    摘要: A substantially water-free hydrocarbon feed is charged to a reformer reactor operated under reforming conditions; thereafter, a chlorine-containing additive is introduced, without the simultaneous introduction of water, into the substantially water-free hydrocarbon feed being charged to the reformer reactor in an amount and for a time period that are effective to inhibit deactivation of the reformer catalyst; thereafter, the introduction of the chlorine-containing additive is terminated and the charging of the substantially water-free hydrocarbon feed to the reformer reactor is continued.

    摘要: Catalyst activation of a platinum reforming catalyst system contained in a multiple reactor system by simultaneously reducing the catalyst with a sustained hydrogen flow through the multiple reactor system while introducing a nonmetallic chlorine-containing compound serially into each reactor of the multiple reactor system in an amount to add from about 0.05 to about 0.3 weight percent chlorine to the catalyst and thereafter purging the system with about 100 to about 50,000 cubic feet of hydrogen per cubic foot of catalyst prior to commencing use of the treated catalyst system for reforming hydrocarbon feed.

    摘要: Catalyst life in desulfurization of distillate hydrocarbon streams is predicted with the aid of a computer simulation which embodies an analytical kinetic model of a hydrodesulfurization reaction and a semi-empirical model for catalyst deactivation. The simulation specifies the decline of catalyst activity with time and a current reaction temperature required to maintain the initial catalyst activity. The useful life of the catalyst is considered to be the time required for catalyst activity in the simulated reaction to decline sufficiently from its initial level so that a predefined maximum reaction temperature is reached while maintaining a desired level of sulfur in the desulfurized product. The computer time needed to simulate the reaction is decreased by combining superior features of LOTUS 1-2-3 and FORTRAN language, such that input/output and graphic operations are implemented with LOTUS 1-2-3 and numerical calculations are executed in FORTRAN.

    摘要: A reforming catalyst containing a Group VIII metal, or a Group VII B metal, or tin, or germanium, or copper, or selenium or combinations of any two or more metals or oxides thereof is activated by: a) continuously flowing a reducing gas over the catalyst for contact with the catalyst; (b) during step a), flowing a halogen-containing compound over the catalyst for contact with the catalyst for a first time period, wherein the first time period is greater than about 1 minute, and wherein the first time period is less than about 60 minutes; and (c) following step b), and during step a), substantially discontinuing the flow of the halogen-containing compound over the catalyst for a second time period, wherein the second time period is greater than about 1 minute. Alternatively, the catalyst can be activated in an activation zone by: 1) removing water from the activation zone; 2) reducing iron oxide contained in the activation zone in the presence of a reducing gas thereby forming reduced iron and water; 3) removing water from the activation zone; 4) reducing the metal oxide of the catalyst in the presence of a reducing gas thereby forming reduced metal and water; 5) removing water from the activation zone; 6) during step 4), flowing a halogen-containing compound over the catalyst for contact with the catalyst for a first time period; and 7) following step 6) and during step 4), substantially discontinuing the flow of halogen-containing compound over the catalyst for a second time period.
