摘要： An improved fluidized bed process for upgrading olefinic hydrocarbon feedstock by contacting the feedstock with acidic siliceous zeolite conversion catalyst particles at elevated temperature under exothermic conditions to produce heavier hydrocarbons including gasoline range hydrocarbons. The improvement comprises maintaining a turbulent fluidized bed of catalyst particles by flowing hydrocarbon-containing vapor upwardly through said bed at less than transport velocity; and introducing liquid olefinic feedstock comprising at least one C.sub.4 -C.sub.6 diene component into the fluidized catalyst bed in a lower portion thereof by rapidly atomizing and vaporizing the liquid feedstock, thus converting feedstock to heavier hydrocarbon without substantial thermal diene degradation thereof prior to contacting conversion catalyst particles in the fluidized bed. A predominantly liquid product is recovered containing C.sub.4 -C.sub.9 hydrocarbons rich in olefins and aromatics.

摘要： A technique for continuous conversion of diene-containing aliphatic hydrocarbon feedstock to heavier hydrocarbon products wherein the feedstock is contacted at elevated temperature under endothermic high severity reaction conditions with a fluidized bed of acidic zeolite fine catalyst particles, comprising methods and means for:maintaining the fluidized catalyst bed in a vertical reactor having a turbulent reaction zone by passing vapor upwardly through the reaction zone at a velocity greater than dense bed transition velocity to a turbulent regime and less than transport velocity for the average catalyst particle;feeding a continuous stream of feedstock into the reaction zone, said feedstream comprising sufficient C.sub.3.sup.+ alkanes to require net endothermic reaction conditions;withdrawing a portion of coked catalyst from the reaction zone, oxidatively regenerating the withdrawn catalyst, heating the catalyst substantially above process temperature in the fluidized bed reactor, and returning hot regenerated catalyst to the reaction zone at a rate to control catalyst activity and reaction temperature under conditions of reaction severity to effect feedstock conversion to an aromatics-rich hydrocarbon effluent stream; andseparating an aromatics-rich product from the fluidized bed effluent stream.Aromatics yield is increased by recovering a recycle stream comprising C.sub.5.sup.+ aliphatic hydrocarbons from the fluidized bed effluent stream for further conversion in the fluidized bed to increase aromatics product yield.

摘要： A lubricant dewaxing process which is useful with difficult feeds, especially highly waxy feeds having paraffin contents in excess of 25 weight percent of feeds with high nitrogen levels, employs two-step dewaxing in which the first stage is carried out under relatively mild conditions to obtain extended catalyst cycle life between successive reactivations with a constant temperature for the duration of each dewaxing cycle. The second stage dewaxing is carried out under conditions which maintain the target pour point for the product with a progressively increasing temperature during each dewaxing cycle. More than one preliminary dewaxing stage may be provided in order to reduce severity in each stage with mild conditions and constant temperature being maintained in the preliminary steps. Using this process, extended catalyst cycle lives may be obtained with difficult feeds.

摘要： A fixed bed catalytic reactor having a porous bed of catalyst particles contained in a closed reactor shell, comprising inlet means for introducing a downwardly flowing mixed stream of gas and liquid reactants; phase separator means for receiving said mixed stream and directing liquid onto the porous catalyst bed, said separator means being disposed within the reactor shell between said inlet means and said porous catalytic bed; said separator means comprising an upper foraminous wall having a series of gas outlets permitting a substantially-gaseous phase to escape outwardly from the separator means into an upper reactor portion, and lower liquid distribution means for receiving a stream of substantially liquid phase and dividing said liquid phase into a plurality of spaced-apart liquid streams directed toward the porous catalyst bed; and means for recovering gaseous and liquid reaction products from the reactor shell. The phase separator-distributor is particularly useful for retrofitting a reactor to accommodate mixed flow without requiring welding internal structures onto the reactor shell. In a petrochemical complex, such separation and distribution system is advantageous in converting a reactor system for hydrotreating of a hydrocarbon distillate, such as dewaxing.

摘要： A process for upgrading oil feedstock wherein the feedstock is hydrocracked, flashed and/or distilled. The bottoms are then vacuum distilled to adjust viscosity and volatility. The refined feed is then dewaxed under high pressure by a medium pore molecular sieve. The dewaxed material is then cascaded to a hydrofinishing step, where it is contacted with an aromatics saturation catalyst having a metal hydrogenation function in order to produce, after appropriate flashing and distillation, lubricant products having high Viscosity Index, low aromatics content, low volatility and excellent stability to light in the presence of oxygen.
