    摘要: The invention pertains to a multi-stage process for the production of hydrocarbons from syngas comprising hydrogen and carbon monoxide, which comprises the steps of: a) providing a fresh syngas feed to a first stage Fischer-Tropsch reactor and allowing CO and hydrogen to convert into hydrocarbon products at a temperature in the range from 125 to 400° C. and a pressure in the range from 5 to 150 bar absolute, and a gaseous hourly space velocity in the range from 500 to 10000 Nl/l/h; b) feeding the effluent from the first stage reactor to a separation unit; c) removing a gasous effluent stream comprising hydrogen and CO from the separation unit; d) removing one or more other streams comprising hydrocarbon and/or water from the separation unit; e) conveying a first portion of the gaseous effluent stream to a second stage Fischer-Tropsch reactor and allowing CO and hydrogen to convert into hydrocarbon products in the second stage Fischer-Tropsch reactor at a temperature in the range from 125 to 400° C. and a pressure in the range from 5 to 150 bar absolute, and a gaseous hourly space velocity in the range from 500 to 10000 Nl/l/h, whereby the first stage Fischer-Tropsch reactor and the second stage Fischer-Tropsch reactor are separate reactors; f) feeding the effluent from the second stage Fischer-Tropsch reactor to the separation unit; g) removing a second portion of the gaseous effluent stream as off-gas.

    摘要: Method to start a steady state process for producing normally gaseous, normally liquid and optionally normally solid hydrocarbons from synthesis gas, which process comprises the steps of: (i) providing the synthesis gas; and (ii) catalytically converting the synthesis gas at an elevated temperature and a steady state total reactor pressure to obtain the normally gaseous, normally liquid and optionally normally solid hydrocarbons; the method comprising admixing the synthesis gas of step (i) with one or more inert gases to form an admixture stream prior to catalytically converting the synthesis gas in step (ii) at the steady state total reactor pressure and wherein as the activity of the catalyst converting the synthesis gas proceeds towards a steady state, the amount of inert gas(es) in the admixture stream is reduced.

    摘要: The invention pertains to a reactor tube comprising a fixed bed of Fischer-Tropsch catalyst particles, wherein the catalyst particles in 5%-40% of the fixed bed volume at the upstream end have an average outer surface to volume ratio (S/V) of between 3.0 to 4.5 mm-1, and the remaining catalyst particles have an average S/V of between 4.5 to 8.0 mm-1, and wherein the difference between the average S/V of the particles at the upstream end and the remaining fixed bed volume is at least 0.5 mm-1. Additionally the fixed bed volume at the upstream end shows a full-bed apparent catalytic activity per volume unit lower than the full-bed apparent catalytic activity per volume unit in the remaining fixed bed volume and/or the weight of catalytically active metal per weight unit at the upstream end is more than 70% lower than in the remaining fixed bed volume.

    摘要: A process for the preparation of a packed bed comprising an iron enriched cobalt catalyst for use in a Fischer-Tropsch reaction, the process comprising the steps of: (a) providing a packed bed with one or more catalyst particles comprising metallic cobalt; (b) contacting a part of the catalyst particle(s) in the packed bed with an iron containing compound. The process is preferably conducted in situ which conveniently results in an iron containing cobalt catalyst with a higher C5+ selectivity. In certain preferred embodiments the concentration of iron increases towards the surface of the resulting catalyst particles whereas the cobalt concentration is constant which further increases the selectivity of the catalyst to producing C5+ hydrocarbons.
