VERFAHREN ZUR HERSTELLUNG VON IN KONDENSIERTER PHASE VORLIEGENDEM PRODUKT AUS EINEM ODER MEHREREN IN DER GASPHASE VORLIEGENDEN REAKTANTEN

摘要

Process for the production of a condensed-phase product from one or more gas-phase reactants, by feeding one or more reactants into a reactor, in which reactor the one or more reactants react in the gas-phase in the presence of a solid catalyst having one or more catalyst components to produce at least one product which is in a condensed-phase under reaction conditions. The solid catalyst is present as a bed having 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.
