T-PHI C5/C6 isomerization technology

While increasing amount of global countries are proposing and advocating the concept of ‘Clean Gasoline’, the proportion of C5/C6 iso-alkane gasoline in market is growing rapidly. C5/C6 iso-alkane is a clean blend of gasoline with high octane number, aromatics free and olefin free. The main function of this technology is to form C5/C6 isomerized alkanes by catalyzing C5/C6 normal alkanes.

Suitable Feedstock

C5/C6 components in condensate, naphtha, reforming extractor, aromatics extractor and coal base naphtha
