Utilization of urban and pulping wastes to produce synthetic fuel via pyrolysis

Major byproducts of delignification processes of lignocellulosic biomass include lignin degradation products. Lignin and its degradation products have fuel values. The yields of liquid and gaseous products from the solid waste pyrolysis increase from 23.8 to 49.7% with temperatures increasing from 584 to 683 K. The yields of liquid and gaseous products from the black liquor pyrolysis increase from 7.3 to 55.0% with temperatures increasing from 500 to 800 K. The yields of liquid and gaseous products from pyrolysis of the solid waste and black liquor samples increase with increasing temperature. This increase is very sharp for the yields of liquid products from the solid waste at the same temperature range.
