Fixed bed vs packed bed reactors
WebTrickle-bed reactor. A trickle-bed reactor ( TBR) is a chemical reactor that uses the downward movement of a liquid and the downward (co-current) or upward (counter-current) movement of gas over a packed bed of ( catalyst) particles. It is considered to be the simplest reactor type for performing catalytic reactions where a gas and liquid ...
