  • Situations where adoption of a multiphase reaction process is unavoidable:

    1. in the case where phase difference occurs among reactants, impurities in feed, heterogeneous catalysts and micro-organisms:

    1. in the case where phase difference occurs amongst products and byproducts

  • a) gas-solid or liquid-solid reactions;

    b) gas-liquid reactions;

    c) reactions between immiscible liquids;

    d) solid-solid reactions;

    e) gas or liquid reactions with immobilized catalysts, immobilized enzymes or micro-organisms.

    Examples of case 1

  • a) Reactions forming gases or solids from liquids;

    b) reactions forming liquids or solids from gases;

    c) reactions forming gases or liquids from solids

    Examples of case 2
