Title: Catalytically controlled reversible dissociation of sulphuryl chloride - enables storage and/or conveyance or heat, obtd. from any source, e.g. solar energy
Inventor: ECKERLIN PETER DIPL CHEM DR
IPC: C09K5/16
Filed: 1979-11-07
Abstract: A device for storing and/or conveying heat by the catalytically controlled and reversible dissociation of sulphuryl chloride to SO2 and Cl2 conveys the SO2Cl2 via a valved conduit to a dissociation vessel with associated heat transfer surfaces and catalyst, and then transfers the mixed gases to store through a compressor and condenser. A synthesis vessel, also with heat transfer surfaces and associated catalyst, is connected via an evaporator to a mixt. store and also to an SO2Cl2 store. Heat from any source, e.g. solar, industrial effluents, power stations or off-peak electrical heat can be used. There are no side reactions producing interfering substances, so the cycle can be repeated indefinitely. The temp. of the recovered heat is independent of the stored heat temp., but is controlled between 50 and 120 deg.C by the reaction pressure. Energy storage is greater than in mechanical or hot water systems or lead accumulators. The evaporators for the compound or the mixed gases can also be used for cold prodn.

Title: Coke oven door - with hollow stopper as gas collecting space for improved gas and coke quality
Inventor: BREIDENBACH DIETER DR
IPC: C10B25/06
Filed: 1980-01-04
Abstract: Door for a coke oven of the horizontal chamber type is fitted with a box-shaped stopper which enters the chamber and keeps the coal charge at a distance from the door to act as a heat protection. The hollow stopper also serves as a gas collecting space because it has no end plates at the bottom or the top. The stopper is made of several rectangular boxy sections with expansion gaps between the sections which are overlapped at the sides facing the coal charge by welded angle iron strips. This improves the gas extraction and the life of the coke oven doors. The coke cake becomes more homogeneous and overheating of the top parts of chamber and door is prevented.
