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.

Process for preparing methanol from carbon dioxide and hydrogen with quantitative carbon dioxide utilization

The present invention relates to a process for the calcination of a zeolitic material, wherein said process comprises the steps of

Process for the flash calcination of a zeolitic material

A process for preparing methanol from a carbon-containing feedstock by producing synthesis gas therefrom in a synthesis gas production unit, converting the synthesis gas to methanol in a methanol synthesis unit and working up the reaction mixture obtained stepwise to isolate the methanol, wherein the carbon monoxide, carbon dioxide, dimethyl ether and methane components of value from the streams separated off in the isolation of the methanol 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 synthesis gas production unit and/or to the methanol synthesis unit.

Method for producing methanol from synthesis gas without the emission of carbon dioxide

A process for the calcination of a zeolitic material, wherein the process contains the steps of (i) providing a zeolitic material containing YOand optionally further containing XOin its framework structure in the form of a powder and/or of a suspension of the zeolitic material in a liquid, wherein Y stands for a tetravalent element and X stands for a trivalent element; (ii) atomization of the powder and/or of the suspension of the zeolitic material provided in (i) in a gas stream for obtaining an aerosol; and (iii) calcination of the aerosol obtained in (ii) for obtaining a calcined powder, a zeolitic material obtained by the above process, and its use as a molecular sieve, as an adsorbent, for ion-exchange, as a catalyst, and/or as a catalyst support.

The invention relates to a process for producing a catalyst for the oxidation of ethylene to ethylene oxide, which comprises a) providing a support which comprises alumina and has been impregnated with silver or with a silver-comprising compound and has a temperature T; and b) heating the impregnated support from the temperature Tto a temperature Tat a heating rate of at least 30 K/min, and also the catalyst itself which can be obtained by this process.
