Abstract: The inert gas, particularly He, is cooled in a heat exchanger as in DT 1751090. The most efficient type of heat exchanger is a liquid metal bath, particularly liquid Pb. Specifically the gas is circulated from the heat source to the heat exchanger and back to the heat source.

Abstract: Removal of S cpds. from gaseous or liquid hydrocarbons by contact with solid absorbents at 15-100 degrees C, derived from cpds. of formula Me2+6 Me3+2 (OH)16CO3.4H2O, by calcination and subsequent reduction in hydrogen, and in which Me2+ is Fe, Cu, Co or Ni and Me3+ is Al or Cr. Used for treatment of fractions with upper boiling limit up to 250 degrees C, e.g. refinery gases, liquid gases (e.g. propane and butane), petrol fractions and esp. kerosene fractions. The hydrocarbons can be treated in gas or liquid phase at relatively low temps. (below 100 degrees C) and sulphur contents below 1 ppm obtained, as required in jet fuels. The absorbent can be highly loaded with hydrocarbon throughputs of 1-10 kg/l/h. Where the initial S content is low, the metal content in the absorbent can be small e.g. by dispersing on an alumina-silica carrier.
