| Abstract: | Catalytic cracking of 1-butene to propene and ethene was investigated using HMCM-49 zeolite as catalyst by changing the effect of reaction condition on the reaction performance.As result,proper reaction condition can suppress secondary reaction effectively and improve the total selectivity of propene and ethene.When the WHSV is 9.4 h-1,1-butene partial pressure is 0.04 MPa,the temperature is 580 ℃,the total selectivity and yield of propene and ethene achieved 79.6% and 58.5%,respectively. |
