WebJan 5, 2024 · Nevertheless, powdered Raney catalysts cannot be applied in fix-bed reactors. Currently it is mainly employed in slurry phase reactors for small batch production. In this case, catalytic selectivity is hard to control, and Raney catalysts are demanded to be separated from reaction medium [1]. Web5.5.4 Microwave fluidized bed applicators. Fluidized bed reactors are widely used in material processing industries for processes that require very good heat and mass transfer between particles and a gas. The energy provided to the fluidized bed typically comes from the warm gas that fluidizes the bed as well.
WebFluidized-bed reactors offer a much higher efficiency in heat exchange, compared to fixed beds, and better temperature control, due to the turbulent gas flow and rapid circulation. … WebFluidized-bed reactors are used for the roasting of sulflde ores and regeneration of catalytic cracking catalyst, and fixed-bed reactors are used to remove sulfur compounds from ammonia synthesis feed gas. When regeneration of the solid reactant is desired, two or more reactors operating in parallel are required if continuous, steady-state ...
