Patent number: 9365782Abstract: A process for the hydroprocessing of a low-value light cycle oil (LCO) hydrocarbon feed to provide a high-value diesel-range product. The process comprises a hydrotreatment stage followed by a hydrocracking stage, each of which is conducted under liquid-full reaction conditions wherein substantially all the hydrogen supplied to the hydrotreating and hydrocracking reactions is dissolved in the liquid-phase hydrocarbon feed. Ammonia and optionally other gases formed during hydrotreatment are removed in a separation step prior to hydrocracking. The LCO feed is advantageously converted to diesel in high yield with little loss of hydrocarbon to naphtha.Type: GrantFiled: August 3, 2015Date of Patent: June 14, 2016Assignee: E I DU PONT DE NEMOURS AND COMPANYInventors: Hasan Dindi, Alan Howard Pulley, Thanh Gia Ta, Vincent Adam Kuperavage, Jr.

Patent number: 9139782Abstract: A process for hydroprocessing hydrocarbons in a combined targeted pretreatment and selective ring-opening unit wherein the targeted pretreatment comprises at least two stages in a single liquid recycle loop. The process operates as a liquid-full process, wherein all of the hydrogen dissolves in the liquid phase. Heavy hydrocarbons and light cycle oils can be converted in the process to provide a liquid product having over 50% in the diesel boiling range, with properties to meet use in low sulfur diesel.Type: GrantFiled: February 11, 2011Date of Patent: September 22, 2015Assignee: E I DU PONT DE NEMOURS AND COMPANYInventors: Hasan Dindi, Luis Eduardo Murillo, Alan Howard Pulley

Patent number: 4234555Abstract: This invention is a simple and effective method for removing uranium from aqueous HF solutions containing trace quantities of the same. The method comprises contacting the solution with particulate calcium fluoride to form uranium-bearing particulates, permitting the particulates to settle, and separting the solution from the settled particulates. The CaF.sub.2 is selected to have a nitrogen surface area in a selected range and is employed in an amount providing a calcium fluoride/uranium weight ratio in a selected range. As applied to dilute HF solutions containing 120 ppm uranium, the method removes at least 92% of the uranium, without introducing contaminants to the product solution.Type: GrantFiled: June 29, 1978Date of Patent: November 18, 1980Assignee: The United States of America as represented by the United States Department of EnergyInventors: Howard Pulley, Steven F.
