Abstract

Graphical abstract: Highlights: Metal oxides are efficient catalysts due to their hydrothermal stability. Promoters can increase catalytic activity and minimizes coking in thermochemical reactions. Alkali-based catalysts increase H2 yield in catalytic gasification. Cobalt catalysts are efficient over iron catalysts in Fischer-Tropsch synthesis. Catalytic liquefaction increases hydrocarbons content and heating value of bio-crude oil. Abstract: The increase in the global population and industrialization has induced an unprecedented increase in biogenic wastes. These biogenic wastes are a potential source of energy and a suitable alternative to energy from non-renewable fossil fuels. Thermochemical technologies are effective ways to transform wastes biomass into biofuels and value-added biochemicals. However, non-catalytic thermochemical conversion technologies are associated with challenges such as low yield, undesirable byproducts and higher levels of heteroatoms affecting the quality of final fuel products. Therefore, there is a need for innovative catalytic approaches to mitigate such challenges. In this review article, various catalyst and their synthesis pathways have been highlighted with specific applications in thermocatalytic conversion technologies. Furthermore, a state-of-the-art review was performed to discuss the impacts of catalysts on the production of biofuels and biochemicals via pyrolysis, gasification, liquefaction, Fischer-Tropsch synthesis and polysaccharides conversion. In addition, an attempt has been made to address the challenges posed by catalysts and their synthesis routes by evaluating the effect of different process parameters.
