| 简介 |
A process for regenerating coked particles, which process comprises contacting a hydrocarbon feedstock with solid particles in a reaction zone to produce coked particles, which coked particles are transferred to a regeneration zone in which they are contacted with steam to produce hydrogen and at least one or more oxides of carbon, wherein the solid particles comprise one or more of the following components : (i) an aluminosilicate zeolite comprising one or more of Mn, Ti and Zn; (ii) a Ce-containing aluminosilicate zeolite with a Ce loading of at least 0.05 wt % and/or a molar ratio of total other rare earth elements : Ce in the range of from 0 : 1 to 5 : 1; (iii) a magnesium and aluminium-containing anionic clay; (iv) a material with the Perovskite structure. |
