PROCESS FOR PRODUCING CONDENSED-PHASE PRODUCT FROM ONE OR MORE GAS-PHASE REACTANTS.

摘要

A process for producing at least one condensed-phase product from one or more gas- phase reactants in the presence of a solid catalyst having one or more catalyst components, wherein the solid catalyst has two or more regions in which the contact time of the one or more gas-phase reactants with the one or more catalyst components is different.
