Abstract

The mineral reactions of Israeli oil shale fed to the GENESIS (Generation of Energy from Shale of Israel) split-stage fluidized-bed reactor have been studied by infrared. X-ray and chemical means. Organically bonded sulphur released during pyrolysis reacts with oxygen from the fluidizing air and with CaO resulting from decomposition of calcite to form CaSO₄, mostly in a surface layer. At pyrolysis and coke-oxidation temperatures near 600°C, kaolinite reacts with calcite to form amorphous modified metakaolinite. At organic gas combustion temperatures near 1000°C, the amorphous phase in overhead fines reacts with additional calcite and quartz to yield gehlenite and larnite.
