    摘要: A three-step process of removing sulfur from naphtha feeds. The steps include a first hydrotreating step, a mercaptan removal agent and an adsorbent containing a reactive metal on an inorganic support. Step one removes at least 95 wt. % of the sulfur compounds while preserving at least 50 wt. % of the olefins. Treatment with the mercaptan removal agent lowers the sulfur content to 30 wppm total sulfur and final naphtha product contains leas than 10 wppm total sulfur.

    摘要: The invention relates to a process for forming a low-sulfur motor gasoline and the product made therefrom. In one embodiment, process involves separating a catalytically cracked naphtha into at least a light fraction boiling below about 165° F. and a heavy fraction boiling above about 165° F. The light fraction is treated to remove sulfur by a non-hydrotreating method, and the heavy fraction is hydrotreated to remove sulfur to a level of less than about 100 ppm.

    摘要: A process for producing polymers from olefins selectively produced from a catalytically cracked or thermally cracked naphtha stream is disclosed herein. The naphtha feedstream is contacted in the reaction zone with a catalyst under catalytic conversion concditions. Vapor products are collected overhead and the catalyst particles are passed through the stripping zone on the way to the catalyst regeneration zone. Volatiles are stripped with steam in the stripping zone and the catalyst particles are sent to the catalyst regeneration zone where coke is burned from the catalyst, which is then recycled to the reaction zone. A stream rich in C4 and/or C5 olefins is recycled to the stripping zone.

    摘要: A process for producing ultra clean distillate and naphtha products wherein a distillate boiling range stream which contains heteroatoms and aromatics to subjected to three stage processing. The first stage is conventional hydrotreating, wherein the resulting effluent is further hydrotreated, but with a noble metal zeolite catalyst which is typically used for hydrocracking. The effluent from this second stage, which is now substantially free of heteroatoms, is passed to a third stage. This third stage is a hydrocracking stage, the severity of which will determine if the ultimate product will be a distillate or a naphtha.

    摘要: A method for passivating metal contaminants present in a hydrocarbon feedstock which become deposited on cracking catalyst is described. The method is directed at passing the cracking catalyst through a passivation zone having a reducing atmosphere maintained at an elevated temperature. The reducing atmosphere comprises a process reducing gas stream which has been passed through a guard bed adapted to selectively remove an unsaturated hydrocarbon prior to the process reducing gas being added to the passivation zone.

    摘要: A method for passivating a catalyst used to crack hydrocarbon feedstock to lower molecular weight products in a reaction zone is disclosed where the feedstock contains at least one metal contaminant selected from the class consisting of nickel, vanadium and iron and where the contaminant becomes deposited on the catalyst such that at least a major portion of the total of said metal contaminant deposited on the catalyst comprises only one of the metal contaminants. The method comprises monitoring the composition of said metal contaminant on the catalyst, adding a predetermined amount of at least one of said metal contaminants not present as the major contaminant on the catalyst, and passing the catalyst from the reaction zone through a reduction zone maintained at an elevated temperature for a time sufficient to at least partially passivate said metal contaminant.CROSS-REFERENCE TO RELATED APPLICATIONSThis application is related to U.S. Patent Application, Ser.
