Process for producing methanol-to-hydrocarbon-based fuel (MTHF)

The invention relates to a process for producing a methanol-to-hydrocarbon-based fuel (MTHF), and belongs to the technical field of clean energy production processes. The hydrocarbon-based fuel is prepared by etherification and alkylation reaction of methanol, and a closed-path production process of the MTHF is innovatively realized. Compared with the prior art, the hydrocarbon-based fuel production process has the advantages of simplicity in equipment, low economic cost, short flow, safety in operation, environment friendliness, no pollution and high product yield; deep processing treatment such as hydrogenation, isomerization, fractionation and the like is not needed for the obtained product, and the product reaches the discharge standard of G (European) and G (European) IV clean gasoline, so the process belongs to a clean energy production process; and a solution is provided for the great subject of inevitable environmental pollution in chemical production so far, a good path is provided for solving the cu
