Hydrogenation Of Coal Process

Coal Hydrogenation - an overview | ScienceDirect Topics

Hydrogenation of bituminous and sub-bituminous coal under mild conditions in absence of solvent, using an impregnated molybdenum – catalyst, show that the low rank coal was are more easily converted to liquids with a high oil to asphaltene ratio. Iron catalysts, in the form of ore and compounds like ferric-oxide, aerosols, ferric-hydroxide precipitated from iron-sulfate solution, has been successfully used in direct hydrogenation reactions. Hydro-liquefaction of coal …

Hydrogenation Process - an overview | ScienceDirect Topics

(m) Hy-Gas process. This is a hydrogenation process in which coal is first pretreated to destroy its agglomertion tendency by mild surface oxidation. Non-agglomerating coals such as lignite and sub-bituminous coals are processed directly without pre-treatment. The coal is then slurried with a light oil (a by-product of the process itself), pumped to the required hydrogasifier pressure level of 1100

US3607158A - Process for the hydrogenation of coal ...

A process for the hydrogenation of coal to produce a methanecontaining gas is described. Powdered raw coal is introduced into a recycling fluidized bed of noncaking material. The coal is rapidly heated and at least partly hydrogenated, and converted into a noncaking powdered char. The process is generally operated at temperatures of 600* to 1,000* C. and pressures of 10 to 200 atmospheres.

The invention relates to a process for the production of liquid hydrocarbons from coal by hydrogenation in the bottom phase with CO / H2 mixtures or hydrogen. The aim of the invention is to increase the effectiveness of the hydrogenation process for a given hydrogenation gas consumption. The invention has for its object to provide a method which allows for increased hydrogenation of an ...

Coal is mixed with emulsifier oil to form a slurry. The coal slurry is pumped to reaction pressure, heated and subjected to catalytically accelerated hydrogenation in the presence of hydrogen. At least a portion of hot gases produced during hydrogenation is drawn off from the reactor and is mixed with the coal slurry which has been pumped to the reaction pressure.

Coal or other solid carbonaceous material is fed under a hydrogenation pressure of about 1,000 to 5,000 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 ...

Bergius process - Wikipedia

The Bergius process is a method of production of liquid hydrocarbons for use as synthetic fuel by hydrogenation of high-volatile bituminous coal at high temperature and pressure. It was first developed by Friedrich Bergius in 1913. In 1931 Bergius was awarded the Nobel Prize in Chemistry for his development of high pressure chemistry.
