Experimental investigation of the pyrolysis of biomass to produce green fuels

This work aims to utilise the experimental approach to perform the analysis of three-biomass feed stocks – bamboo, mustard and camellia and to provide insight into the operation and design of pyrolysis processes. Experiments on biomass fast pyrolysis were performed in a fixed bed (tubular) reactor at a temperature of 500°C and a residence time of 2?min under the constant flow of nitrogen. The analysis of pyrolysis gases and bio oil produced by pyrolysis was done using GC-MS and GC-TCD. Hydrous pyrolysis of biomasses was performed in a high-pressure autoclave for the temperature range 250–400°C and at a pressure of 20?bar with 30?min of residence time. Experiments were conducted both with and without the use of a catalyst. The pyrolysis vapour is made to pass through the catalyst bed of ZSM-5 (Si/Al?=?35). The results for all the biomass samples are then compared.
