英文摘要	the aromatization of light alkenes in liquefied petroleum gas (lpg) with and without dimethyl ether (dme) addition in the feed was investigated on a modified zsm-5 catalyst. the results showed that under the given reaction conditions the selectivity of alkenes to high-octane gasoline blending components was markedly enhanced and the formation of propane and butanes was greatly suppressed with the addition of dme. it was also found that the distribution of c5+ components was changed a lot with dme addition into the lpg feed. the formation of branched hydrocarbons (mainly c-6-c-8 i-paraffin) and multi-methyl substituted aromatics, which are high octane number gasoline blending components, was promoted significantly, while the content of n-paraffins and olefins in c5+ components was decreased obviously, indicating that in addition to the oligomerization, cracking, hydrogen-transfer and dehydrogenation-cyclization of alkenes, the methylation of the formed aromatics and olefins intermediates also plays an important role in determining the product distribution due to the high reactivity of surface methoxy groups formed by dme. and this process, in combination with the syngas-to-methanol/dme technology, provides an alternative way to the production of high-octane gasoline from coal, natural gas or renewable raw materials.
