Abstract: Ammonia and 5 to 40 volume percent hydrogen sulfide containing vapors which arise in the vaporization of process water from hydrogenation or a crude oil fraction or in gas treatment in a coking plant, can be subjected in a cracking catalyst reactor to breakdown of the ammonia to nitrogen and hydrogen. The resulting process gas is cooled to 250.degree. to 350.degree. C. and is fed to a hydrogenation reactor where any sulfur is hydrogenated to the hydrogen sulfide. The process gas can then be subjected to further treatment without the danger of sulfur blockage of the process lines. For example, the hydrogen sulfide can be removed by a selective absorption process.

Abstract: A method of generating electric energy from biological raw materials. A biological raw material is used which is substantially free from sulfur of natural origin. A combustion gas is generated from biological raw materials in an oxidation reactor by partial oxidation. An oxygen/biological raw material proportion of ingredients and a gas phase temperature are maintained which ensure a combustible gas virtually free of nitrogen oxides. After removing suspended matter from the combustible gas in a separator, the combustible gas is converted into electric energy in fuel cells having a porous anode, a porous cathode and a suitable electrolyte.

Abstract: A method for the inactivation of prions, viruses and other infectious agents, which might be present in a biological raw material (e.g. plasma for the preparation of albumin), leaving the desired biological product (e.g. BSA, HSA) intact. To achieve this, the biological raw material is treated with a chaotropic agent, e.g. urea or siodium thiocyanate for approx. 18 hours. Before this, a detergent, e.g. sodium dodecyl sulfate, as well as ethanol or methanol can be added, and the solution can be heated to 70.degree. C. and kept at this temperature for 30 minutes. After cooling and acidification, denatured globulins can be removed. By modifications of this process (e.g. different concentrations, pH-values, temperatures etc.) a wide range of biological products (serum, plasma, proteins, peptides, gangliosides etc.) can be treated and rendered free of viruses, prions and all other infectivity.
