Abstract: A process for preparing formaldehyde by gas-phase oxidation of methanol vapor by means of a gas stream comprising molecular oxygen in the presence of a fixed-bed catalyst comprising iron and molybdenum, wherein the process is carried out in a reactor ( 1 ) having heat-exchange plates ( 2 ) which are arranged in the longitudinal direction of the reactor ( 1 ) and have a spacing between them and through which a heat transfer medium flows, inlet and outlet facilities ( 3, 4 ) for the heat transfer medium to the heat-exchange plates ( 2 ) and also gaps ( 5 ) between heat-exchange plates ( 2 ) in which the fixed-bed catalyst is present and into which the methanol vapor and the gas stream comprising molecular oxygen are passed, is described.

Abstract: A method for performing endothermic or exothermic gas-phase reactions on a solid bed of porous catalyst pellets involves supplying or removing the reaction heat by direct heat transfer using a chemically inert ionic liquid medium with a half-life of more than 1 year which is in the liquid state under reaction conditions and is passed through the catalyst bed from top to bottom.

Abstract: Preparation of chlorine involves passing hydrogen chloride and molecular oxygen in a reactor (1) having parallel catalyst tubes (2) charged with fixed-bed catalyst aligned in longitudinal direction of reactor; and alternatively arranged annular and disk-shaped deflection plates (6 and 7) which leave annular passage (9) free. A liquid heat transfer medium circulates between tubes.
