Progress in Light Paraffin Isomerization

Light paraffin isomerization is an important method for processing and utilizing of natural gas liquid, it plays an important role in improving the octane number of light gasoline fractions. In the need of green chemical and clean fuel productions, this process is supposed to be of greater and greater importance. Consequently, the development of the technology was given great concern in oil refining and chemical industries, and great efforts were made to promote its achievement. In this paper, the progress of the technology was reviewed in aspects of process and catalyst, research achievements made in the recent years were summarized, and the developing trendency was analyzed. Light paraffin isomerization prefers low temperature operation. Some new catalysts, such as solid super acid catalysts and molecular sieve catalysts with newly developed catalytic materials, are well worth further investigating to achieve the high efficiency of the process.
