✦ Synopsis

The problems associated with assessing the catalytic effects of inherent mineral matter in coal during hydrogenation are discussed in detail. Preliminary results obtained from various relative density fractions of a South African high-mineral-matter coal are reported. Inert matter has been added in an attempt to minimize the complicating effects of agglomeration of the coal particles in order to gain a greater understanding of the relative importance of maceral versus mineral content of the coal during hydrogenation. It is difficult to determine any 'catalytic effect' of mineral matter in coal during hydrogenation since the mineral matter appears to be acting in a physical capacity as an internal diluent, reducing agglomeration of the coal particles. This decrease in agglomeration allows more effective diffusion of hydrogen to the sites of bond rupture and products away from the coal particles as well as maintaining a higher overall surface area for reaction.

Coal is an organic sedimentary rock composed of organic macerals and mineral matter. As it is demonstrated in this paper the discrete mineralogical nature of coal largely influences the wetting of the coal surface by water. Both advancing and receding contact angles were measured using the captive-b

Hydrogenation experiments with batch autoclaves were performed on an Australian Permian bituminous coal (Liddell) using excess of tetralin (3 tetralin: 1 coal by weight) as vehicle. They show that the nickel-molybdenum catalyst, Cyanamid Aero HDS3A, has only a mild effect on the conversion of Liddel
