    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.
