Abstract: A shaped catalyst body for heterogeneously catalyzed reactions of organic compounds in the gas-phase in fixed-bed reactors, containing an element from group 3 to 12 of the Periodic Table of the Elements, and having a three-lobed structure with a lateral surface around the lobes, a top cover and a bottom cover, as well as three continuous holes running from one cover side to the other cover side, wherein each hole is assigned to one lobe and wherein the cover sides have outwardly shaped arches, its production and a process for its use in the heterogeneously catalyzed reaction of an organic compound in the gas phase.

Abstract: A process for preparing methanol from carbon dioxide and hydrogen in a methanol synthesis unit and working up the reaction mixture obtained stepwise to isolate the methanol, wherein the carbon dioxide, carbon monoxide, dimethyl ether and methane components of value from the streams separated off in the isolation of the methanol from the methanol reaction stream are combusted with an oxygenous gas, and the carbon dioxide in the resultant flue gas is separated off in a carbon dioxide recovery unit and recycled to the methanol synthesis unit.
