Реферат: The invention relates to a method for gasifying liquid to pasty organic substances and substance mixtures. According to the invention, the organic substances are converted to a substantially volatile phase in a pyrolysis reactor by contacting them with a hot heat transfer medium. Once a reactant such as water vapor is optionally added, the volatile phase is heated up in a second reaction zone, configured as a moving bed reactor, to such an extent that a product gas with a high calorific value is obtained. The heated up and partially reacted gas mixture is fed to a third reaction zone in which it finally reacts with a catalytically active material, heated up to reaction temperature and different from the heat transfer material, to give the product gas. A flow of hot residual gases of the furnace is used to heat up the heat transfer medium while being cooled.
Catalyst for the fluid bed gasification of biomass contains a dispersed active metal phase containing nickel on a support of magnesium, iron, silicon oxide compound
