英文摘要: Oligomerization of butene-2 over HZSM-5 zeolite was carried out in a continuous flow fixed-bed reactor at 210-300 degrees C, 3-5 Mpa, and 0.5-1.5 h(-1) of LHSV. The results showed that the reactions of butene-2 over the HZSM-5 zeolite and the content of higher molecular weight olefins in liquid products were influenced by temperature, pressure, and space velocity. The product was dominantly olefins at the reaction temperatures below 300 degrees C, and the less branched structure of the product suggested shape-selective catalysis over HZSM-5. The acidity of the HZSM-5 zeolite influenced the activity and selectivity, and the zeolite with lower silica/alumina ratio enhanced the liquid yield and selectivity for higher olefins.
