A typical renewable energy source, biomass has been studied to produce various goods and energy sources via thermochemical and biochemical routes. The addition of catalytic processes, however, presents a chance to get a wide range of value-added products and gasoline additives. The impact of using catalytic processes to transform the constituents and derivatives of biomass into chemicals of interest via the biorefinery concept. To compare and clarify how catalytic processes affect economic metrics, two biorefineries with and without heterogeneous catalysis were simulated. It was discovered that it is economically possible to include heterogeneous catalysis. The quantity of useful products that may be produced from lignocellulosic biomass is increased by incorporating catalysis into biorefineries.
