Abstract: The invention relates to a process for the scale-up of a reactor (1) having a supply of a reaction mixture via channels (2) of a burner block (3) to a reaction chamber (4), a high temperature reaction having a short residence time taking place in the reaction chamber (4) and the reaction mixture subsequently being rapidly cooled in a quench area (5). For a throughput enlargement the internal diameter of the reactor (1) is enlarged, the transition of the reaction chamber (4) to the quench area (5) being designed in the form of a gap, which is restricted to a width in the range from 2 to 200 mm.

Abstract: The invention relates to a process for carrying out a high-temperature reaction, in which starting materials are supplied to a reaction chamber (4) through channels (2) of a burner block (3), where in the reaction chamber (4) the high-temperature reaction having a short residence time takes place at a temperature of at least 1500° C. and the reaction mixture is subsequently rapidly cooled in a quench area (5). The cooling takes place first as a direct cooling to a temperature in the range from 650° C. to 1200° C. by supply of an evaporating quench medium and subsequently as an indirect cooling in a heat exchanger.

Abstract: The use of a settling aid in the reactor during acetylene production results in the by-product lime slurry being easier to handle and allows the acetylene producers to use different sources of calcium carbide as well as the calcium carbide manufacturers to use different sources of raw materials to make calcium carbide.

Abstract: Resonant tubes of a pulse combustor are immersed in a bed of solid particles in a reaction zone to provide indirect heat from the pulsating combustion gases to the solid particles of the bed. The bed is maintained in an agitated state by a gas or vapor flowing through the bed. Reactant materials are introduced into the agitated bed and undergo reaction at enhanced rates resulting from heat transfer coefficients at least about twice as high as those of steady flow combustors and an intense acoustic pressure level propagated from the pulsating combustor into the reaction zone. The apparatus is useful, for example, to steam reform heavy hydrocarbons and to gasify carbonaceous material, including biomass and black liquor to produce combustible gas at relatively low temperatures, with steam being utilized as the bed fluidizing medium. Black liquor gasification, utilizing sodium carbonate as bed solids, results in liquor energy and chemical content recovery without smelt production.
