| titleOfInvention | Combination catalyst system and use thereof |
| abstract | The invention relates to a process for converting synthesis gas to produce aromatic hydrocarbons and light hydrocarbons together and the catalyst used. The catalyst system has catalytic activity for syngas conversion and aromatic/light hydrocarbon synthesis. The synthesis gas conversion activity is provided by Cr-containing oxide catalysts, and the aromatic/light hydrocarbon synthesis activity is provided by solid acid catalysts including MFI or MEL structured molecular sieves and modified molecular sieves. Wherein, the silicon-aluminum ratio of the molecular sieve with MFI or MEL structure/modified molecular sieve ranges from 12 to 250. Catalyst forms include composite catalysts or multi-stage catalyst systems. Under the condition that the raw material H 2 /CO molar ratio is 0.25-5.0, and/or the reaction temperature is 300-500°C, and/or the pressure is 0.5-10.0MPa, and/or the volume space velocity is 1000-20000h- 1 , the synthesis gas can be produced in one stage High-efficiency conversion in a multi-stage or multi-stage catalyst system to generate aromatics and light hydrocarbons. The invention provides a non-Fischer-Tropsch route and a new route for realizing direct conversion of synthesis gas to produce aromatics and co-production of light hydrocarbons in one step. |
