ABSTRACT:
The present invention discloses a process for the preparation of syngas from two sources with different hydrogen: carbon ratios, the first source having a low hydrogen:carbon ratio including any one or a combination of coal, brown coal, peat, bitumen and tar sands, and the second source having a high hydrogen:carbon ratio including any one or a combination of natural gas, associated gas and coal bed methane. The sources are converted to syngas and then combined to provide syngas with an optimum hydrogen:carbon monoxide ratio for use in a Fischer-Tropsch process.
