摘要： Gasoline product yield is enhanced in a fixed bed methanol-to-gasoline process by splitting the conversion reactor into a series of smaller conversion reactors such that the total amount of catalyst normally present in the single conversion reactor is present in equal quantities in the smaller conversion reactors. The smaller conversion reactors operate sequentially with the next conversion reactor beginning operation only when the preceeding conversion reactor is catalytically exhausted. The by-passing of one or more of the catalyst beds prevents premature deactivation of the catalyst beds downstream of the point at which the reaction products are removed.

摘要： A methanol-to-gasoline conversion process in which the conversion is conducted in a number of reactors which are fed directly by the charge, preferably in equal proportions. A diluent gas, preferably recycled light hydrocarbons separated from the product, is passed in sequence through each of the beds to carry away the heat of reaction. In this way, a high effective recycle ratio is maintained in each bed although the actual recycle ratio for the entire system is low.
