    摘要： The operation of FCC apparatus is improved by decreasing oil partial pressure in the FCC reactor riser by about 10 psia, as compared to the normal oil partial pressure in the riser, thereby increasing octane rating of the gasoline produced in the FCC unit. The oil partial pressure may be reduced by injecting a suitable amount of an inert diluent into the riser, or by decreasing throughput of the FCC reactor.

    摘要： A fluid catalytic cracking (FCC) process and apparatus using a riser and a reactor for cracking of petroleum feeds in the presence of a catalyst and a regenerator for regenerating the spent catalyst are improved by providing a downflow riser. The downflow riser assures uniform distribution of the catalyst throughout the feed, decreases contact time of the catalyst with the feed and decreases the amount of coke made in the process.

    摘要： In a fluid catalytic cracking (FCC) process and apparatus, the heat balance between the reactor and the regenerator of the FCC operation is partially uncoupled by transferring at least a portion of thermal energy from the reactor vessel downflow riser to the regenerator vessel. The transfer of thermal energy results in a higher regenerating temperature. The thermal energy is recirculated to the upstream section of the downflow reactor riser through a regenerated catalyst having higher temperature. Consequently, the outlet of the reactor vessel is maintained at a substantially constant temperature (e.g., 1000.degree. F.) and the rate of conversion of the oil feed and the octane number of gasoline produced in the process are increased.

    摘要： In the fluid catalytic cracking process, improved adaptive behavior of the catalyst section with the regenerator operating in the complete CO-burning mode is achieved by including, as elements of control, variable preheat of the oil feed and variable recycle of regenerated catalyst to spent catalyst. In response to excursions of the regenerated catalyst temperature, such as would be caused by change of feedstock, the oil preheat temperature and recycle ratio are altered in a direction to restore the regenerated catalyst temperature to a predetermined value. The improved control system extends the useful control range, and it also diminishes counterproductive changes in severity induced by disturbances such as change of feedstock quality.

    摘要： In the fluid catalytic cracking process, improved adaptive behavior of the catalyst section with the regenerator operating in the complete CO-burning mode is achieved by including, as elements of control, variable preheat of the air feed and variable recycle of regenerated catalyst to spent catalyst. In response to excursions of the regenerated catalyst temperature, such as would be caused by change of feedstock, the air preheat temperature and recycle ratio are altered in a direction to restore the regenerated catalyst temperature to a predetermined value. The improved control system extends the useful control range, and it also diminishes counterproductive changes in severity induced by disturbances such as change of feedstock quality.

    摘要： Heavy petroleum oils such as resids are subjected to visbreaking in the presence of a hydroaromatic hydrogen donor solvent having an aromatic and alpha-to-aromatic proton content each of at least 20 percent of the total solvent hydrogen. The amount of donor solvent is from 0.1 to 50, preferably 0.1 to 20, weight percent of the heavy oil feed. The visbreaking may be carried out at relatively high severities as the use of the donor solvent reduces coke formation as well as producing a product of reduced viscosity, pour point and sedimentation characteristics. Reaction severity is usually in the range of 250 to 1500 seconds ERT at 800.degree. F. (427.degree. C.) but may range up to 15000 seconds ERT. Suitable solvents may be obtained from catalytic cracking process, for example, FCC cycle oils, slurry oils and main column bottoms.

    摘要翻译： 在油芳族氢供体溶剂存在下，将重质石油油（如残渣）进行减粘裂化，其具有芳族和α-至芳族质子含量，每个都占总溶剂氢的至少20％。 供体溶剂的量为重油进料的0.1-50重量％，优选0.1-20重量％。 减粘裂化可以在相当高的严重程度下进行，因为使用供体溶剂减少焦炭形成，以及生产具有降低粘度，倾点和沉降特性的产物。 反应严重度通常在800°F（427°C）的250至1500秒的ERT范围内，但可能范围高达15000秒ERT。 合适的溶剂可以从催化裂化过程获得，例如FCC循环油，浆料油和主塔底物。
