Improvement of coal pyrolysis yields by blending coal with lube oil wastes

摘要

The present work studies the copyrolysis of a coal suspended in a lube oil waste. The main objective is to show the technical feasibility of the copyrolysis of coal and waste material slurries, in a fluidized bed and to evaluate the efficiency of the copyrolysis to improve quality and quantity of the products in relation to those obtained from the pyrolysis of coal. Very high yields of C_2-C_4 olephines and BTX were obtained from copyrolysis with the oil waste, so that, quantity and quality of products dramatically increased in reference to coal pyrolysis. Synergic effects on the yields of methane, ethane and ethylene and antisynergic on the yields of C_4-C_6 compounds and BTX were observed.
