Abstract: Acidic halides, especially chlorides, are removed from a dry fluid stream by contact with dry particles of solid caustic. The solid caustic particles are preferably non-porous, and disposed as a fluidized bed. Salts deposit on the surface of the caustic and are physically removed, preferably by attrition, to regenerate the surface of the solid caustic. An dry, slightly alkaline salt can be the only product of neutralization. Salt coated beds of solid caustic can also be regenerated for reuse by attrition removal of salt deposits.

Abstract: Acidic halides, especially chlorides, are removed from liquid hydrocarbons such as catalytic reformate by contact with solid caustic such as a bed of NaOH pellets covered with a thin film of brine. Hydration of reformate improves removal when large amounts of chlorides are present in reformate. Halides in liquid hydrocarbon are recovered as a brine phase, which can be only slightly alkaline. Hydration of reformate can be controlled based on pH of brine removed from the bed.

Abstract: At least one olefin and at least one isoparaffin are converted to a diesel fuel blending component by contacting the olefin and the isoparaffin with a catalyst selected from MCM-22, MCM-36, MCM-49, and MCM-56 to provide a product containing a diesel fuel.

Abstract: A process is disclosed for alkylating an isoparaffin with an olefin comprising the steps of:(a) reacting an isoparaffin having from 4 to 8 carbon atoms with an olefin having from 2 to 12 carbon atoms in a first alkylation reaction stage at temperature from about -40.degree. C. to about 500.degree. C. and overall isoparaffin:olefin feed weight ratio of from about 1:1 to about 250:1 with a solid alkylation catalyst comprising a synthetic porous crystalline material characterized by an X-ray diffraction pattern including values substantially as set forth in Table I of the specification and having a composition comprising the molar relationshipX.sub.2 O.sub.3 :(n)YO.sub.

Abstract: Acidic halides, especially chlorides, in two phase (vapor and hydrocarbon liquid) reactor effluent are separated and at least the halides in the vapor fraction neutralized in a vapor/liquid separator with an alkaline neutralization medium such as an alumina treater impregnated with NaOH. The treater may remove halides from both the vapor and liquid phase within the separator.

Abstract: Acidic halides, especially chlorides, are removed from dry process vapor and liquid hydrocarbon streams by contact with solid caustic, such as a bed of NaOH. Salt deposits from form on the solid caustic, which are periodically removed by passing a liquid hydrocarbon continuous phase containing a minor amount of dissolved or entrained water over the solid caustic. Salts may be removed from the liquid hydrocarbon by extraction with water, which also saturates the liquid hydrocarbon so that it may be used to remove additional salt deposits.

Abstract: There is provided a process for increasing the Cetane Index of a distillate fraction by reacting the fraction with hydrogen over a catalyst comprising a hydrogenation component, such as platinum, and zeolite Beta. The process results in the selective ring opening of cyclic compounds, such as aromatics, with a minimum of cracking of paraffinic hydrocarbons.
