THE METHODOLOGY OF CHOOSING THE OPTIMAL SPEED GASEOUS HEAT TRANSFER AGENT IN REACTOR OF SEMICOKING VOLGA OIL SHALE IN FLUIDIZED BED
Justified the choice of calculation methodology for the rate of gaseous coolant required to create a fluidized bed in reactor semicoking of Volga oil shale with considerable polydispersity of the particles of raw materials, as well as changes in temperature and composition of gaseous coolant from the inlet to the outlet of reactor.
Oil shale, semicoking, polydisperse mixture, gaseous heat transfer agent, fluidized bed, porosity, critical speed, required rate of heat transfer agent, methodology of calculation
