Abstract

Biomass is a promising renewable energy resource for the production of biofuels and value-added chemicals due to the wide range of conversions associated with lignocellulosic biomass. Hydrothermal liquefaction (HTL) is an attractive technology gaining recent interests for the conversion of wet biowastes to biofuels. HTL is a medium-temperature, high-pressure thermochemical process, which produces a liquid Biofuel called biocrude oil. The aim of this study is to investigate the yield of products (biocrude oil, char and aqueous co-product) produced by hydrothermal liquefaction of wet lignocellulosic wastes under catalysts addition. The process condition maintained was at 275ÂșC, 40 min reaction time and 25% solids loading. The biocrude oil yield was optimized with respect to four different alkali catalysts and biomass materials. Sugarcane bagasse showed the highest biocrude yield (25.7%) among the wet biomass samples selected and maximum conversion was achieved by using K2CO3 catalyst. The FTIR analysis of biocrude showed the major presence of aromatic alcohols, aliphatic and aromatic hydrocarbons.
