摘要： Disclosed is a process for removing acid gases from gaseous streams by contacting the stream with an aqueous scrubbing solution containing a heterocyclic nitrogen compound comprised of either a five-- or six--membered ring having a pKa no greater than about 8. Imidazole is a preferred heterocyclic nitrogen compound.

摘要： Hydrogen is produced in a cyclic metals oxidation/carbon reduction process. In particular, elemental iron or cobalt is oxidized in an aqueous solution of an alkali metal hydroxide with the simultaneous generation of hydrogen. The iron or cobalt oxidation products of the reaction are thereafter reduced to elemental iron or cobalt by contact with a carbonaceous reducing agent at elevated temperatures and the reduced material recycled for reoxidation. In an alternate operation, hydrogen is produced in a cyclic electrolytic/carbon reduction process wherein elemental iron or cobalt is electrolytically converted to corresponding oxidation products with the simultaneous generation of hydrogen. The electrolytic cell used in this process comprises a cathode, a magnetic anode that is adapted to attract and retain iron and/or cobalt particles and an aqueous electrolyte. In the electrolytic cell, hydrogen is produced at the cathode and metal particles contained on the magnetic electrode are oxidized to a non-ferromagnetic specie, such as ferrous hydroxide. The non-ferromagnetic species are recovered from the electrolytic cell and thereafter reconverted to particulate elemental iron and/or cobalt by treating the material with a carbonaceous reductant at an elevated temperature.

摘要： Disclosed is a process for selectively removing one or more acid gases from hydrocarbon feed streams containing the same using hydroxyalkyl pyrrolidones as a physical solvent for each of the acid gases or aqueous mixtures containing the physical solvent. The process may be operated using the generalized flow sheet of a typical industrial acid gas treating plant as shown in FIG. 1.

摘要： The instant invention relates to a method of preparing highly dispersed supported Group VIII metal catalysts. The instant invention further relates to the redispersion of sintered or agglomerated supported Group VIII metal catalysts. The process comprises the formation of supported Group VIII metal-phosphorus intermediate compounds followed by the treatment of these supported Group VIII metal-phosphorus compounds in an inert atmosphere at a temperature in the range of about 400.degree. C. to about 750.degree. C., preferably, about 550.degree. C. to about 700.degree. C., most preferably from 630.degree.-700.degree. C. The composition resultant from the dispersion heating step will form the highly dispersed, supported Group VIII metal catalysts by decomposition when reacting with an oxygen containing atmosphere, e.g. air, or reacting with water.
