PREPARATION METHOD OF CU-ZN BASED CATALYST FOR DIMETHYLETHER SYNTHESIS FOR TRANSPORT FUEL

摘要

PURPOSE: A method for preparing a copper-zinc-based catalyst for synthesizing dimethylether as transporting fuel is provided to improve the performance of a hybrid catalyst for directly synthesizing the dimethylether by increasing the surface area of the catalyst. CONSTITUTION: A cupper precursor and a zinc precursor are mixed. A precipitating agent is added into a precursor mixture. The ph value of the precursor mixture is adjusted. The precursor mixture and the precipitating agent are mixed, and precipitated material is filtered and washed. A drying process is implemented at a temperature between 100 and 120 degrees Celsius for 20 to 30 hours. A plasticizing process is implemented at a temperature between 250 and 350 degrees Celsius for 4 to 8 hours. The precipitating agent is ammonium carbonate or sodium carbonate.
