Moving Bed Reactors Chemical EngineeringFluidized bed reactor Wikipedia
Moving bed reactors are catalytic reactors in which the catalyst moves through the reactor along with the reactants They are open systems and operate at steady state They are open systems and operate at A fluidized bed reactor FBR is a type of reactor device that can be used to carry out a variety of multiphase chemical reactions In this type of reactor a fluid gas or liquid is passed through a solid granular material usually a catalyst possibly shaped as tiny spheres at high enough velocities to suspend the solid and cause it to

Trickle Bed Reactors A trickle bed reactor is a fixed bed where liquid flows without filling the spaces between particl Like with the fixed bed reactors the liquid typically flows downward At the same time gas is flowing upward The primary use for trickle bed reactors is hydrodesulfurization This reactor is often utilized in order to handle feeds with extremely high boiling points The reaction took place in fixed bed catalytic reactor The catalyst was a mixture of phosphoric acid on a clay base The reactor produced a mixture of cumene propylene and benzene These materials were separated in two distillation columns the depropaniser and the benzene column There were two tanks that could be used to store cumene before it was sent to Oxidation Oxidation This section
