Membrane reactors including reactive membranes are also discussed in brief. Attention concerning membrane reactors has been shifted from improving equilibrium reactions towards selectivity increase and dosing reactants via the membrane along a reaction zone. Attempts to improve permselectivity of membranes have led to remarkable progress.

Membrane Reactor - an overview | ScienceDirect Topics

Membrane reactors represent a promising alternative for biodiesel production in an intensified process. Currently, the size and number of equipment, as well as the noncontinuous process, are major concerns in biodiesel production. In the membrane reactor process, both catalytic reaction and separation are combined into a single operation unit.

The cuticle is sub-divided into two main layers, exocuticle (with A- and B- layers) and endocuticle, and has an outermost membrane called epicuticle. Beneath the epicuticle, there is a layer of flat, scale like cells which overlap like shingles on a roof. Fig. 1 - 6 shows the longitudinal section of a wool follicle [36].
