    摘要: Waste water chemical oxygen demand is reduced from a waste water by passing the water in the presence of an oxidizing agent through an adsorbent porous solid substrate, preferably zeolite A, zeolite X, zeolite Y, ZSM-5, erionite, chabasite or activated carbon which has been partially ion exchanged with a water insoluble metal compound, preferably copper (Cu), that facilitates oxidation of the components in the waste water that increase its chemical oxygen demand, such as sulfide, thiosulfate, sulfite, mercaptan, or disulfide. The preferred oxidizing agent is air.

    摘要: A method is provided for high temperature conversion of mercutry-containing hydrocarbon feedstocks to produce a product stream with a negligible mercury level and to protect cryogenic heat exchangers from mercury damage. The feed is treated with adsorbent at high temperatures to remove up to 99% of the mercury. After high temperature conversion, the product stream is treated over a second adsorbent composition to remove any residual mercury and water before the product is cooled and collected.

    摘要: A process and apparatus for fluidized bed combustion using a dense phase combustion zone over a dilute phase combustion zone. When used to regenerate FCC catalyst containing coke with relatively large amounts of NO.sub.x precursors, the catalyst is added to and partially regenerated in the dense phase zone and then falls down into the dilute phase zone. Most of the combustion air is added to the dilute phase and rises into and fluidizes the dense phase zone. NO.sub.x formed in the dilute phase is reduced to N.sub.2 in the dense phase.

    摘要: Emission of noxious nitrogen oxides with the flue gas from the regenerator of a fluid catalytic cracking plant are reduced by incorporating into the circulating inventory of cracking catalyst separate additive particles that contain a copper-loaded zeolite. A particularly effective additive is provided by ion-exchanging ZSM-5 zeolite with cupric ion. With such preferred additive, CO emissions also are reduced, and the recovered gasoline has enhanced octane number.

    摘要: A catalytic cracking process for converting heavy, metals laden feed to lighter products is disclosed. The catalyst regenerator is operated under relatively reducing conditions, to produce a flue gas containing at least 1 mole % carbon monoxide. An additive, preferably alumina, is added to the circulating catalyst inventory to selectively sorb metal contaminants in the feed. The reducing conditions in the catalyst regenerator minimize formation of highly oxidized forms of vanadium, permitting higher vanadium levels to be tolerated on the cracking catalyst. The additive material has a greater affinity for vanadium than the cracking catalyst, and absorbs a disproportionate amount of metals in the feed. Preferably a soft, friable, alumina additive is used which results in the production of alumina fines rich in vanadium, which are discharged from the unit with catalyst fines. The process works especially well in fluidized catalytic cracking processes, with removal of vanadium laden alumina fines from the FCC regenerator with the regenerator flue gas.
