Process for the preparation of hydrocarbons, and hydrocarbons so prepared. |
摘要 |
A process for the preparation of an aromatic hydrocarbon mixture, in which a mixture of carbon monoxide and hydrogen with an H2/CO molar ratio between 0.25 and 0.75 is contacted with a mixture of two catalysts of which one (A) is capable of catalysing the conversion of an H2/CO mixture into acyclic oxygen-containing hydrocarbons and the outer (B) is a crystalline silicate, (A) contains zinc and chromium and the composition of B expressed in moles of the oxides, is as follows: y(1.0 +/- 0.3)M2/nO . y(a Fe2O3 . b Al2O3) . SiO2, wherein M = H and alkali metal or alkaline-earth metal; n = the valency of M; O < y </= 0.1; a >/= O; b >/= o, and a + b = 1; An amount of water is added to the H2/CO mixture which - in %mo l based on the H2/CO mixture - is at least 2.5 and at most <MATH> wherein: R = the H2/CO molar ratio of the feed, and V = the consumption ratio of the H2/CO mixture obtained under the conditions at which the above-mentioned process is carried out, but without water addition. The process is carried out at a temperature of 200-500 DEG C, a pressure of 1-150 bar and a space velocity of 50-5000 NI gas/I catalyst/h. |
