Abstract: The invention relates to a method for coating internal fittings in a reactor, except for electrically heatable, at least partly open-cell foams, with a catalytically active material or a precursor therefor. According to said method, aerosol containing the catalytically active material or the precursor therefor as a dispersed phase is provided and is directed through the reactor at a speed which is set in such a way that the dispersed phase of the aerosol deposits on the internal fittings of the reactor.

Abstract: A reactor (1) for preparing phosgene by gas-phase reaction of carbon monoxide and chlorine in the presence of a solid catalyst, which reactor has a bundle of parallel catalyst tubes (2) aligned in the longitudinal direction of the reactor whose ends are fixed in tube plates (3) and have a cap (4) at each end of the reactor (1), and has deflection plates (6) which are aligned perpendicular to the longitudinal direction of the reactor in the intermediate space (5) between the catalyst tubes (2) and leave free passages (7) located alternately opposite one another on the interior wall of the reactor, and in which the catalyst tubes (2) are charged with the solid catalyst, the gaseous reaction mixture is passed from one end of the reactor via one cap (4) through the catalyst tubes (2) and is taken off from the opposite end of the reactor (1) via the second cap (4) and a liquid heat transfer medium is passed through the intermediate space (5) around the catalyst tubes (2), where the reactor (1) has no tubes in the region of the passages (7), is proposed.

Abstract: A process for coating internals in a reactor, except for the coating of electrically heatable, at least partly open-cell foams, with a catalytically active material or a precursor thereof, in which an aerosol which contains the catalytically active material or the precursor thereof as a disperse phase is provided and the aerosol is passed through the reactor at a rate in the range from 0.1 to 4 m/s, which is established so that the disperse phase of the aerosol is deposited on the internals in the reactor.

Abstract: Reactor (1) comprises several contact tubes (2) in parallel in the reactor inner chamber and welded to the reactor base. Caps are on both reactor ends to form a cap chamber. A fluid reaction medium is introduced into the tubes via one cap chamber, flows through the contact tubes and flows out through the other cap chamber. The contact tubes are in two or more contact tube regions (7) thermally separated from each other. An Independent claim is also included for a process for testing catalyst systems. Preferred Features: At least one contact tube with a sleeve (9) for receiving a thermocouple and filled with Al2O3 is in one or more contact regions and closed at both ends. A cover is provided for the contact tubes of one or more contact regions.

Abstract: The invention relates to a pump (1) comprising a pump feed tube (13) for transporting a heat exchange medium (6) for a reactor containing a bundle of catalyst tubes (2). The pump (1) has a housing (14) that surrounds the pump feed tube (13) and comprises an opening (15) in the lower part of the housin g (14), which allows the heat exchange medium (6) that is drawn from the lower section of the reactor by the pump (1) to flow into the housing (14). The medium flows upwards in the section lying between the internal wall of the housing (14) and the external wall of the pump feed tube (13), optionally ov er a heat exchanger (18) and into the interior of the pump feed tube (13) via a n opening (16) in the upper section of said pump feed tube (13). The medium th en flows through the pump feed tube from top to bottom, into the reactor via an opening (17) in the lower section of said tube (13) and into the upper secti on of the intermediate chamber between the catalyst tubes (2).
