The present invention concerns a multifunctional catalyst for the conversion of CO.sub.2 into useful products, such as CO via the reverse water gas shift reaction. The catalyst according to the invention efficiently combined a water sorption functionality with at least one catalytic functionality into a single particle, by having a solid water sorbent impregnated with at least one metal capable of converting CO.sub.2 from a gaseous mixture comprising H.sub.2 and CO.sub.2. The catalyst according to the invention allows for higher selectivity in the conversion of CO.sub.2, at more lenient conditions in terms of temperature and pressure, and improved stability of the catalyst itself. The invention also concerns a process for converting CO.sub.2, utilizing the catalyst and the use of the catalyst in the conversion of CO.sub.2.

A process for the production of alkyl ethers including feeding a hydrocarbon feedstock and a first alcohol feedstock to a fixed bed reactor containing an etherification catalyst. The hydrocarbon feedstock and the first alcohol feedstock are contacted in the first fixed bed reactor to react the isoolefins with the alcohol in the presence of the etherification catalyst to produce a first product stream. The first product stream is fed together with a hydrogen feedstock and a second alcohol feedstock to a catalytic distillation reaction system containing a trifunctional catalyst to concurrently isomerize at least a portion of the alpha-olefins, hydrogenate at least a portion of the diolefins, and etherify at least a portion of the isoolefins and alcohol, producing a bottoms product comprising the one or more ethers and an overhead product comprising n-alkanes, isoalkanes, unreacted alpha-olefins, unreacted internal-olefins, unreacted isoolefins, and unreacted alcohol.

The process and apparatus according to the invention allow the production of chemical compounds without the use of catalysts. For this purpose, the reactants necessary for the desired products are fed to compression reactors. In addition, the reaction conditions are controlled by means of an electronic control device. For this purpose, among other things, the compression reactors are combined with an electric motor, thereby influencing the residence time in the reactors. In addition, it is planned to raise the reactant pressures with the help of a compressor. In addition, the operating conditions are recorded with suitable sensors and/or analysers.
