Two bituminous coals, a high volatile Eastern Canadian and a medium volatile Western Canadian, were used to investigate the effect of oxidation on yieldsand chemical composition of gases, liquids and chars produced during coal pyrolysis. Pyrolysis experiments were performed at 500Β°C using the Fische
Fixed-bed hydropyrolysis tests have been conducted on a UK bituminous coal (Gedling), the Wyodak Argonne Premium coal sample and the high-sulfur Mequinenza lignite at a pressure of 15 MPa with heating rates of 5 and 300 K min-' . The tar yields and overall conversions increased markedly by -5-20 wt%
Hydropyrolysis (HyPy) of a high-sulphur (4.3 wt% mf) and high-calcite (7.3 wt% mf) subbituminous coal (Sulcis coal) has been studied in a semi-batch fixed-bed reactor under a pressure of 1 or 3 MPa from 580 to 850Β°C. The maximum temperature attained is not necessarily the temperature that the reacto
