ethylenediamine synthesized monoaminoamides of fatty acids of linear structure. Urea thixotropic systems are synthesized by the interaction of polyisocyanate with fatty acid monoaminoamides in petroleum oil. Synthesized additives in various quantities were introduced into the composition of the investigated products in order to check the operational properties of the finished greases. Results. The obtained greases are characterized by a high level of mechanical and colloidal stability. Their composition and chemical structure were established by a set of spectrometric methods of analysis. The upper temperature limit of application of the synthesized urea in the range of 150–200 °С is established by the method of derivatographic analysis. It is established that the combination of urea thickener and vegetable oil-based additives allows obtaining urea greases with high thermal stability, improved protective and antioxidant characteristics. The use of environmentally friendly oleochemical products in the composition of the thickener and lubricant additives improves the biodegradability of the developed grease composition. Conclusions. It is shown that the proposed series of vegetable oil transformations allows obtaining ready-made compositions of urea greases and their components using raw materials of natural origin. The obtained products have satisfactory operational properties and according to some indicators industrial analogues prevail. This allows us to recommend the developed urea oils as substitutes for commercial products.

Biogas is one alternative to replace the irreplaceable energy source that has begun to diminish its existence. The raw materials for biogas manufacture are renewable biomass, usually using plantation waste, agriculture, and livestock. Using biogas can also reduce environmental pollution. One of the agricultural waste that has great potential to become the raw material of biogas is teak sawdust. Wood processing industry in Indonesia quite a lot, but wood has a high lignosesluosa content, so it needs the right method to process it. With the delignification of lignin levels on teak sawdust will decrease. Wood sawdust is soaked using NaOH for 1, 2, 3, and 4 days with 4% w / v concentration. The lowest lignin and hemicellulose content was 25.79% and 87.9% in pretreatment for 4 days, while the highest cellulose level was 57, 34%. The accumulated volume of biogas at 1 day pretreatment, ie 709 ml / g TS. Gcms shows the enlarged peak area of methanamine, N-methyl from before pretreatment. The fastest biogas formation (λ) in 4 days pretreatment, 1.60403 days and the largest constant A and U variables at 1 day were 914.5903 ml / g TS and 34.59765 ml / g TS.

American Palm

The growing global demand for vegetable oils for food and for replacing fossil fuels leads to increased oilseeds production. Almost 122 of the current 187 million tons of vegetable oils produced in the world correspond to palm and soybean oils. The oil palm is cultivated in the tropical zone, in areas formerly occupied by forests, and soybean oil is a by-product of protein meal production. The diversification of raw materials for the vegetable oil market is thus strategic for both food and non-food sectors. Sources for vegetable oil should be economically competitive and provide sustainability indexes higher than that provided by oil palm and soybean. In this context, we describe the potential of Acrocomia aculeata, popularly known as macauba. Macauba is an American palm from the tropical zones which presents oil productivity and quality similar to that of the oil palm. It grows spontaneously in a wide range of environments and it is not very water demanding. Macauba palm has a high potential for oil production and for diversification of co-products with some potential of value aggregation. Such a perennial and sustainable species will probably fulfill the requirements to become an important new commercial oilseed crop.
