摘要： A fixed-sulfur, solid fuel product is obtained by an improved coking process wherein petroleum fractions are coked in the presence of added alkaline earth metal oxides. The fixed-sulfur, solid fuel product comprises coke and from about 3 to 30 weight percent, preferably from about 5 to 15 weight percent, "ash" (calculated as calcium oxide) derived from the alkaline earth additive. The quantity alkaline earth metal oxide or precursor thereof added to the coking zone is dependent on the sulfur content of the product coke and on the desired ash content of the solid fuel product. The coking zone may comprise delayed, fluid bed, or moving bed cokers.

摘要： The acidity of a zeolite catalyst is reduced by calcination in an essentially water-free atmosphere at temperatures above 700.degree. C., preferably from 725.degree. to 800.degree. C., to reduce the alpha value to less than about 10 percent of its original value. The low acidity catalysts produced in this way may be used for conversions requiring low acidity, shape selective catalysis, including dewaxing. The calcined, low acidity catalysts exhibit improved dewaxing activity.

摘要： A delayed coking process in which part of the coke produced is heated by partial burning and mixed with preheated coker feedstock to raise the temperature of the coking mass present in the coking drums. The rapid heat transfer thus obtained brings about some immediate flashing of volatiles and makes possible higher than usual temperatures in the coking drums. The results are a reduction of residence time in the drums and an increase in the yield of volatile products. Hot coke in excess of that required to heat the feed may be gasified. Thus, resultant net coke yields are lower than the conventional delayed coking process.
摘要翻译：延迟焦化方法，其中产生的焦炭的一部分通过部分燃烧加热并与预热的焦化器原料混合，以提高存在于焦化鼓中的焦化物质的温度。如此获得的快速热传递导致挥发物的一些即时闪蒸，并且使得可能比焦化鼓中的通常温度高。结果是减少了在鼓中的停留时间和挥发性产物的产率的增加。超过加热进料所需热焦炭可能气化。因此，得到的净焦炭产量低于常规的延迟焦化方法。

摘要： 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.
