  • SELECTIVE HYDROCRACKING OF NORMAL PARAFFIN
    Publication number: 20240059986
    Abstract: Provided is a process for hydrocracking normal paraffins into lighter normal paraffins with minimal formation of iso-paraffins. The process comprises hydrocracking a hydrocarbon feedstock comprising normal paraffins under hydrocracking conditions. The reaction is run in the presence of a specific type of zeolite based catalyst which has been found to provide high conversion with minimal iso-paraffin products. In one embodiment, the zeolite is of the framework PWO. The reaction conducted in the presence of the zeolite based catalyst produces an n-paraffin rich product that needs no separation step before being fed to a steam cracker to produce lower olefins.

  • METHODS TO PRODUCE MOLECULAR SIEVES WITH LTA TOPOLOGY AND COMPOSITIONS DERIVED THEREFROM
    Publication number: 20160263562
    Abstract: The present disclosure is directed to processing for preparing crystalline pure-silica and heteroatom-substituted LTA frameworks in fluoride media using a simple organic structure-directing agent (OSDA), having a structure of Formula (I): where substituents R1 to R9 are defined herein. Aluminosilicate LTA is an active catalyst for the methanol to olefins reaction with higher product selectivities to butenes as well as C5 and C6 products than the commercialized catalysts. Titanosilicate LTA is an active catalyst for the epoxidation of allyl alcohol using aqueous H2O2.
