It has been discovered that via biochemical and thermochemical routes, biomass may be converted into a variety of goods and energy sources. To get a wide range of value-added products and gasoline additives, however, catalytic processes need be included. the impact of using catalytic processes to transform biomass derivatives and its constituent parts into chemicals of interest using the biorefinery concept. To assess and clarify the catalytic processes' influence on economic metrics, two biorefineries were simulated, one with and one without heterogeneous catalysis. It was found that, from an economic standpoint, heterogeneous catalysis might be included. By incorporating catalysis into biorefineries, more value products may be produced from lignocellulosic biomass.
