Basically, acid hydrolysis of hexoses, pentoses and lignin is called chemical conversion processes. Various studies are carried out on the transformation of biomass with chemical processes. Hydrolysis reactions of biomass with enzymes are rather slow compared to hydrolysis reactions with acids. Acids used in hydrolysis process are examined in two parts. The first is hydrolysis in dilute acid medium, and the second is hydrolysis using sulfuric acid [69]. In Table 1.3, the yield of biofuels obtained under different chemicals and different biomass are indicated.
