A Brief Review of the Thermochemical Platform as a Promising Way to Produce Sustainable Liquid Biofuels in Biorefinery Concept

Energy need of the world is rapidly increasing due to the developing technology, industrialization, and population growth. Nowadays, the alternative resources have been very imported for chemical, fuel and energy production due to decrease in fossil fuel reserves and increase in prices of traditional fuels that supply a significant amount of world's primary energy demand. Biomass-based sources are the most attractive feedstock among these alternative resources and have a high potential to produce power, valuable chemicals, biofuels, and biopolymers. Biomass can be converted into these products by thermochemical, biological or catalytic routes. Thermochemical processes arevery useful and promising way to obtain a wide range of value-added fine chemicals and biofuels from biomass. This review discusses key points of the thermochemical conversion methods and the biofuels obtained as a part of the biorefinery.
