    摘要： A dry, regenerable solid oxide process directed to convert SO.sub.x from the flue gas stream from a power plant, a coal or oil-fired plant or process heat furnace, or an FCC regenerator to elemental sulfur without using a Claus unit, a hydrogen plant, a regeneration gas separation system, or a hydrogenation section. This dry, regenerable solid oxide process is also effective on Claus plant tail-gas. This process uses solid oxides, such as, for example, magnesium aluminates or spinels to remove sulfur oxides from flue gas streams. The solid oxide is then regenerated by a reducing gas to release the sulfur compounds contained on the solid oxide to produce a gas stream comprising hydrogen sulfide, sulfur oxides and elemental sulfur. The elemental sulfur is then condensed and recovered as a product and the resulting gas stream may be recycled to be reprocessed over the solid oxide.

    摘要： The sulfur content of liquid cracking products, especially the cracked gasoline, of a catalytic cracking process is reduced by the use of a catalyst having a product sulfur reduction component containing a metal component in an oxidation state greater than zero, wherein the average oxidation state of the metal component is increased by an oxidation step following conventional catalyst regeneration. The catalyst is normally a molecular sieve such as a zeolite Y, REY, USY, REUSY, Beta or ZSM-5. The metal component is normally a metal of Groups 5, 7, 8, 9, 12 or 13 of the periodic table, preferably vanadium or zinc. The sulfur reduction component may be a separate particle additive or part of an integrated cracking/sulfur reduction catalyst. A system for increasing the oxidation state of the metal component of a Gasoline Sulfur Reduction additive is also provided.

    摘要： A novel oligomerization catalyst and process for upgrading olefins employing new synthetic catalyst of ultra-large pore crystalline material. The new crystalline material exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams at 50 torr and 25.degree. C., a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 Angstrom Units and a hexagonal arrangement of uniformly sized pores with a maximum perpendicular cross section of at least about 13 Angstrom units; and the porous crystalline material is impregnated with at least one oligomerization promoting metal, such as Groups VIIIA metals, preferably nickel.The new process is provided for catalytic oligomerization of olefin feedstock which comprises contacting the feedstock under catalytic conversion conditions with the metal-modified acid metallosilicate solid catalyst having the structure of MCM-41 with hexagonal honeycomb lattice structure consisting essentially of uniform pores in the range of about 20 to 100 Angstroms. The oligomerization reaction is very selective, especially when conducted at temperature of 60.degree. to 120.degree. C. Low severity reaction permits excellent conversion of lower olefins at pressure of about 100-13,000 kPa range and moderate space velocity.
