Abstract
Trickle bed reactors are prone to channelling, flooding, and similar flow problems. It has been found that these problems can be avoided by the use of a microporous membrane to separate a reactant fluid phase from a catalysis fluid phase surrounding a catalyst bed. An advantage of such a reactor is that the fluid flows can be separately controlled. An apparatus useful as a trickle bed reactor can include a plurality of microporous hollow fibers arranged in a shell-and-tube configuration within a housing. Such an apparatus is operated with a reactant fluid phase flowing through the fibers and with a catalyst bed on the shell-side of the arrangement.
