Waste cooking oil (WCO) has been considered a low-cost and renewable feedstock for the production of biodiesel and biobased products if it can be economically and efficiently collected and recycled. The objective of this case study is to review the scientific background of WCO recycling in the literature in connection with the regulatory and promotional measures in Taiwan under the authorization of a legal waste management system. Furthermore, the updated information about the on-line reporting WCO amounts in Taiwan is also analyzed to illustrate its significant increase in the recycling status of WCO officially designated as one of the mandatory recyclable wastes since 2015. Finally, an overview of available utilization of WCO as biodiesel, fuel oil, and non-fuel related uses is briefly addressed in this paper. It shows that the collected amounts of WCO from residential and commercial sectors in Taiwan significantly increased from 1599 tonnes in 2015 to 12,591 tonnes, reflecting on the WCO recycling regulation effective since 2015. Practically, the most important option for this urban mining is to reuse WCO as an energy source for the productions of biodiesel and auxiliary fuel. Other non-fuel related uses include the production of soaps/detergents, C-18 fatty acids, and lubricants. However, the reuse of WCO as a feed additive should be banned to prevent it from re-entering the food chain.

The article investigates the processes of preparing liquid fuel based on a mixture of coal from the Alai deposit (Kyrgyzstan) and water with the addition of other components, for combustion in various power plants and intended to replace organic fuels (solid fuel, fuel oil and gas). On the basis of the research results, a technological scheme for the preparation of coal-water fuel from the organic matter of the Alai deposit has been developed. Methods and technologies for the preparation of coal-water fuel are described. As a result, an efficient and energy-efficient method for producing coal-water fuel has been developed, which has a high energy potential, environmental friendliness, low cost, a wide range of applications and a fairly simple technology for its implementation.

This paper focuses on the physical property prediction of waste cooking oil biodiesel and examines the accuracy of different methods to estimate reliable basic physical properties, including density, viscosity and surface tension of waste cooking oil biodiesel in a wide range of temperature based on its fatty acid methyl ester component. A program for the physical property prediction of the biodiesel was developed and experimental measurements for the density, viscosity and surface tension of the biodiesel were performed to validate the chosen methods. The results show that the modified Rackett equation and the Orrick-Erbar method have the high estimation accuracy for the prediction of the density and the viscosity, respectively. The Sastri-Rao method and the Pizer method have the accuracy enough to predict the surface tension.

Neutrally Buoyant

ABSTRACT Electric utilities have been increasing their use of Group V fuel oils (known in the industry as low-API gravity fuel oils or LAPIO), because of their relatively low cost and high btu values. Group V fuel oils are defined as having an API gravity less than 10 at 60° F (thus a specific gravity ≤1.00 g/cm3). These oils have a wide range of densities and properties and thus cannot be characterized as a single product with a given set of properties and behavior. Group V fuel oils can float, be neutrally buoyant, sink, or all three, depending on their composition and the physical nature of the receiving waters (salinity, temperature, suspended sediment content). They can physically separate into fractions with different behavior. Three models are proposed for predicting the behavior of Group V fuel oil spills, based on observations at previous spills. If spilled directly into the water, heavier-than-water oil will form into drops and remain in suspension if there is any current. In no-current areas, sinking oil can accumulate on the bottom and be recovered. When mixed in the surf zone, the oil tends to pick up sand and sink, without ever stranding on shore. Special problems are associated with locating, containing, and recovering oil that is neutrally buoyant or on the bottom.

AbstractSustainable biodiesel production should: a) utilize low cost renewable feedstock; b) utilize energy-efficient, nonconventional heating and mixing techniques; c) increase net energy benefit of the process; and d) utilize renewable feedstock/energy sources where possible. In this paper, we discuss the merits of biodiesel production following these criteria supported by the experimental results obtained from the process optimization studies. Waste cooking oil, non-edible (low-cost) oils (Jatropha curcas and Camelina Sativa) and algae were used as feedstock for biodiesel process optimization. A comparison between conventional and non-conventional methods such as microwaves and ultrasound was reported. Finally, net energy scenarios for different biodiesel feedstock options and algae are presented.

Cooking Oil

Low cost, high fatty acid content waste cooking oil was transformed into biodiesel using an acid catalyzed chemical esterification reaction with 0.5 vol.% of H2SO4 at 60�C for 1 hour followed by the main transesterification reaction. For the purpose of comparison, biodiesel fuel was also prepared using straight vegetable oils (SVO�s). The gas chromatography test showed higher than 95% FAME (fatty acid methyl ester) content for different types of utilized feedstocks. Biodiesel fuel and its blends were characterized based on ASTM test methods to investigate its density, viscosity, flash point, pour point, heating value, and its cetane index and similar physical properties were obtained for all the prepared biodiesel fuels. B20 blend, which contains 20 vol.% of biodiesel and 80 vol.% of diesel, showed a better performance than B0 (100 vol.% of diesel) when tested in a laboratory compression ignition diesel engine. After simulation of the production process via Aspen Hysys, a feasibility study was conducted and the results revealed that utilizing waste cooking oils (WCO�s) as feedstock is more economical than starting with SVO�s as raw material.
