“…The found the favorable higher lipid content of sorghum improves the economic value of the process. Yuan et al (2019) demonstrate the co-liquefaction of green seaweed (Enteromorpha clathrata) and rice husk (lignocellulosic agricultural waste) to produce bio-oil production of feed stock. Miliotti et al (2019) explored the lignocellulosic ethanol production done at an industrial scale.…”

“…When the feedstock contains significant amounts of moisture, the process of hydrothermal liquefaction (HTL) or solvolysis is preferred for the conversion of biomass to liquid bio‐crude. Solvent liquefaction is another type of liquefaction process that has drawn more attention recently . The reaction of substances with water results in the separation of oil products from the polar byproducts .…”

Lowering greenhouse gas (GHG) emissions: techno‐economic analysis of biomass conversion to biofuels and value‐added chemicals

It is important for researchers to look at alternative fuels to reduce dependence on fossil fuels as a primary source of energy, to protect the environment, and to reduce greenhouse‐gas emissions. An alternative fuel has to be environment friendly and economically viable, both in terms of production and suitability for the modern world. Fuel derived from biomass has long been viewed as a potential replacement. First‐generation biomass‐derived fuels such as bioethanol and biodiesel have already been competing with conventional fuels, assisted by legislation. This review paper assesses the feasibility of adapting and incorporating second‐generation advanced biofuel production technology for the thermochemical conversion of biomass to produce alternative fuels. The conversion technologies considered here are pyrolysis and gasification, and their potential has been examined using techno‐economic assessment (TEA). A brief overview of different business models that can be incorporated during TEA has also been discussed. Techno‐economic assessment data help in determining costs of technologies if they are employed on a commercial scale, especially in terms of per unit cost of product. The review has compiled the technical and economic data available for assessing the types and combination of processes that can assist competitiveness in the existing market. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…Most algae belong to single-celled organisms [5], which means it will be easy to be improved, and can be cultivated by changing the cultivation conditions to produce species more suitable for pyrolysis [6,7]. Compared with the first generation of biofuels [8] (edible biomass, sugar and starch plants) and the second generation of biomass [9] (lignocellulosic biomass), algae has several prominent advantages [10]: (i) high photosynthetic efficiency, which is conducive to alleviate the greenhouse effect problem; (ii) nutrients (N,P) can be extracted from wastewater and returned to the soil by waste product of fertilization; (iii) algae has a short breeding cycle [11], and its process of breeding is easy to realize automation; and (iv) algae does not need to occupy arable lands and is less affected by seasons and regions. According to the analysis composition of algae, algae has high lipid accumulation, which is suitable for the decomposition of bio-oil by heat conversion technology.…”

In order to improve the quality of catalysis products of algae, composite molecular sieve catalyst was prepared by digestion and crystallization of HZSM-5 to reduce the oxygen content of the catalytic products. According to the analysis of the pyrolysis products, the best preparation conditions were chosen of tetra propylammonium hydroxide (TPAOH) solution 2.0 mol l−1, cetyltrimethylammonium bromide (CTAB) solution 10 wt%, crystallization temperature 110°C, digestion–crystallization time: 24–24 h. The results indicate that the main function of catalysts is to promote the conversion of alcohols into hydrocarbons by reducing energy barriers. Catalysed by the composite molecular sieve, the content of alcohols in the pyrolysis products decreased from more than 30% to less than 10%, the content of hydrocarbons increased from 20% to nearly 60%, while all the adverse components remained at a low level, which indicates that the catalytic pyrolysis products are of high quality. The great deoxidation effect of composite molecular sieves is not only due to the expansion of the range of organic matter during re-pyrolysis, but also the increasing of the residence time of pyrolysis products inside the structure for the external mesoporous structure.
