Abstract: A PROCESS FOR RECOVERING BOTH MECHANICAL ENERGY AND THERMAL ENERGY FROM THE EXHAUST GASES OF AN ETHYLENE OXIDE SYNTHESIS REACTOR. THE EXHAUST GASES ARE PASSED IN HEAT EXCHANGE RELATIONSHIP WITH BOILER FLUE GASES WHICH ARE USED TO DRIVE A GAS TURBINE WHICH IS COUPLED TO THE DRIVE SHAFT OF AN AIR COMPRESSOR. THE EXHAUST GASES DISCHARGING FROM THE TURBINE ARE THEN BURNED IN THE STEAM BOILER. STEAM GENERATED IN THE BOILER IS USED TO DRIVE A STREAM TURBINE WHICH IS ALSO COUPLED TO THE DRIVE SHAFT OF THE AIR COMPRESSOR.

Abstract: A method is disclosed for the polymerization of isobutylene and, in particular, the copolymerization of isobutylene and isoprene, by contacting the monomers with a catalyst system constituted by (a) an organoaluminum compound (e.g., Al(C2H5)2Cl) and (b) an oxide or anhydride of an element belonging to Group VI B or VII B of the periodic system (e.g., SO2), in a liquid reaction medium, wherein the molar ratio of compound (b) to compound (a) is less than 1, at a temperature in the range of about -40* to +15*C.
