Patent number: 10400182Abstract: The present disclosure relates generally processes and systems for converting a mixture of light hydrocarbons to liquid transportation fuels by first cracking the light hydrocarbons to an intermediate comprising olefins, which is converted by contacting with a catalyst comprising at least one zeolite in two separate conversion stages with an intervening recovery of liquid product. The first stage conversion favors oligomerization of larger olefins to form diesel range products that are collected prior to directing unconverted smaller olefins to be oligomerized in a second stage conversion conducted at a higher temperature and lower pressure.Type: GrantFiled: January 15, 2018Date of Patent: September 3, 2019Assignee: Phillips 66 CompanyInventors: Jianhua Yao, Hong Xie, Bruce B.

Patent number: 9371256Abstract: A heated petroleum-derived hydrocarbon is contacted with a triglyceride feed in a thermal cracking zone to decompose and remove impurities prior to hydrotreating the mixture to fuel range hydrocarbon. This process allows the use of a variety of low cost triglyceride feeds while reducing fouling of process equipment and catalyst. The process also reduces the use of chemicals required for conventional degumming of triglyceride feeds.Type: GrantFiled: March 31, 2014Date of Patent: June 21, 2016Assignee: PHILLIPS 66 COMPANYInventors: Jianhua Yao, Edward L. Sughrue, II, Dhananjay B. Ghonasgi, Xiaochun Xu

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: 8450542Abstract: An integrated process for the conversion of carbohydrate containing materials to gasoline boiling range hydrocarbons is disclosed. A carbohydrate containing material may be converted to a hydrogenated carbohydrate containing material with a bi-functional catalyst. The hydrogenated carbohydrate containing material may be reacted in the presence of another catalyst to form a reaction product containing non-aromatic and aromatic gasoline boiling range hydrocarbons.Type: GrantFiled: December 22, 2009Date of Patent: May 28, 2013Assignee: Phillips 66 CompanyInventors: Jianhua Yao, Edward L.

Publication number: 20120157742Abstract: The present disclosure relates to a process for the conversion of oxygen-containing hydrocarbons into long-chain hydrocarbons suitable for use as a fuel. These hydrocarbons may be derived from biomass, and may optionally be mixed with petroleum-derived hydrocarbons prior to conversion. The process utilizes a catalyst comprising Ni and Mo to convert a mixture comprising oxygenated hydrocarbons into product hydrocarbons containing from ten to thirty carbons. Hydro-conversion can be performed at a significantly lower temperature than is required for when utilizing a hydrotreating catalyst comprising Co and Mo (CoMo), while still effectively removing sulfur compounds (via hydrodesulfurization) to a level of 10 ppm (by weight) or less.Type: ApplicationFiled: December 20, 2011Publication date: June 21, 2012Applicant: CONOCOPHILLIPS COMPANYInventors: Yun Bao, Dhananjay B.

Publication number: 20120000820Abstract: This invention relates to a hydroprocessing process for the improvement of catalyst life. Such inventive process is carried out with intermittent or discontinuous addition of a co-feed stream when hydroprocessing petroleum based feedstock or an oxygen containing feedstock. More specifically, it has been found that intermittent or discontinuous addition of the co-feed stream such as carbon monoxide, carbon dioxide, or their precursors to the hydrogen stream can reduce the long term deactivation, extend the life and increase run length of a cobalt/molybdenum hydrotreating catalyst.Type: ApplicationFiled: April 29, 2011Publication date: January 5, 2012Applicant: CONOCOPHILLIPS COMPANYInventors: Jianhua YAO, Stephen L.
