Title: Carbon black from coal by the HYDROCARB process

Abstract

The HYDROCARB process was conceived and developed for the purpose of producing a clean carbon fuel and coproduct gaseous and liquid fuel coproducts from any carbonaceous feedstock and particularly from coal. The process basically consists of two major steps. In the first step, coal is hydrogenated to produce methane. In this step, the carbonaceous raw material is gasified with a recycled hydrogen-rich gas stream to form a light hydrocarbon, methane-rich gas, while the non-volatile ash remains behind. With the optional addition of limestone to the feed material, sulfur in the feedstock is removed as non-volatile calcium sulfide which is later oxidized to calcium sulfate for disposal. The methane-rich gas which also contains carbon monoxide and smaller amounts of water and carbon dioxide is sent to a recuperative condenser. For the production of methanol, the carbon monoxide and hydrogen in the process gas is catalytically combined to produce methanol. The deoxygenated methane-rich gas stream is then sent to a methane decomposer where the methane is cracked to pure particulate carbon and hydrogen gas. The pure carbon is removed as a clan product and most of the hydrogen-rich gas is returned to the coal hydrogenator. The two basic steps are than coalmore » hydrogasification in a hydropyrolysis reactor (HPR) and methane decomposition in a methane pyrolysis reactor (MPR). 6 refs., 3 figs., 2 tabs.« less
