摘要： Heavy hydrocarbon oils of high paraffin content are catalytically cracked using zeolite beta. The paraffin content of the oil is at least 20 weight percent or higher. The gasoline cracking products have a high octane rating and the higher boiling products a decreased pour point resulting from the dewaxing activity of the zeolite beta. The use of cracking temperatures above 500.degree. C., preferably above 550.degree. C., also improves iso-butene production.

摘要： Heavy oils are simultaneously subjected to cracking and dewaxing in the absence of added hydrogen using a catalyst comprising Zeolite Beta and an X or Y or other faujasite zeolite. The process is able to effect a bulk conversion of the oil, while, at the same time, yielding a higher octane gasoline, increased yields of C.sub.3 and C.sub.4 olefins, and a low pour point distillate product.

摘要： Dewaxing, preferably catalytic dewaxing over zeolite beta or ZSM-5, improves the crackability of a heavy, waxy feed to a catalytic cracking unit. When the catalytic dewaxing occurs at temperatures above about 360.degree. C., using ZSM-5 dewaxing catalyst, high octane gasoline is obtained as a by product of catalytic dewaxing.

摘要： 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.
摘要翻译：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。

摘要： A method for improving the cetane number of an aromatic hydrocarbon oil such as FCC light cycle oil and thereby increase its value as a blending stock for diesel fuel or heating oil. In one embodiment, the FCC light cycle oil is alkylated in the presence of a solid acidic catalyst and with a linear mono-olefin having a chain length of at least five carbon atoms. In another embodiment, the light cycle oil is alkylated with an olefin having three to nine carbon atoms or a mixture thereof and with ZSM-20 as catalyst to decrease the frequency of catalyst regeneration.

摘要： Dewaxing a waxy feedstock is achieved by submerging the dewaxing catalyst bed in the waxy feedstock and removing gaseous products out of contact with the catalyst by agitating the bed to prevent further cracking or polymerization. Catalyst aging during dewaxing is significantly reduced by operating the dewaxing reactor within a narrow low temperature range.
