✦ Synopsis
Kinetic studies have been carried out to describe the dependence of the K,CO, catalysed steam and CO, gasification of Westerholt coal char on temperature, pressure and the composition of gasifying agents. By using a low ash char with two different catalyst loadings, it was possible to elucidate the bum-off-effect without taking into consideration the reactions between coal minerals and catalyst.

After a reflection on the gasification-kinetics of alkali-doped coal the catalytic activities of Li, Na, K, Cs were compared. The behaviour of coke doped with alkali carbonate under inert atmosphere was also studied.
Potassium, Na and Ca are excellent catalysts for the gasification of Saran char by steam. Hydrogen inhibits catalysis by K, Na and Ca but promotes catalysis by Fe. The extent of the effect of H,S (or COS) on inhibiting char gasification by steam depends upon whether it is added to wet N, or wet HZ.
Hydrocracking of Athabasca bitumen was studied in a batch reactor at 620-693 K and at an initial hydrogen pressure of 7.2 MPa (at 293 K). The reaction products were separated into coke, asphaltenes, resins, aromatics, saturates and gases. The reaction time versus product yield curves were obtained f
