摘要:
采用浸渍法对流化催化裂化(FCC)中的增产丙烯助剂(LHP-A)进行了重金属钒、镍污染复配。考察了不同含量钒、镍单独或共同污染作用下对LHP-A的比表面积、相对结晶度和微反活性的影响,并分别在固定床微型反应评价装置(MAT)和先进的催化裂化评价装置(ACE)上评价了增产丙烯助剂相应污染复配后催化剂的反应性能。结果表明:无论LHP-A是否被重金属钒、镍单独或共同污染,只要FCC主催化剂复配了含质量分数10%的丙烯助剂后,丙烯收率均可提升4个百分点以上;在钒污染质量分数低于1%时,LHP-A具有良好的水热稳定性;当重金属镍污染LHP-A时,干气产率显著增加,但在钒污染量相同的前提下,镍的存在可以减缓钒对丙烯助剂性能的影响。
Abstract:
The heavy metal vanadium and nickel contamination were compounded by the impregnation method on LHP-A, an additive for increasing propylene production in fluid catalytic cracking(FCC). Then, the influence of different contents of vanadium and nickel on the specific surface area, relative crystallinity and micro-reactivity of LHP-A under the contamination condition of different contents of vanadium and nickel alone or together were studied, and the reaction performance of the catalyst was evaluated in the fixed bed micro reaction evaluation unit(MAT) and the advanced catalytic cracking evaluation unit(ACE) after the corresponding contamination of the additive for increasing propylene production. The results showed that: no matter whether LHP-A was contaminated by vanadium and nickel alone or together, the yield of propylene would increase by more than 4 percentage points, as long as the FCC main catalyst was combined with 10% propylene additive. When the mass fraction of vanadium contamination was less than 1%, LHP-A had good hydrothermal stability. When LHP-A was contaminated by the heavy metal nickel, the dry gas yield increased significantly, but under the premise of the same amount of vanadium contamination, the presence of nickel was able to slow down the influence of vanadium on the performance of propylene additives.
