  • Patent number: 9719034
    Abstract: Methods are provided for processing a gas oil boiling range feedstock, such as a vacuum gas oil, in a single reaction stage and/or without performing intermediate separations. The methods are suitable for forming lubricants and distillate fuels while reducing or minimizing the production of lower boiling products such as naphtha and light ends. The methods can provide desirable yields of distillate fuels and lubricant base oils without requiring separate catalyst beds or stages for dewaxing and hydrocracking. The methods are based in part on use of a dewaxing catalyst that is tolerant of sour processing environments while still providing desirable levels of activity for both feed conversion and feed isomerization.

  • Patent number: 9005430
    Abstract: The invention relates to the integration of a process for hydrotreatment of distillates (light and/or middle), that operates under a hydrogen partial pressure of 0.5 to 6.0 MPa, with a process for hydrotreatment/hydroconversion of middle and/or heavy distillates that operates at a hydrogen partial pressure that is at least 4.0 MPa higher than the hydrogen partial pressure of the process for hydrotreatment of distillates (light and/or middle). The integration resides in the use of the hydrogen-rich gas, obtained from the hydrotreatment/hydroconversion effluents, in the process for hydrotreatment of distillates (light and/or middle) and in the adjustment of the pressure level of this hydrogen-rich gas removed from the hydrotreatment/hydroconversion. This invention makes it possible to considerably reduce the net consumption of make-up hydrogen in the process for hydrotreatment of distillates (light and/or middle).

  • Patent number: 8932453
    Abstract: This invention relates to a hydroprocessing process with improved catalyst activity when hydroprocessing petroleum based feedstock or an oxygen containing feedstock. This invention also relates to a hydrotreating process with improved hydrodesulfurization (HDS) activity of a hydrotreating catalyst such as Co/Mo by co-feeding carbon monoxide or its precursors. Such inventive process confirms that adding a small amount of CO to H2 in a hydrotreater for a few days leads to an increase in product sulfur due to the inhibition of CO on the hydrotreating catalyst such as Co/Mo. However, it has been unexpectedly found that after the CO was removed from the hydrogen stream, product sulfur levels decreased to values below they were before CO addition which means the activity of the hydrotreating catalyst increased after the CO treatment.

  • Patent number: 8329610
    Abstract: The present invention relates to a hydrogenation catalyst composition, process for preparing the same and use thereof. The composition comprises a hydrogenation catalyst, an organonitrogen compound in an amount of 0.01%-20% by weight of the catalyst, a sulfiding agent in an amount of 30%-150% by weight of the sulfur-requiring amount calculated theoretically of the hydrogenation catalyst, and an organic solvent in an amount of 0.1%-50% by weight of the catalyst. The preparation process comprises introducing the required substances onto the hydrogenation catalyst in oxidation state. By introduction of the organonitrogen compound, sulfur and organic solvent, the hydrogenation catalyst composition of the present invention may further increase the sulfur-maintaining ratio of the catalyst during the activation, slow down the concentrative exothermic phenomenon, decrease the rate of temperature rise of the catalyst bed layer, and improve the activity of the catalyst.

  • Patent number: 8231778
    Abstract: Methods are disclosed for hydrocracking processes that convert a significant portion of a heavy hydrocarbon feedstock such as vacuum gas oil (VGO) to lower molecular weight, lower boiling hydrocarbons. In addition to molecular weight reduction, the processes also substantially reduce the pour point of a recovered higher boiling fraction or unconverted oil, all or a portion of which may be used as a lube base stock, optionally after one or more further treatment steps such as hydrofinishing. The ability to reduce the pour point, through hydroisomerization, of the higher boiling fraction greatly improves the quality of this fraction, or unconverted oil, for use in lube base stock preparation. Advantageously, separate, conventional hydroisomerization and/or dewaxing steps, often requiring a noble metal catalyst, may be avoided in particular embodiments disclosed herein.
