    摘要： A process for catalytic cracking, isomerizing of reforming of a hydrocarbon feed stock comprises the step of passing said hydrocarbon feed stock through a catalyst bed at cracking, isomerizing or reforming conditions to crack, isomerize or reform said hydrocarbon feed stock, wherein the catalyst composition in the catalyst bed, comprises a pillared fluorotetrasilicic mica, wherein said pillared fluorotetrasilicic mica has a specific surface area exceeding 75 m²/gm, wherein the mica is pillared by alumina, zirconia or chromia, and the aluminum, zirconium or chromium content is at least 8% by weight. In the catalytic cracking process, there is less carbon and hydrogen formed than in comparative processes, and the cracked product contains a relatively high proportion of C₃ and C₄ olefins.

    摘要： 4-methyl-1-pentene is produced via the catalyst dimerization of propylene.
    Using a catalyst comprising at least one element selected from uranium and the rare earth metals. The selectivity to 4-methyl-1-pentene usually is at least 94 mole percent. The preferred catalysts are uranium and rare earth di(poly-substituted cyclopentadienyl) hydride complexes especially uranium (pentahaptopenta methyl cyclopentadienyl) hydride complexes.

    摘要： A process for preparing 4-methyl-1-pentene comprising dimerizing propylene in the presence of a catalyst, characterized in that the catalyst is composed from the treatment of precatalyst by at least one oxygen-containing compound selected from oxygen, alcohols, ethers, acetals, orthocarboxylates and esters. The precatalyst is composed of element or compound selected from sodium, potassium, sodium amide and potassium amide supported on a carrier principally represented by the following formula (1):
    wherein x has a value in the range of 0.5≦
    The use of above mentioned catalyst so remarkably increases the rate of reaction and the selectivity of 4-methyl-1-pentene and allows the reaction rate and selectivity to be kept high for a long period of time.
