Abstract

The present invention is directed to a process for the production of hydrocarbon product from two different hydrocarbonaceous feedstocks comprising the steps of preparing a feed syngas having a hydrogen/carbon monoxide [H2/CO] molar feed ratio suitable for Fischer-Tropsch synthesis, wherein the feed syngas is prepared by combining a first syngas having a H2/CO molar ratio below the molar feed ratio and a second syngas having a H2/CO molar ratio above the molar feed ratio; the first syngas is prepared from a liquid hydrocarbon comprising feedstock as the sole source of carbon in a first syngas manufacturing process comprising a non-catalytic partial oxidation step; the second syngas is prepared from a methane comprising feedstock as the sole source of carbon in a second syngas manufacturing process comprising a heat exchange reforming step and an auto-thermal reforming step; and the first and second syngas manufacturing processes are operated in parallel.

Dependent claims

A process for the production of hydrocarbon product from two different hydrocarbonaceous feedstocks comprising the steps of:

(a) preparing a feed syngas comprising hydrogen and carbon monoxide having a hydrogen/carbon monoxide [H2/CO] molar feed ratio suitable for Fischer-Tropsch synthesis and
(b) using the feed syngas in a Fischer-Tropsch process using one or more syngas conversion reactors thereby obtaining the hydrocarbon product,
wherein
(i) the feed syngas is prepared by combining a first syngas having a H2/CO molar ratio below the molar feed ratio and a second syngas having a H2/CO molar ratio above the molar feed ratio;
(ii) the first syngas is prepared from a liquid hydrocarbon comprising feedstock as the sole source of carbon in a first syngas manufacturing process comprising a non-catalytic partial oxidation step;
(iii) the second syngas is prepared from a methane comprising feedstock as the sole source of carbon in a second syngas manufacturing process comprising a heat exchange reforming step and an auto-thermal reforming step;
and
(iv) the first syngas manufacturing process and the second syngas manufacturing process are operated in parallel.
