Patent number: 8440071Abstract: A hydrocracking system involves introducing a heavy oil feedstock and a colloidal or molecular catalyst, or a catalyst precursor capable of forming the colloidal or molecular catalyst, into a hydrocracking reactor. The colloidal or molecular catalyst is formed in situ within the heavy oil feedstock by 1) premixing the catalyst precursor with a hydrocarbon diluents to form a catalyst precursor mixture, 2) mixing the catalyst precursor mixture with the heavy oil feedstock, and 3) raising the temperature of the feedstock to above the decomposition temperature of the catalyst precursor to form the colloidal or molecular catalyst. The colloidal or molecular catalyst catalyzes upgrading reactions between the heavy oil feedstock and hydrogen and eliminates or reduces formation of coke precursors and sediment.Type: GrantFiled: May 23, 2011Date of Patent: May 14, 2013Assignee: Headwaters Technology Innovation, LLCInventors: Roger K.

Patent number: 8404103Abstract: Methods are disclosed for the hydrotreating and hydrocracking of highly aromatic distillate feeds such as light cycle oil (LCO) to produce ultra low sulfur gasoline and diesel fuel. Optimization of hydrotreater severity improves the octane quality of the gasoline or naphtha fraction. In particular, the operation of the hydrotreater at reduced severity to allow at least about 20 ppm by weight of organic nitrogen into the hydrocracker feed is shown to lead to these important benefits. Post-treating of the hydrocracker effluent over an additional hydrotreating catalyst bed may be desired to meet specifications for ultra low sulfur fuel components.Type: GrantFiled: November 1, 2011Date of Patent: March 26, 2013Assignee: UOP LLCInventors: Bart Dziabala, Vasant P.
