NOVELTY - The preparation of syngas from hydrocarbonaceous sources with different hydrogen/carbon ratios, comprises converting the source into a syngas stream with hydrogen:carbon monoxide ratio of 0.5:0.8 by partial oxidation with catalytic reforming, and a converting coal bed methane source into syngas stream with hydrogen:carbon monoxide ratio of 5:6 by steam methane reforming. The low ratio source has any one or combination of coal, brown coal, peat, coke, pitch, bitumen and heavy hydrocarbons derived from bitumen.    USE - USE -Used in a Fischer-Tropsch process.    ADVANTAGE - The process ensures to produce very high hydrogen/carbon mono-oxide ratio of syngas.    DETAILED DESCRIPTION - The preparation of syngas from hydrocarbonaceous sources with different hydrogen/carbon ratios, comprises converting the source into a syngas stream with hydrogen:carbon monoxide ratio of 0.5:0.8 by partial oxidation with catalytic reforming, and a converting coal bed methane source into syngas stream with hydrogen:carbon monoxide ratio of 5:6 by steam methane reforming. The low ratio source has any one or combination of coal, brown coal, peat, coke, pitch, bitumen and heavy hydrocarbons derived from bitumen. The low ratio source and a part of coal bed methane source are combined into a combined syngas stream. The H2/CO- ratio of the combined syngas is 1.3:1.7 while using the other part of the coal bed methane stream for hydrogen supply to Fischer-Tropsch process or for upgrading the products of the process and for second stage Fischer-Tropsch reaction, optionally after shifting and/or purification. A portion of the combined stream as a feed is used to Fischer-Tropsch reactor (16). A part of coal bed methane syngas is treated to remove the carbon monoxide and to leave hydrogen, which is used for hydrogenation, hydroisomerisation and/or hydrocracking, catalytic dewaxing, hydrodesulfurisation of condensate, catalyst activation and catalyst regeneration. The Fischer-Tropsch process is carried out by hydrogenation, hydroisomerisation, hydrocracking and catalytic dewaxing, distillation in product streams as naphtha, kerosene, gasoil, waxy raffinate, base oil, wax, solvents, detergent feedstocks, drilling fluids and liquified petroleum gas (LPG).
