    摘要： A catalytic process is provided for cracking a hydrocarbon charge stock containing aromatic nuclei components and non-aromatic nuclei components which involves contacting such chargestock with a catalyst composition having an alkali metal content less than about 1.5 weight percent and containing a mixture of faujasite and mordenite in which contacting takes place under catalytic cracking conditions of such severity that the conversion level exceeds that attributable to conversion of the non-aromatic nuclei portion of the chargestock. Under such conditions, the coke yield is substantially lower than would be obtained with the same catalyst in the absence of mordenite at the same level of conversion.

    摘要： This invention is directed to the shape selective conversion of a hydrocarbon charge over erionite which has been activated by the steps comprising calcining the erionite as a first step, contacting with a solution of an ammonium salt, contacting with a solution of metal salt containing a metal such as calcium, calcining again, contacting again with a solution of an ammonium salt and then with a solution of a metal salt containing nickel or another similar metal, and finally calcining. It is also directed to the catalyst utilized in affecting said conversion and to the method for preparing such catalyst.

    摘要： An improved moving bed continuous catalytic cracking process for cracking hydrocarbon feedstocks, such as gas oil, in the absence of added hydrogen, which includes the use of a minute amount of dispersed platinum supported directly on a cracking catalyst. The trace of platinum induces a substantial increase in the heat efficiency with which coke on catalyst is converted to CO.sub.2 in the regenerator section with minimal or no detriment to the cracking reaction.
