    摘要： A load-following reactor system and associated facilities for improved control of a reactor under varying loads. The load-following reactor may be a tube-cooled reactor for methanol synthesis. A reactant may be controlled by at least one valve element such that a portion of the reactant is fed to the reactor through the reactor tubes, and a portion of the reactant is fed to the reactor after being heated in a heat exchanger. The heated portion of the reactant may be fed to the reactor after the tubes. The valve element may be controlled based on a temperature of the reactor and/or a flowrate of reactant feed to adapt the temperature of the reactor to the changing reactant flowrate.

    摘要： Provided is a method for continuous production of zeolite in which a starting material is continuously supplied to a tubular reactor to produce an aluminophosphate zeolite that contains, in the framework structure, at least aluminum atoms and phosphorus atoms or an aluminosilicate zeolite having 5≦SiO2/Al2O3≦2000. The tubular reactor is heated using a heat medium; a ratio (volume)/(lateral surface area) of the volume (inner capacity) to the lateral surface area of the tubular reactor is 0.75 cm or smaller; and seed crystals are added to the starting material. Through using a small-diameter tubular reactor and heating with a heat medium, it becomes possible to heat sufficiently the entirety of a starting material (zeolite precursor gel) in a short time, and to allow reaction to proceed at a high rate. The occurrence of irregular pressure fluctuations during continuous production of the zeolite can be prevented by adding seed crystals.

    摘要： An apparatus for cracking gases with a supply line (1) for a carbon-containing gas, by means of which the gas is capable of being supplied to a first heat exchanger (5, 9) with a fill of a thermal storage mass, a first combustion chamber (6, 8) which is arranged downstream in the direction of flow of the gas and which, in particular, has a supply device capable of being regulated for another oxygen-containing gas, by means of which a partial oxidation of the carbon-containing gas is carried out by the hypostoichiometric supply of oxygen, and a reactor (7) which is arranged downstream of the first combustion chamber (6, 8) in the direction of flow of the gas which has a fill of a catalytically acting material for the catalytic splitting of impurities of the carbon-containing gas. According to the invention a second combustion chamber (6, 8) with a supply device—in particular capable of being regulated—for an oxygen-containing gas, by means of which a partial oxidation of the catalytically prepared carbon-containing gas is carried out by the hypostoichiometric supply of oxygen, is arranged downstream of the reactor (7) in the direction of flow of the carbon-containing gas, and a second heat exchanger (5, 9) with a fill of a thermal storage mass is arranged downstream of this combustion chamber in the direction of flow of the gas, wherein the direction of flow of the carbon-containing gas is capable of being reversed at least in a region which encloses the first and second heat exchanger (5, 9), the first and second combustion chamber (6, 8) and the reactor (7).
