摘要： A process where the need to circulate hydrogen through the catalyst is eliminated. This is accomplished by mixing and/or flashing the hydrogen and the oil to be treated in the presence of a solvent or diluent in which the hydrogen solubility is "high" relative to the oil feed. The type and amount of diluent added, as well as the reactor conditions, can be set so that all of the hydrogen required in the hydroprocessing reaction is available in solution. The oil/diluent/hydrogen solution can then be fed to a plug flow reactor packed with catalyst where the oil and hydrogen react. No additional hydrogen is required, therefore, hydrogen recirculation is avoided and trickle bed operation of the reactor is avoided. Therefore, the large trickle bed reaction can be replaced by much smaller tubular reactor.
摘要翻译：消除了通过催化剂循环氢气的过程。这是通过在相对于油进料的氢溶解度“高”的溶剂或稀释剂的存在下混合和/或闪蒸待处理的氢和油。添加的稀释剂的种类和数量以及反应器条件可以设定为使得加氢处理反应中所需的所有氢都可以在溶液中获得。然后将油/稀释剂/氢溶液加入到填充有催化剂的活塞流反应器中，其中油和氢反应。不需要额外的氢气，因此避免了氢再循环，避免了反应器的滴流操作。因此，大的滴流床反应可以被更小的管状反应器代替。

摘要： A method of refining a petroleum product to remove aromatics and to separate paraffinic oils and waxes is provided. The method involves the utilization of phase equilibria wherein crystallized or solidified waxes, normally present in the pretroleum product, are used to remove oils from a liquid solvent phase containing dissolved aromatics present in the unrefined petroleum product. The wax containing the oils (26) is separated from the aromatic-containing solvent and is further processed to separate the waxes and oils (28). For petroleum products containing little, if any, wax, additional wax may be added and recycled back for further use in removing oils from the petroleum product. The method has particular application in preparing lubricant oils having a high viscosity index, where the presence of aromatics and wax can be detrimental.

摘要： A control system for a continuous liquid phase hydroprocessing reactor having an upper zone of gases and a substantially larger lower zone of liquids surrounding a catalyst, comprising: (a) an indicator located on said reactor, (b) means for sensing the quantity of liquid in said reactor; (c) an indicator reading obtained from said sensing means; (d) means for converting said indicator reading to an indicator signal; (e) a computer to receive said indicator signal; (f) means for transmitting the indicator signal to said computer; (g) a software program to interpret said indicator signal and make adjustments based on said indicator signal; (h) means for converting said adjustments to an adjustment signal; (i) means for transmitting said adjustment signal; (j) a hydrogen control valve, located upstream from said reactor, which adjusts the amount of hydrogen going into a reactor feed; (k) means for interpreting the adjustment signal at said hydrogen control valve; and (l) means for adjusting said hydrogen control valve based on said interpreting means.
