Retrofit reactor including gas/liquid ejector and monolith catalyst

摘要

This invention relates to apparatus suited for gas-liquid reactions such as those employed in the hydrogenation or oxidation of organic compounds. The apparatus comprises the following: a tank having at least one inlet for introduction of liquid, at least one outlet for removal of liquid, and at least one outlet for removal of gas; a pump having an inlet and an outlet; a liquid motive gas ejector having at least one inlet for receiving liquid, at least one inlet for receiving a reactant gas and, at least one outlet for discharging a resulting mixture of said liquid and said reactant gas to a monolith catalytic reactor. Circulation of liquid is effected from the tank to the ejector, to the monolith catalytic reactor and then back to the tank. Gas is drawn from the tank to the ejector and mixed with the liquid prior to entry to the catalytic reactor.
