Method and apparatus for steam hydro-gasification in a fluidized bed reactor

摘要: A method and apparatus for converting carbonaceous mate rial to a stream of methane and carbon monoxide rich gas by heating the carbonaceous material in a fluidized bed reactor using hydrogen, as fluidizing medium, and using steam, under reducing conditions at a temperature and pressure Suf ficient to generate a stream of methane and carbon monoxide rich gas but at a temperature low enough and/or at a pressure high enough to enable the carbonaceous material to be fluid ized by the hydrogen. In particular embodiments, the carbon aceous material is fed as a slurry feed, along with hydrogen, to a kiln type reactor before being fed to the fluidized bed reactor. Apparatus is provided comprising a kiln type reactor, a slurry pump connected to an input of the kiln type reactor, means for connecting a source of hydrogen to an input of the kiln type reactor; a fluidized bed reactor connected to receive output of the …
