    • A catalytic cracking process is described in which methanol is a coreactant with gas oil in combination with a small amount (catalyst/oil 0.01) of a dispersed, very fine, and highly active catalyst powder, such as ZSM-5B. The methanol is preferably admixed with the catalyst before admixture with the oil in order to protect the catalyst from adsorption of poisonous compounds (e.g., nitrogenous compounds) during the initial stages of the reaction, particularly if the methanol is insoluble in a non-polar hydrocarbon feed. The premixed materials are fed into a riser reactor. The residence time in the reactor is 6-15 seconds. Preferably, the catalyst is not regenerated. The quantity of methanol is maintained so that its exothermic reaction is approximately heat balanced with the endothermic catalytic cracking reaction.
    • 描述了催化裂化方法，其中甲醇是与少量（催化剂/油0.01）的分散的，非常细的和高活性的催化剂粉末如ZSM-5B组合的助燃油的共反应物。 在与油混合之前，甲醇优选与催化剂混合，以便在反应的初始阶段保护催化剂免受有毒化合物（例如含氮化合物）的吸附，特别是如果甲醇不溶于非极性烃 饲料。 将预混材料进料到提升管反应器中。 反应器中的停留时间为6-15秒。 优选地，催化剂不再生。 维持甲醇的量，使其放热反应与吸热催化裂化反应近似热平衡。

    • A hydroprocessing trickle reactor construction which will facilitate the catalytic dewaxing of liquid petroleum or lube feedstocks in a highly efficient and economical manner, particularly through the use of reactors employing stationary bed of a defined, shape-selective crystalline aluminosilicate zeolite catalyst, preferably ZSM-5. Pursuant to one embodiment of the hydroprocessing reactor, the latter is essentially constituted of a trickle bed reactor wherein a plurality of vertically tiered and staggered trays support the beds of catalyst material, such as the crystalline zeolite, and through which the liquid petroleum feedstock trickles downwardly from the upper end of the reactor, while hydrogen is concurrently injected into the catalyst on each of the trays. This causes the hydrogen to percolate through the catalyst bed and to contact and efficiently strip the downwardly trickling stream of liquid petroleum feedstock of low boiling conversion products or waxy components, such as naphtha. Pursuant to a second embodiment of the hydroprocessing catalystic reactor construction, inclined supporting stationary beds of catalyst are vertically tiered with the liquid petroleum stock trickling down through the reactor so as to enter the upper portion of the bed contained in each tray, flowing along the inclined tray surface thereof forming a liquid seal along the bottom surface of each tray and forcing hydrogen introduced into each tray to flow upwardly through the catalyst bed and react with the liquid petroleum feedstock. The liquid is directed to trickle downwardly to a lower catalyst bed through the interposition of suitable baffles, whereas hydrogen gas inclusive of low boiling, volatile conversion products stripped from the liquid petroleum in the catalyst beds flows upwardly through passages beneath the baffles into a central vertical conduit in the reactor, from when they are conducted by being entrained in an upwardly-flowing carrier gas out of the upper end of the reactor.

    • 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。
