Abstract: A catalyst-containing ceramic dust filter for off-gas or exhaust gas cleaning is prepared by a method comprising the steps of making a water-based impregnation slurry, which comprises a catalytically effective amount of at least one catalytically active metal and an oxide support, to form a catalytically active metal oxide support, impregnating the filter substrate with the impregnation slurry, spraying from the inside to control the amount of liquor while leaving the outer few millimeters of the filter wall dry, and drying the impregnated filter. The impregnated filter is preferably dried by using microwave energy.

Abstract: A reactor system for carrying out an endothermic catalytic chemical reaction in a given temperature range upon bringing a reactant into contact with a catalyst material. The reactor system includes a reactor unit arranged to accommodate catalyst material including one or more ferromagnetic macroscopic supports susceptible for induction heating where the one or more ferromagnetic macroscopic supports are ferromagnetic at temperatures up to an upper limit of the given temperature range. The one or more ferromagnetic macroscopic supports are coated with an oxide, and the oxide is impregnated with catalytically active particles. The reactor system moreover includes an induction coil arranged to be powered by a power source supplying alternating current and being positioned so as to generate an alternating magnetic field within the reactor unit upon energization by the power source, whereby the catalyst material is heated to a temperature within the temperature range by the alternating magnetic field.

Abstract: In a novel process for methanol production from low quality synthesis gas, in which relatively smaller adiabatic reactors can be operated more efficiently, some of the inherent disadvantages of adiabatic reactors for methanol production are avoided. This is done by controlling the outlet temperature in the pre-converter by rapid adjustment of the recycle gas, i.e. by manipulating the gas hourly space velocity in the pre-converter.

Abstract: A float valve for a chemical reactor has a central pipe which glides around a liquid transfer pipe when a liquid level rises and falls, thereby opening for fluid transfer through liquid transfer apertures in the transfer pipe when the liquid level is rising and shutting off for fluid transfer when the float lowers and seals against a sealing ring placed on the transfer pipe below the liquid transfer apertures.

Abstract: The invention relates to a boiling water reactor for an exothermal reaction. The reactor comprises reactant by-pass inserts arranged on top of the upper tube sheet to provide for a catalyst layer on top of the upper tube sheet and also a cooling stream of reactant by-passing the upper layer of catalyst and cooling the upper tube sheet from the temperature rise due to the exothermal reaction taking place in the upper layer of catalyst.
