摘要
重油中所含的金属在重油催化裂化过程中,会污染催化剂,导致催化剂失活。为延长催化裂化催化剂使用寿命,提高装置的轻收,降低生焦,某重油催化裂化装置选用HC-10金属钝化剂,并对其进行了工业实验。结果表明,在渣油掺炼比与原料总硫含量可比的条件下,使用钝化剂后干气中氢甲烷比呈下降趋势,产品分布中液收率上升,焦炭产率下降。
During heavy oil catalytic cracking,the metal contained in heavy can pollute catalyst and caused catalystdeactivation. To extend the service of catalytic cracking catalyst,improve the light oil yield,and reduce coke production,aheavy oil catalytic cracking unit selected HC- 10 metal catalyst,and made industrial experiment to it. The result showedthat,under the condition of comparable residue blending ratio and feedstock＇s total sulfur content,the hydrogen/methaneratio shows decline trend,the liquid yield in the production distribution goes up,and the coke yield goes down.
