    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: An improved process and apparatus are disclosed for fluidized bed catalyst regeneration in a cross-flow type regenerator. A baffled coked catalyst inlet located within the dense bed of catalyst disperses and distributes coked catalyst flow in a direction generally normal to the direction of flow in the catalyst inlet. The baffle significantly reduces the stagnant regions in the bed.

    摘要: In the conversion of methanol into ethylene, methanol is catalytically dehydrated and the ether product is converted into olefins at predetermined conversion over a zeolite catalyst. The zeolite catalyst is arranged as a plurality of beds with alternate cooling zones. The temperature rise in each bed is .not greater than the methanol to ethylene sensitivity parameter and each cooling zone reduces the temperature by the same amount. The total number of beds is at least equal to the ratio of total adiabatic temperature increase at the predetermined conversion to the sensitivity parameter.

    摘要: An improved process and apparatus are disclosed for fluidized catalytic cracking of hydrocarbons using a swirl type catalyst regenerator. Multiple, symmetrically spaced spent catalyst inlets are provided for addition of coked catalyst to the regenerator. Preferably, a single catalyst outlet, for withdrawal of regenerated catalyst, is provided in the center of the regenerator. Use of multiple symmetrical inlets and a central catalyst outlet greatly reduce stagnant regions in the bed.
