Claim:
1. A reactor system for use with an exothermic reaction comprising the hydrogenation of a fluoro-olefin compound, said system comprising in combination, (a) as a first reactor in the system, a trickle-bed reactor which does not include either a heating or cooling medium, and (b) as a second reactor in the system, a shell-and-tube reactor which comprises a temperature control system selected from the group consisting of a heating medium, a cooling medium, and both a heating and a cooling medium, wherein the reactors are separated by a heat exchanger; wherein the trickle bed reactor comprises a fixed bed of reactor catalyst and two phases in the reactor; wherein the shell-and-tube reactor comprises a multi-stage, multi-tube, shell-and-tube heat exchanger which contains reactor catalyst in all tubes; and wherein the reactor system provides for the removal of heat and provides the ability to control reaction temperature and/or reaction progression.
