A process for the hydroprocessing of a gas oil (GO) hydrocarbon feed to provide high yield of a diesel fraction. The process comprises a liquid-full hydrotreating reaction zone followed by a liquid-full hydrocracking reaction zone. A refining zone may be integrated with the hydrocracking reaction zone. Ammonia and other gases formed during the hydrotreatment are removed in a separation step prior to hydrocracking.

Gas oil hydroprocess

Novel liquid-full process for improving cold flow properties and increasing yield of middle distillate fuel feedstock by hydrotreating and dewaxing the feedstock in liquid-full reactors.

Process for improving cold flow properties and increasing yield of middle distillate feedstock through liquid full hydrotreating and dewaxing

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.

Hydroprocessing light cycle oil in liquid-full reactors

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.
