  Coal or other solid carbonaceous material is fed under a hydrogenation pressure of about 1, to 5, psi, in the absence of a pasting oil, to a closed, cyclic, high pressure system including a hydrogenation reactor and a reformer, and is contacted, preferably in the presence of a hydrogenation catalyst, with a stream of superheated steam, hydrogen and carbon monoxide-containing gases which. Publisher Summary. This chapter discusses the family of fossil hydrocarbons, particularly petroleum hydrocarbons. The term “petroleum” has come to be progressively expanded to “petroleum hydrocarbons” that include natural products as diverse as natural gas, light crudes, heavy oils, all bituminous substances, and oil-shale kerogens but which, by definition, exclude all types of coal. According to present opinion4'5 hydrogation of coal is a process in which coal free radicals (obtained, for example, by coal thermal treatment) are stabilized by hydrogen. Liquefaction of coal is the partial breakdown of the coal organic matrix via hydrogen transfer, to render the coal soluble in a donor solvent ready for further by: 4.

Bureau of Mines.] -- The Bureau of Mines in cooperation with the El Paso Natural Gas Co. investigated the effect of high temperature and pressure at short residence times on the hydrogenation of a New Mexico coal to. Abstract. A process for converting coals to hydrocarbon values, by intimately contacting coals such as lignite coal with a reagent, e.g., an alkali metal sulfide or polysulfide or an alkali metal hydrosulfide, in the presence of steam, or a combination of steam and hydrogen sulfide, at temperatures between 65 to /sup 0/C; liquid and gaseous hydrocarbons of preselected compositions may be.

CNG may also be mixed with biogas, produced from landfills or wastewater, which doesn't increase the concentration of carbon in the atmosphere. CNG is made by compressing natural gas (which is mainly composed of methane [CH 4]), to less than 1% of the volume it occupies at standard atmospheric pressure. Direct liquefaction of coal is conventionally referred to such a chemically thermal decomposition process in which coal, as raw material, at high temperature, under high hydrogen pressure, and in the presence of catalysts, is finally converted to liquid hydrocarbon mixtures as well as lesser amount of gaseous hydrocarbons meanwhile.
