Abstract: The present invention proposes a thermochemical battery cycle, termed a Benzene Battery cycle, for efficiently storing electric and/or thermal energy for later and/or distant use. The methods and apparatus herein proposed utilize reversible endothermic fluid and exothermic fluid thermochemical means for efficiently storing H2 in a liquid state at STP. The present invention is generally based on the technology disclosed in U.S. Pat. Nos. 3,225,538, 3,067,594, and 3,871,179, wherein techniques are described for creating a unique thermochemical cycle, termed the Bland/Ewing Cycle (B/E Cycle) after the co-inventors, involving “molecular expansion” and “molecular compression”. The present invention is also based on US Patent Application #18-0954634 which proposes optimizing endothermic and exothermic “segments” for the creation of either Combined Heat and Power (CHP) or Combined Cycle (CC) applications.

Abstract: A system and method for startup of a polyolefin reactor temperature control system having a first reactor temperature control path, a second reactor temperature control path, and a shared temperature control path. In some embodiments, during startup the second reactor temperature control path is configured to allow the temperature of a second reactor to rise due to the heat of the exothermic polymerization reaction occurring within the reactor until reaching a predetermined setpoint temperature. In other embodiments, during startup a first reactor temperature control path is configured to include a heat exchanger used as a cooler, and a second reactor temperature control path is configured to include a heat exchanger used as a heater, to raise the temperature of the second reactor until reaching a predetermined setpoint temperature.
