The two-stage conversion of a subbituminous coal has been investigated using an autoclave reactor system. The overall performance of the reaction is found to be determined by the effectiveness of the first-stage operation and by the method of sequencing of the stages. The initial thermal products ca

A simulation of the product distribution obtained from catalytic hydrogenation of a brown coal from the GDR is attempted on the basis of a reaction kinetic model. The main emphasis of the modelling was on the inclusion of a non-isothermal reaction range between an initial temperature of 250°C and th
