    摘要: Improved processes are disclosed for increasing gasoline yield from a gas oil at a constant riser top temperature by introducing a quench fluid, such as liquid water, butane, or lighter hydrocarbons or an alcohol or ether into a riser downstream of the site where the gas oil and/or catalyst are injected. In another embodiment of the invention the introduction of quench fluid, acting as a heat sink, can be used to increase octane number while avoiding significant formation of wet gas as is observed when higher octane number is achieved by generally increasing the overall riser temperature. This invention further provides an integrated process wherein the C 4 - product from an FCC riser unit which is limited to a predetermined top temperature maintained by injecting a quench fluid intermediate the inlet and outlet of the FCC riser is combined and contacted with a zeolite catalyst in a turbulent fluid bed under conditions of severity to upgrade the light olefin-containing gas to heavier hydrocarbons, especially gasoline.

    摘要: Process for production of alcohol or ether by hydration of olefinic feedstock containing at least one lower alkene by contacting the olefinic feedstock and water in a hydration zone with porous solid metal oxide acidic olefin hydration catalyst under olefins hydration conditions, characterized by pretreating porous solid catalyst, such as acid zeolite, prior to contacting with the olefinic feedstock with a wetting agent containing at least one polar aliphatic oxygenated hydrocarbon to substantially wet the solid catalyst and sorb the wetting agent into pores of the solid catalyst. After initiating hydration reaction by feeding the olefinic feedstock and water, increased catalytic activity is obtained. The process is particularly useful for making isopropanol and DIPE from propylene and water.

    摘要: In a fluidized combustion process for removing coke from a particulate material, the material is fluidized in a first zone and a second zone and coke on the particulate material is burned in the first zone to produce a combustion gas containing CO, the conditions in the first zone being such that the CO can convert NO x in the combustion gas to nitrogen. The combustion gas is then passed from the first zone to the second zone and a CO combustion promoter is selectively provided in the second zone to convert CO to CO₂.
