It is found that magmatism not only alters the chemical compositions of coal seams, but also brings new minerals to natural coke. Although some studies have related magmatic water to secondary minerals in the natural coke, the mineral formation展开更多

The first stage consists of the catalytic dehydroaromatization of methane characterized by producing hydrogen and aromatics: benzene, naphtalene, toluene, etc. The non-reacted methane plus hydrogen and aromatics produced in the first stage are directed to the second stage to react with the petroleum coke. Basic engineering analysis of proposed two-stage process suggests light petroleum production of 160,000 bbl/day from 20,000 ton/day of petroleum coke actually by-produced from Venezuelan Orinoco’s heavy oil belt. Residual coke should be volatiles free therefore useful as a calcined coke.展开更多
