Assessment of the tire role in coal-tire hydrocoprocessing

摘要

This paper analyzes the role performed by rubber from tire in coal-tire coprocessing when tire is added to coal hydrogenation. A low-rank coal (SAMCA, Spain) and discarded scrap tires (steel thread and the textile netting were previously removed) were batch processed in tube reactors at various hydrogenating atmospheres (10, 7.5, 5, and 1 Mpa of hydrogen) and in inert atmosphere (1 Mpa of nitrogen) for 30 min at 400 deg.C. two feed mixtures, 80/100 coal/20/100 rubber (4/1 ratio), and 20/100 coal/80/100 rubber (1/4 ratio), and both raw materials were processed separately.
