Reactors - processdesign

Types of reactors. Heterogenous catalytic reactors are commonly classified by the relative motion of the catalyst particles. Reactors with insignificant motion of catalyst particles Fixed bed reactors. A fixed bed reactor is a cylindrical tube filled with catalyst pellets with reactants flowing through the bed and being converted into products.
