摘要:
The invention relates to a hydroprocessed product that can be produced by hydroprocessing tar, such as a tar obtained from hydrocarbon pyrolysis. The invention also relates to methods for producing such a hydroprocessed product, and the use of such a product, e.g., as a fuel oil blending component.
摘要:
A method for upgrading a petroleum oil by a hydroprocessing reaction in which the oil is hydrogenated, includes the steps of: a. forming a liquid reaction mixture of the oil with water and an amphiphilic liquid in predetermined proportions to thereby render the oil and water miscible; b. introducing the liquid reaction mixture into an electrolytic reactor having one or more cathodic elements formed from a porous high surface area,conductive material; c. operating the reactor to form reactive hydrogen atoms whereby the oil is hydrogenated by the hydrogen atoms; d. removing the liquid mixture from the reactor; and e. separating the hydrogenated upgraded oil from the amphiphilic liquid and any remaining water, e.g., by distillation, recovering and recycling the amphiphilic liquid for use.
摘要:
The invention relates to processes for upgrading products obtained from hydrocarbon pyrolysis, equipment useful for such processes, and the use of upgraded pyrolysis products. A tar-containing stream recovered from the pyrolysis effluent is mixed with a utility fluid, preheated and subsequently hydroprocessed.
摘要:
In a process forthe hydroconversion of sulphur-containing heavy hydrocarbons in which the hydrocarbons and a gas containing carbon monoxide and steam are converted in a reactor at elevated temperature and pressure, improved results are obtaining using a gas comprising at least 3% by volume of hydrogen sulphide, based on water free gas.
摘要:
Supercritical upgrading reactors and reactor systems for upgrading a petroleum-based compositions comprising one or more catalyst layers and, in some embodiments, one or more purging fluid inlets, where one or more catalyst layers at least partially sift and convert heavy hydrocarbon fractions to light hydrocarbon fractions to produce an upgraded supercritical reactor product. In some embodiments, upgrading reactor systems comprise one or more supercritical upgrading reactors and one or more supercritical standby reactors alternating functions such that a supercritical upgrading reactor is converted to a supercritical standby reactor and the supercritical standby reactor is converted to a supercritical upgrading reactor, where the supercritical upgrading reactor upgrades a combined feed stream while a supercritical standby reactor delivers a cleaning fluid into the supercritical standby reactor.
摘要:
Heavy or refractory oils are hydroprocessed in the presence of added water and added hydrogen sulfide with or without a sturry catalyst comprising molybdenum sulfide. The water and hydrogen sulfide may originate from the catalyst preparation procedure.
