An adiabatic process is one that occurs without transfer of heat or matter between a thermodynamic system and its surroundings. Chemical reaction engineering deals with determining kinetics, mechanism and rates of the reactions. The reactions are classified as heterogeneous and homogeneous. Heterogeneous reactions are either catalytic or non-catalytic. Catalytic reactions are very important and are mainly used in petroleum and petrochemical industries. Current review summarizes research and studies on non-isothermal processes and reactions.
