摘要
It is already known to subject Coal to liquefaction using a slurry of Coal with recycle oil derived from Coal. Such a slurry is generally pumped at a pressure of about 2600 to 3000 psi and is mixed with the Hydrogen, is preheated to around 450° to 500° C. To enhance the reaction of the Hydrogen, the reaction is carried out in the presence of Nickel Molybdenum Catalysts. For increased Yields, the reaction is carried out in an ebullated bed reactor. There is disclosed herein, a method for liquefaction of Coal with Hydrogen, using Hydrogenation Catalyst, comprising the steps of slurrying the Coal in recycle oil, adding Hydrogenation, Catalyst like Nickel Molybdenum under pressure and temperature, characterised in that said Hydrogenation is carried out additionally in the presence of a cracking catalyst, preferably Sodium Carbonate.
