    摘要： The catalyst exhibiting hydrogen spillover effect relates to the composition of a catalyst exhibiting hydrogen spillover effect and to a process for preparing the catalyst. The catalyst has a reduced transition base metal of Group VIB or Group VIIIB, such as cobalt, nickel, molybdenum or tungsten, supported on a high porous carrier, such as saponite, the base metal being ion-exchanged with at least one precious metal of Group VIIIB. The process includes the steps of loading the base metal onto the support, reducing the base metal, preferably with H2 at 600° C., and thereafter ion-exchanging the precious metal with the base metal. Preferred examples of the catalyst include a saponite support loaded with about 10-20 wt % cobalt and about 0.1-1 wt % precious metal. The catalyst is optimized for reactions that occur in commercial processes at about 360-400° C., such as in hydrocracking.

    摘要： The system and method for conversion of molecular weights of fluids includes an elongate metallic pipe. A fluid is caused to flow through the pipe. A center electrode is mounted within the pipe coaxially with the pipe axis and the flow direction, the electrode being insulated from the pipe wall. The center electrode and the pipe wall are connected to the terminals of a voltage source to create an electric field extending radially between the center electrode and the pipe wall. A source of gamma radiation positioned either within the center electrode or external to the pipe directs gamma rays transverse to the direction of fluid flow. The combined radiation and electric field disrupts chemical bonds, creating ionization zones and resulting in the formation of lower-molecular-weight compounds. Optionally, a magnetic field may be superimposed in the direction of fluid flow.

    摘要： This invention concerns an improved and novel catalyst for preparing methyl tertiary butyl ether (MTBE). This invention is advantageous in that the reaction of methanol and isobutene takes place such that the catalysts exhibit levels of isobutene conversion as high as 98%, and the MTBE selectivity reaches as high as 98%. The improved catalysts comprises of a crystalline aluminosilicate zeolites, particularly MFI-type zeolites which has been treated with aluminum fluoride in the ratio 1 gram to 10 grams of zeolite with 0.5 gram to 5 grams of aluminum fluoride. A specific application of this improved and novel catalyst is reacting methanol and isobutene in a molar amount of about 0.1 mole to 10 moles of methanol per mole of isobutene, in the presence of said catalyst in a batch reactor, at about 70° C. to about 100° C., and a pressure of about 1 bar to 33 bar, to obtain MTBE product.
