    • An FCC or fluidized catalytic cracking process and apparatus for converting heavy metals laden crudes is disclosed. The heavy feed, conventional catalyst and an additive or vanadium getter contact the feed in a riser reactor. The additive is segregated from conventional FCC catalyst upstream of the conventional FCC regenerator. An elutriating, upflow riser reactor may be used with a coarse, rapidly settling getter. A fine, slowly settling getter may be used, with getter segregation achieved by using an elutriating cyclone on the riser outlet, an elutriating catalyst stripper, a sieve, or the like. The spent getter may be used once through, regenerated in a separate getter regenerator, or used as a source of fuel. Alumina and sponge coke are preferred getters.
    • 公开了一种FCC或流化催化裂化方法和用于转化重金属负载原油的装置。 重料,常规催化剂和添加剂或钒吸附剂在提升管反应器中接触进料。 该添加剂与常规FCC再生器上游的常规FCC催化剂分离。 淘汰式上升式提升管式反应器可与粗,快速沉降的吸气剂一起使用。 可以使用细的缓慢沉降的吸气剂,通过在提升管出口,淘洗催化剂汽提器,筛子等上使用淘洗旋风来实现吸气剂分离。 废吸气剂可以一次使用,在单独的吸气剂再生器中再生,或用作燃料来源。 氧化铝和海绵焦炭是优选的吸气剂。

    • An improved method which provides for an extended cycle length in catalytic lube dewaxing of residual lube oil feedstocks and easier catalyst regeneration. The method may incorporate catalytically dewaxing a feedstock in a fixed bed reactor with or without product recycle, or a series of reactors with interreactor separation of vapors from liquids. Improved performance is achieved by operating the reactor at a temperature between about 490.degree. and about 620.degree. F., employing a high activity crystalline zeolite catalyst having an alpha value between about 50 and about 900 based on the zeolite and a space velocity sufficiently low to produce a dewaxed effluent of desired pour point and to maintain an average catalyst aging rate of less than about 2.degree. F. per day. This relatively low temperature operation allows catalyst performance to be restored by simple hydrogen reactivation.
    • 一种改进的方法,其提供了在残余润滑油原料的催化润滑油脱蜡中延长的循环长度并且更容易的催化剂再生。 该方法可以将原料催化脱蜡在具有或不具有产物再循环的固定床反应器中,或者一系列具有蒸发器与液体的反应器分离的反应器。 通过使用基于沸石的α值在约50至约900之间的高活性结晶沸石催化剂,在约490℃至约620℃的温度下操作反应器来实现改进的性能,空间速度足够低至 产生所需倾点的脱蜡流出物,并保持每天平均催化剂老化速率小于约2°F。 这种相对较低的温度操作允许通过简单的氢再活化来恢复催化剂性能。
