A process for the production of synthesis gas from coke is described herein. The process comprises the steps of: (a) subjecting hard coal to dry pyrolysis, resulting in the production of a gas mixture containing hydrogen, methane, nitrogen and carbon monoxide as major constituents and carbon sulphides as minor constituents; (b) subjecting the gas mixture to hydrogenation at a temperature in the range of 200 to 280&#xb0; C. over a sulphidic cobalt molybdenum catalyst provided on an aluminium oxide carrier material; and (c) separating the hydrogen sulphide obtained from hydrogenation from the gas mixture.

Process for the production of synthesis gas from hard coal

The goal of the invention consists in making available a method for supplying fuel to a pressurized gasification system, which ensures, in economically efficient manner, that the emission of pollutants from the coal transfer and the transport is minimized or completely avoided. This is achieved in that a gas that contains at least 10 ppm vol. CO is used for transfer and/or conveying, whereby a gas that contains oxygen is mixed into this gas, and that this gas mixture is heated to a temperature that oxidizes at least 10% of the pollutants contained in the gas.

Method for supplying an entrained-flow gasification reactor with fuel from a storage container

With a method and a system for treatment of a hot crude gas generated by an entrained flow gasification system, removal of the compounds that contain sulfur and carbon is supposed to be undertaken in such a manner that hot gas is made available for further use. This is achieved in that a desulfurization () follows the gasifier (), in series, in the flow path of the hot gas, followed by a solid separation (), whereby behind the solid separation (), a partial stream () of the gas is provided downstream by way of a water quench (), a Venturi scrubber (), a crude gas cooler (), as well as an HO separation () and a compressor (), the flow path () of which is passed back, cooled, into the circuit, behind the gasification () and ahead of the desulfurization system.
