TLDR
In this paper, the advances of pervaporative operation for gasoline desulfurization are reviewed and the selectivity and permeability with varying feed composition and operating parameters are analyzed.Abstract:
Worldwide concerns over the environment have stimulated increasing interest both in academic and industry for the deep desulfurization of gasoline. Due to some inherent disadvantages associated with the conventional hydrodesulfurization, several non-conventional techniques are being tried by researchers. Pervaporation is such a recently developed technology for gasoline desulfurization. Its efficiency has attracted worldwide attention. Compared with conventional sulfur removal technology for gasoline, pervaporation exhibits advantages of little reduction of octane number, low energy consumption, environmental benefits, simple operation, and easy scale-up. The advances of pervaporative operation for gasoline desulfurization are reviewed in this paper. The membrane materials used for desulfurization include polysiloxane, poly(ethylene glycol), polyimide, polyurethane and organic-inorganic hybrid membranes. Analysis of the selectivity–permeability with varying feed composition and operating parameters are in...read more

TL;DR: In this article, the tradeoff relation between membrane separation performance and swelling resistance is another great challenge, which significantly restricts the application efficiency of all membrane processes, and the ubiquitous tradeoff relationship between membrane separability and swelling resiliency is also a great challenge other than the trade-off relations between membrane permeability and selectivity.
