摘要： An oxygenate conversion catalyst useful in the conversion of oxygenates such as methanol to olefinic products may be improved by the use of a catalyst combination based on a molecular sieve in combination with a co-catalyst comprising a mixed metal oxide composition which has oxidation/reduction functionality under the conditions of the conversion. This metal oxide co-catalyst component will comprise a mixed oxide of one or more, preferably at least two, transition metals, usually of Series 4, 5 or 6 of the Periodic Table, with the metals of Series 4 being preferred, as an essential component of the mixed oxide composition. The preferred transition metals are those of Groups 5, especially titanium and vanadium, Group 6, especially chromium or molybdenum, Group 7, especially manganese and Group 8, especially cobalt or nickel. Other metal oxides may also be present. The preferred molecular sieve components in these catalysts are the high silica zeolites and the SAPOs, especially the small pore SAPOs (8-membered rings), such as SAPO-34. These catalyst combinations exhibit reduced coke selectivity have the potential of achieving extended catalyst life. In addition, these catalysts have the capability of selectively converting the hydrogen produced during the conversion to liquid products, mainly water, reducing the demand on reactor volume and product handling.

The catalyst comprises a first molecular sieve having an intermediate pore size, a second molecular sieve and, optionally a third molecular sieve having a large pore size. At least one of the channels of the second molecular sieve has a pore size index that is less than the pore size index of at least one channel of the first molecular sieve. The process is carried out by contacting a feedstock containing hydrocarbons having at least 5 carbon atoms is contacted, under catalytic cracking conditions, with the multi component catalyst. The catalyst finds application in the cracking of naphtha and heavy hydrocarbon feedstocks.

摘要： In a process for producing cyclohexylbenzene, benzene is contacted with hydrogen under hydroalkylation conditions effective to form a first effluent stream comprising cyclohexylbenzene, cyclohexane, methylcyclopentane, and unreacted benzene. At least a portion of the first effluent stream is contacted with a dehydrogenation catalyst under dehydrogenation conditions to convert at least a portion of the cyclohexane to benzene thereby forming a second effluent stream. The amount of methylcyclopentane in the second effluent stream is different by no more than 65% of the total amount of the portion of the first effluent stream, said amounts being on a weight basis. A methylcyclopentane-containing stream is removed from either the first or the second effluent stream and at least a portion of the second effluent stream containing benzene is recycled to the hydroalkylation step.

摘要： The invention relates to hydroalkylation processes. In the processes, a hydrogen stream comprising hydrogen and an impurity is treated to reduce the amount of the impurity in the hydrogen stream. The hydrogen is then hydroalkylated with benzene to form at least some cyclohexylbenzene. The processes also relate to treating a benzene stream comprising benzene and an impurity with an adsorbent to reduce the amount of the impurity in the benzene stream. The hydroalkylation processes described herein may be used as part of a process to make phenol.
