Patent number: 8932453Abstract: 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.Type: GrantFiled: June 1, 2011Date of Patent: January 13, 2015Assignee: Phillips 66 CompanyInventors: Jianhua Yao, Dhananjay B.

Patent number: 8231778Abstract: 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.Type: GrantFiled: December 31, 2008Date of Patent: July 31, 2012Assignee: UOP LLCInventor: Hemant B.
