We report on the effect of butane and butylene on hydrogen permeation through thin state-of-the-art Pd–Ag alloy membranes. A wide range of operating conditions, such as temperature (200–450 °C) and H2/butylene (or butane) ratio (0.5–3), on the flux-reducing tendency were investigated.

Propane and butane are short straight-chain alkane molecules that are difficult to convert catalytically. Analogous to propane, butane can be dehydrogenated to butenes (also known as butylenes) or butadiene, which are used industrially as raw materials when synthesizing various chemicals (plastics, rubbers, etc.).


In this study, we present results of detailed first-principles-based multiscale modelling of butane dehydrogenation, which can be paralleled to experimental data.
We found that among all the dehydrogenation products 2-butene (CH3CHCHCH3) is the most abundant product of dehydrogenation, with selectivity above 90%, concluding that the dehydrogenation of butane is a viable alternative to conventional olefin production processes.
