摘要： A catalytic cracking process especially useful for the catalytic cracking of high metals content feeds including resids in which the feed is cracked in the presence of a catalyst additive comprising a dehydrated magnesium-aluminum hydrotalcite which acts as a trap for vanadium as well as an agent for reducing the content of sulfur oxides in the regenerator flue gas. The additive is used in the form of a separate additive from the cracking catalyst particles in order to keep the vanadium away from the cracking catalyst and so preserve the activity of the catalyst.

摘要： An improved composition and method for passivating vanadium on or in a catalytic cracking catalyst during the process of catalytic cracking of hydrocarbons is described. The improved method comprises mixing discrete particles of lanthanum oxide and, optionally, other rare earth oxides along with the catalyst and the hydrocarbon during the catalytic cracking process.

摘要： A catalytic cracking process especially useful for the catalytic cracking of high metals content feeds including resids in which the feed is cracked in the presence of a catalyst additive comprising an alkaline earth metal oxide and an alkaline earth metal spinel, preferably a magnesium aluminate spinel which acts as a trap for vanadium as well as an agent for reducing the content of sulfur oxides in the regenerator flue gas. The additive is used in the form of a separate additive from the cracking catalyst particles in order to keep the vanadium away from the cracking catalyst and so preserve the activity of the catalyst; in addition, use of separate additive particles permits the makeup rate for the additive to be varied relative to that of the cracking catalyst in order to deal with variations in the metals and sulfur content of the cracking feed. The additive may be separated from the cracking catalyst by physical classification so that it can be separately withdrawn from the unit for better control of the catalyst/additive ratio. The additive may be injected into the unit separate from the cracking catalyst so that it contacts the feed first to effect a preliminary demetallation.
摘要翻译： 催化裂解方法特别适用于高金属含量进料的催化裂化，包括在催化剂添加剂存在下进料裂化的残渣，所述催化剂添加剂包含碱土金属氧化物和碱土金属尖晶石，优选铝酸镁尖晶石，其作用 作为钒的捕集剂以及用于降低再生器烟道气中的硫氧化物含量的试剂。 添加剂以与裂化催化剂颗粒不同的添加剂的形式使用，以使钒远离裂化催化剂，因此保持催化剂的活性; 此外，使用单独的添加剂颗粒允许添加剂的补充比率相对于裂化催化剂的补充速率变化，以便处理裂化原料的金属和硫含量的变化。 添加剂可以通过物理分级与裂化催化剂分离，从而可以单独从单元中取出，以更好地控制催化剂/添加剂比例。 可以将添加剂注入到与裂化催化剂分离的单元中，使得其首先接触进料以进行初步脱金属。

摘要： Low sulfur gasoline of relatively high octane number is produced from a catalytically cracked, sulfur-containing naphtha by hydrodesulfurization followed by treatment over an acidic catalyst containing, preferably an intermediate pore size zeolite such as ZSM-5 and a zeolite such as MCM-22. The treatment over the acidic catalyst in the second step restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha. In favorable cases, using feeds of extended end point such as heavy naphthas with 95 percent points above about 380.degree. F. (about 193.degree. C.), improvements in both product octane and yield relative to the feed may be obtained.

摘要： Low sulfur gasoline of relatively high octane number is produced from a cracked, sulfur-containing olefinic naphthas by hydrodesulfurization followed by treatment over an acidic catalyst comprising zeolite beta with a metal hydrogenation component, preferably a mild hydrogenation component such as molybdenum. The treatment over the acidic catalyst in the second step restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha. In favorable cases, using feeds of extended end point such as heavy naphthas with 95 percent points above about 380.degree. F. (about 193.degree. C.), improvements in both product octane and yield relative to the feed may be obtained.

摘要： Low sulfur gasoline of relatively high octane number is produced from a catalytically cracked, sulfur-containing naphtha and benzene-rich fraction by hydrodesulfurization in a first reaction zone and treatment over an acidic catalyst, preferably an intermediate pore size zeolite such as ZSM-5 in a second reaction zone to reduce the octane loss which takes place as a result of the hydrodesulfurization. The benzene-rich fraction can be cofed to the first reaction zone or the second reaction zone. The benzene-rich fraction is preferably a heart-cut reformate.

摘要： An FCC catalyst regeneration technique in which the catalyst is regenerated in a dense bed regenerator. Regenerator effluent gases are collected from different parts of the regenerator vessel in a common collection zone and passed through the catalyst separation cyclones from the common collection zone. Removal of nitrogen oxides from the regeneration effluent gases is enhanced by passing spent cracking catalyst through the effluent gases from a secondary spent catalyst inlet in the upper part of the regeneration vessel. Coke on the spent catalyst effects a reduction of nitrogen oxide (NOx) species in the effluent gases to nitrogen.

摘要： Low sulfur gasoline of relatively high octane number is produced from a catalytically cracked, sulfur-containing naphtha by hydrodesulfurization followed by treatment over an acidic catalyst under endothermic conditions in a second reaction zone. Heat is added to the endothermic reaction zone to initiate and maintain octane restoring reactions. The preferred acidic catalyst is an intermediate pore size zeolite such as ZSM-5. The treatment over the acidic catalyst in the second step restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha. The addition of heat at the second zone prolongs hydrodesulfurization catalyst life by allowing a lower hydrodesulfurization reactor temperature. The addition of heat also maximizes octane increase in the second zone.

摘要： Low sulfur gasoline of relatively high octane number is produced from a catalytically cracked, sulfur-containing naphtha by hydrodesulfurization followed by treatment over an acidic catalyst defined by its x-ray diffraction pattern and preferably comprising the synthetic zeolite MCM-22. The treatment over the acidic catalyst in the second step restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha. In favorable cases, using feeds of extended end point such as heavy naphthas with 95 percent points above about 380.degree. F. (about 193.degree. C.), improvements in both product octane and yield relative to the feed may be obtained.

摘要： Low sulfur gasoline of relatively high octane number is produced from a catalytically cracked, sulfur-containing naphtha by hydrodesulfurization followed by treatment over an acidic catalyst comprising a zeolite sorbing 10 to 40 mg 3-methylpentane at 90.degree. C., 90 torr, per gram dry zeolite in the hydrogen form, e.g., ZSM-22, ZSM-23, or ZSM-35. The treatment over the acidic catalyst in the second step restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha. The use of the specified zeolite provides greater desulfurization, gasoline selectivity, and octane than obtained using ZSM-5.
