摘要： A process for adsorbing hydrocarbons from an acid gas stream includes passing the acid gas stream through an adsorbent which selectively removes hydrocarbons, desorbing the hydrocarbons from the adsorbent and contacting the desorbed hydrocarbons with an acid gas removal solution to remove acid gases which have been coadsorbed with the hydrocarbons. The process is particularly useful in removing hydrocarbons from a hydrogen sulfide-containing stream which is being directed to Claus processing for conversion into elemental sulfur. Useful adsorbents include crystalline titanium silicate molecular sieves containing titania octahedral sites such as ETS-10 and similar materials, as well as Y-type zeolites having a silica to alumina mole ratio of less than 15 and a reduced sodium content.

摘要： A zeolite catalyst composition is provided in which a first or upstream zone of the catalyst has a lower metal (e.g., iron or copper) promoter loading than the metal promoter loading of the second or downstream zone of the catalyst. The first zone may contain from none up to about 1 percent by weight of the promoter and the second zone may contain from about 1 to 30 percent by weight promoter. The zeolite may be any suitable zeolite, especially one having a silica-to-alumina ratio of about 10 or more, and a kinetic pore size of about 7 to about 8 Angstroms with such pores being interconnected in all three crystallographic dimensions. The method of the invention provides for passing a gaseous stream containing oxygen, nitrogen oxides and ammonia sequentially through first and second catalysts as described above, the first catalyst favoring reduction of nitrogen oxides and the second catalyst favoring the oxidation or other decomposition of excess ammonia.

摘要： A method comprising passing through a zeolite catalyst, a gaseous stream containing nitrogen oxides, ammonia and oxygen to selectively catalyze the reduction of nitrogen oxides and, if excess or unreacted ammonia is present, to oxidize the excess of unreacted ammonia with oxygen to hydrogen and water. The method includes the use of a zeolite catalyst composition which comprises a metal (e.g., iron or copper) promoted zeolite, the zeolite being characterized by having a silica to alumina ratio of at least about 10 and a pore structure which is interconnected in all three crystallographic dimensions by pores having an average kinetic pore diameter of at least about 7 Angstroms. Promoted zeolites of the above type have demonstrated high tolerance for sulfur poisoning, good activity for the selective catalytic reduction of nitrogen oxides with ammonia, good activity for the oxidation of ammonia with oxygen, and the retention of such good activities even under high temperature operations, e.g., 400 DEG C or higher, and hydrothermal conditions.

摘要： A system is made available, by means of which the sulphur oxide content in emissions, which pass into the atmosphere in the combined waste gases from the selective vaporisation and, in fluid catalytic cracking, of the improved charge material resulting in the selective vaporisation, can be controlled. The invention leads to a reduction in the sulphur oxide content of the waste gases from the FCC regenerator and the burner for the selective vaporisation, and a new controllable variable for a heat-balanced FCC unit is provided. The cracking catalyst used is capable of reversibly reacting with the sulphur oxides in the combined waste gases, in order to recycle the sulphur to the reactor, where it is - at least partially - converted to hydrogen sulphide which is removed from the reaction products in the normal treatment sequence of the cracked products from the reactor. In the system disclosed, the mixture of the waste gases is cooled down and then contacted with the hot regenerated catalyst from the regenerator, in order to induce the sorption of the sulphur oxides by the catalyst and to cool the catalyst down for the purpose of controlling the reaction parameters in the FCC reactor.
