Thermocatalytic pyrolysis of agriculture waste biomass for the production of renewable fuels and chemicals

Abstract

ABSTRACT The present work highlights the thermocatalytic pyrolysis of three different waste biomasses (Groundnut Stalk, Indian Rosewood, and Rice Straw) using meso and microporous catalysts for the effective conversion to fuels and chemicals. Thermocatalytic pyrolysis was found to be highly significant under optimum conditions (Temperature = 500°C, Heating rate = 90°C/min, Biomass particle size = 0.4 mm, and Sweeping gas flow rate = 100 mL/min). All the synthesized catalysts (KIT-6, NbKIT-6, and ZIF-8) were found to be highly efficient, and the maximum liquid yield was observed at 20 wt% of catalyst loading, i.e. 49.35% (KIT-6); 56.57% (NbKIT-6); and 52.74% (ZIF-8), respectively. The results revealed that compared to KIT-6, the maximum liquid yield was observed with NbKIT-6 catalyst i.e. 56.57% (Groundnut Stalk); 58.45% (Indian Rosewood); and 57.57% (Rice Straw), respectively. The proposed strategy will be highly economical and sustainable and the selected biomass could be a promising alternative and renewable energy source.
