Abstract
A novel method for co-conversion of alkane with another reactant over zeolite catalysts for alkane transformation is presented. With the aid of solid-state NMR spectroscopy and GC-MS analysis, researchers observed that the co-conversion of propane and methanol can be readily initiated by hydride transfer at temperatures of ≥449 K over the acidic zeolite H-ZSM-5.
The formation of 13C-labeled methane and singly 13C-labeled n-butanes in selective labeling experiments offered the first evidence for the initial hydride transfer from propane to surface methoxy intermediates. Results offer insight into carbocation chemistry of solid acids. They also shed light on the low-temperature transformation of alkanes for industrial applications.
