Instead of producing a large variety of synthetic hydrocarbons like other processes do, my process delivers only synthetic gasolines following 5 CH4+2 CO=C7H16+2 H2O or only synthetic diesels following 11 CH4+5 CO=C16H34+5 H2O thanks to the addition of salt to an iron catalyst or to any other catalyst.

  • Patent number: 6900151
    Abstract: An in situ process for conducting regeneration of spent hydrocarbon synthesis catalyst. Regenerated, but not yet re-activated, catalyst (15) may be introduced into an operating HCS reactor (1) that has catalyst rejuvenation means (14). Any combination of a fresh, activated catalyst, a fresh, passivated catalyst or short-term or long-term deactivated catalysts may already be present in the HCS reactor (1). The regenerated, but not yet re-activated catalyst is activated in the HCS reactor (1) with rejuvenation means (14) at normal process conditions. The HCS reactor (1) receives syngas through the inlet line (3) and releases liquid hydrocarbons through outlet line (4) and gaseous hydrocarbon and unreacted syngas through the offgas line (2). Catalyst is removed from the HCS reactor (1) through the slipstream line (5) and into a filtration unit (6) which is fed with a stripping fluid (7). The filtered catalyst proceeds to the regeneration unit (9) which is fed a regenerative fluid (10).

    Abstract: Promoted skeletal iron catalysts are provided which contain 70-90 wt % iron together with promoters 0-5.0 wt. % copper, 0.1-10.0 wt. % manganese, and 0.1-3.0 wt. % potassium, with the balance being aluminum. The catalysts are prepared by mixing the metal chips or powders uniformly together, then melting and rapidly quenching the molten metals to form a solid metal alloy precursor including the promotor metals except potassium, removing most of the aluminum by caustic extraction/leaching to provide a base skeletal iron form, then loading the potassium promoter from a suitable potassium alcohol solution promoter. After evaporation of the solvent, the promoted skeletal iron catalyst is activated by contact with hydrogen. The promoted skeletal iron catalysts are utilized for F-T synthesis processes at 10-30 wt % catalyst concentration, 200-350° C. temperature, 1.0-3.0 Mpa pressure and gas hourly space velocity of 0.5-5.0 L/gcat-h to produce desired hydrocarbon liquid products.
