| titleOfInvention | Catalyst for converting alcohol ether into high p-xylene content aromatic hydrocarbon, preparation method and reaction process thereof |
| abstract | The invention belongs to the technical field of chemical industry catalysis, and particularly relates to a catalyst for converting an alcohol ether into a high p-xylene content aromatic hydrocarbon, a preparation method and a reaction process thereof. According to the present invention, a molecular sieve loading a metal, phosphorus and rare earth and other reinforcing components are adopted to form high mechanical strength particles, and the surface acid sites are 0.01-1% (molar fraction) of the total acid sites of the catalyst; the preparation method relates to a method for forming composite particles through multiple forming and controlling acid of the surface of the composite particles; and the catalyst can be applicable for fixed beds, moving beds and fluidized beds, and can be provided for converting methanol or dimethyl ether raw materials containing water and a small amount of high carbon alcohol and ester, wherein one-time conversion efficiency of the methanol or the dimethyl ether at a temperature of 450-520 DEG C and a space velocity of 0.2-30 h <-1> is more than 99.9%, the total (carbon-base) yield of the aromatic hydrocarbon is more than 60%, and the mass fraction of the p-xylene in the xylene is more than 90%. |
