摘要:
The electrodesulfurization of heavy oil feedstreams is accomplished wherein a heavy oil feedstreams, along with hydrogen, is passed the cathode side of an electrochemical cell wherein the organically bound sulfur compounds in the heavy oil are reduced and the sulfur is released as hydrogen sulfide. The hydrogen sulfide can be fed directly into the anode side of the electrochemical cell to produce sulfur and hydrogen or it can be passed to an oxidation zone containing an aqueous solution of an oxidized metal salt.

This invention relates to a process for electrochemical conversion of dibenzothiophene type molecules of petroleum feedstreams selectively to mercaptan compounds that can then be more easily removed from the electrochemically treated product stream by either caustic extraction or thermal decomposition of the thiol functionality to hydrogen sulfide. The conversion of dibenzothiophenes to mercaptans is performed by electrochemical means in the substantial absence of hydrogen and in the substantial absence of water.

摘要:
The electrodesulfurization of heavy oils wherein a feedstream comprised of bitumen or heavy oil is conducted, along with an effective amount of hydrogen, to an electrochemical cell. A current is applied to the cell wherein sulfur from the feedstream combines with hydrogen to form hydrogen sulfide which is removed.
摘要:
This invention relates to the partial hydrogenation of sulfur containing petroleum feedstreams by electrochemical means. The partially hydrogenated feedstream is then conducted to processes for either conversion and removal of at least some of the sulfur-containing species from the electrochemical desulfurization process or adsorption and removal of at least some of the sulfur-containing species from the electrochemical desulfurization process.

This invention relates to the electrochemical conversion of dibenzothiophene type molecules of petroleum feedstreams to mercaptans that can then be removed, in one embodiment, by caustic extraction. In another embodiment, the mercaptans can be thermally decomposed, removing sulfur as hydrogen sulfide. The conversion of dibenzothiophenes to mercaptans is performed by electrochemical means without the required addition of hydrogen and in the substantial absence of water.

Provided is a hardware accelerator, central processing unit, and computing device. A hardware accelerator includes a task accelerating unit configured to, in response to a request for a new task issued by a hardware thread, accelerate the processing of the new task and produce a processing result for the task; a task time prediction unit configured to predict the total waiting time of the new task for returning to a specified address associated with the hardware thread. One aspect of this disclosure makes the hardware thread aware of the time to be waited for before getting a processing result, facilitating its task planning accordingly.
