The agenda to utilize and efficiently convert biomass has been raised to alleviate environmental problems and pressure on the reliance on fossil fuel. Intermediate pyrolysis has the ability to treat different biomasses and coproduction of biooil and adsorption biochar. This review article aims to evaluate the appropriateness of intermediate pyrolysis for the coproduction of biooil and adsorption biochar. It was observed that coproduced biooil is of high quality, stable, and miscible that can be used directly to existing engines or be easily blended. The biochar coproduced is good for adsorption but is not stable for microbial attack and hence unsuitable in soil treatment but for hydrometallurgy. Since the process is capable of treating waste biomass, it is an opportunity for further investigations in areas where wastes are plenty and less utilized. To increase the effectiveness of this technology for coproduction, optimizing parameters, design of efficient reactors, and use of catalyst must be worked upon.

Increasing Temperature

The water hyacinth has high growth rates that can lead to various environmental problems and the production of large amounts of waste biomass. However, it can be a source of lignocellulosic biomass for the production of bio-oil. This study aims to determine the effect of temperature variation on the pyrolysis process of water hyacinth ex-situ with bentonite catalyst and the addition of water vapor. Temperature variations used are 450°C, 550°C, and 650°C. The pyrolysis process uses 300 grams of water hyacinth and is carried out for 1 hour. The results showed that increasing pyrolysis temperature reduced the char and bio-oil products, but increased the product of gas. Pyrolysis at 450°C produces a lot of bio-oil, while at the temperature of 650°C tends to produce gas products. Also, increasing the pyrolisis temperature results in a higher density of bio-oil. Gas chromatograph testing was carried out to determine the content of organic compounds found in bio-oil. Hydrocarbons are obtained which increase with increasing temperature. The highest percentage of the content of organic compounds is in oxygen compounds. Components of alcohol, phenols, ketones, aldehydes are functional compounds found in the content of bio-oil. Acid compounds are also contained in bio-oil from the results of pyrolysis of water hyacinth.

Transforming waste biomass materials into bio-oils in order to partially substitute petroleum asphalt can reduce environmental pollution and fossil energy consumption and has economic benefits. The characteristics of bio-oils and their utilization as additives of asphalts are the focus of this review. First, physicochemical properties of various bio-oils are characterized. Then, conventional, rheological, and chemical properties of bio-oil modified asphalt binders are synthetically reviewed, as well as road performance of bio-oil modified asphalt mixtures. Finally, performance optimization is discussed for bio-asphalt binders and mixtures. This review indicates that bio-oils are highly complex materials that contain various compounds. Moreover, bio-oils are source-depending materials for which its properties vary with different sources. Most bio-oils have a favorable stimulus upon the low temperature performance of asphalt binders and mixtures but exhibit a negative impact on their high-temperature performance. Moreover, a large amount of oxygen element, oxygen-comprising functional groups, and light components in plant-based bio-oils result in higher sensitivity to ageing of bio-oil modified asphalts. In order to increase the performance of bio-asphalts, most research has been limited to adding additive agents to bio-asphalts; therefore, more reasonable optimization methods need to be proposed. Furthermore, upcoming exploration is also needed to identify reasonable evaluation indicators of bio-oils, modification mechanisms of bio-asphalts, and long-term performance tracking in field applications of bio-asphalts during pavement service life.

AbstractConversion of spent coffee grounds through the Thermo-Catalytic Reforming system (TCR®) is evaluated in this study. While, the TCR® is a technology that has been developed by Fraunhofer UMSICHT, which combines an intermediate pyrolysis and a catalytic reforming. The temperature of the catalytic reformer is varied between 500 and 700 °C to achieve an optimum yield quantities and qualities of the products. The hydrogen concentration is maximized at a reforming temperature of 700 °C, and a gas yield up to 52 wt% is achieved. The thermal stable bio-oil produced at 700 °C has the highest calorific value of 36.8 MJ/kg with significantly low oxygen and water content, low viscosity and low TAN (total acid number). Furthermore, the maximum bio-oil and char yields are obtained at the lowest reforming temperature of 500 °C. Overall spent coffee grounds show a great potential as feedstock in the Thermo-Catalytic Reforming for energy and bio-chemicals production.

Palm Waste

Malaysian agro-industrial sector produces considerable quantity of solid palm waste biomass and potential exploitation of this waste residue is necessary for economic and environmental aspects. The Oil Palm Shell (OPS) waste biomass was subjected to multimode microwave pyrolysis at 2.54GHz with coconut activated carbon layers. The microwave power and N2 flow rate were varied to investigate its effects on heating profile, product distribution and bio-oil composition using fixed coconut activated carbon loading. The OPS surface and bed temperature, heating rate, pyrolysis product distribution and bio-oil composition was found dependent on microwave power and N2 flow rate. The highest bio-oil yield of 31 wt% was obtained both at 300W and 600W using 4LPM. The phenol content varied from 34.02-44.42% of GC-MS area with highest value at 300W and 8LPM. Bio-oil from this study also contained 1,1-dimethyl hydrazine of 7.04-13.01 % of GC-MS area.
