大庆石化总厂炼油厂1000Kt／a重油催化裂化装置使用高效金属钝化剂，取得明显效果。经过20d标定表明，在平衡催化剂Ni含量为3500～3900μg／g，干气中H2含量为35％～40％的情况下，使用该剂后，干气中H2含量相对下降45％，轻油收率约对值提高了1．02个百分点，经济效益为830.6万元/a。
Daqing Petrochemical Plant refinery 1000Kt / a heavy oil catalytic cracking unit using efficient metal deactivator, and achieved significant results. After the 20d calibration, H2 content in dry gas decreased by 45% when the equilibrium catalyst Ni content was 3500-3900μg / g and the dry gas H2 content was 35% -40%. Light oil income The rate of value increased by 1.02 percentage points, the economic benefit of 8.36 million yuan / a.
