Patent ID: 8821153

Claim:
A method for the production of a combustible gas from a fuel, comprising, sequentially: (a) converting the fuel, at a temperature that is between 600 and 1000° C. and at a pressure that is lower than 10 bar, into at least a combustible gas that comprises CH 4 , CO, H 2 , CO 2 , H 2 O and higher hydrocarbons, the higher hydrocarbons comprising at least aromatic hydrocarbons, (b) catalytically converting at least part of the higher hydrocarbons, including the aromatic hydrocarbons, at a pressure that is lower than 10 bar, into at least CH 4 , CO, H 2 , CO 2 and H 2 O, (c) removing an amount of H 2 O and an amount of CO 2 from the combustible gas at a pressure that is lower than 10 bar, (d) raising of the pressure of the combustible gas with a compressor, and (e) methanizing the combustible gas of (d) without use of steam.
