Coking and cracking reactions of oil vapor over hot oxidized oil shale
The investigation of cracking and coking reactions of shale oil vapor in the presence of hot oxidized oil shale is conducted both for its intrinsic importance and in support of the modeling effort on the oil shale process. The model includes mass transfer of vapor through the gas film surrounding the shale particles with countercurrent flow of cracked low-molecular weight products, diffusion through the pore system, adsorption onto the internal surfaces, chemical reaction of the adsorbate, and desorption of oil and light gas. Results from two experimental configurations are related to the model calculations, and the application of coking and cracking in the retort process to upgrade oil product are discussed.
