    摘要: The present invention is directed to a process for preparing zeolites belonging to the SSZ-26/33 family of zeolites using novel nitrogen-based structure directing agents. The process for preparing the SSZ-26/33 family of zeolites involves using a structure directing agent selected from the group consisting of 1,5-bis(N,N-dimethylcyclohexylammonium)pentane dications, 1,4-bis(N-cyclohexylpiperidinium)butane dications and 1,4-bis(N-cyclopentylpiperidinium)butane dications.

    摘要: An aluminosilicate ZSM-12 may be prepared de novo in a small crystalline form from a reaction mixture containing a source of silica and a source of alumina. A small crystalline form of aluminosilicate ZSM-12 may also be prepared from a small crystalline form of borosilicate ZSM-12 by replacement of boron in the borosilicate ZSM-12 framework with aluminum. The aluminosilicate ZSM-12 is useful as an isomerization selective catalyst in processes such as isomerization dewaxing hydrocarbon feedstocks.

    摘要: The present invention is directed to a borosilicate ZSM-48 molecular sieve having a mole ratio of between 40 and 400 of silicon oxide to boron oxide, synthesized using novel structure directing agents. Also disclosed are processes using a borosilicate ZSM-48 as a catalyst for the selective hydroconversion of heavy normal paraffins into lighter normal paraffin products, with minimal formation of isoparaffins.
