A HYDROCARBON SYNTHESIS PROCESS USING A COBALT-BASED CATALYST SUPPORTED ON A SILICON CARBIDE COMPRISING SUPPORT

摘要

The present invention relates to a process for producing hydrocarbons, and more particularly to such a process which includes the use of a cobalt-based silicon carbide supported catalyst. According to the invention, there is provided a process for producing hydrocarbons and, optionally, oxygenates of hydrocarbons, the process including: contacting syngas, which includes a mixture of hydrogen and carbon monoxide, with a cobalt-based supported catalyst in a slurry bed of a slurry bed reactor at a temperature above 180°C in the slurry bed, a pressure of at least 10 bar(a) (1000 kPa(a)) in the slurry bed and a water partial pressure (PH2o) reaching at least 5 bar(a) (500 kPa(a)) in the slurry bed; wherein: the cobalt-based supported catalyst has been prepared by (i) introducing a cobalt compound onto and/or into a particulate silicon carbide catalyst support to provide a cobalt loaded silicon carbide catalyst support; (ii) calcining the cobalt loaded silicon carbide catalyst support under non-reducing conditions at a temperature above 400°C to provide a catalyst precursor; and (iii) reducing the catalyst precursor to activate the catalyst precursor and thus providing a cobalt-based supported catalyst.
