Reactor and process for the continuous production of hydrogen based on steam oxidation of molten iron

The present invention provides a reactor and gasification process for the continuous controlled production of hydrogen (H2) and a by-product synthesis gas (mixture of CO+H2+CO2), such a process called a hydrogen priority poly-generation process (HPPP). The reactor uses a circulating molten iron process, which is capable of gasifying a variety of carbonaceous materials including low rank coals and biomass. The process employs an iron steam oxidation-reduction cycle in a multi-chamber reactor including a multi-vessel reactor system, where in one compartment or vessel hydrogen is produced by steam oxidation of molten iron; and in a second compartment or vessel the iron is regenerated by carbon reduction of molten iron oxide thereby producing a by-product synthesis gas (CO+H2+CO2), and excess heat which can be used to produce steam, and in a third step the iron is purified before being returned to the steam oxidation step in the process. An embodiment of this process uses low rank coals having high ash levels in a reactor, which is designed to continuously extract ash from the molten iron bath. A second embodiment uses low ash carbon materials such as highly beneficiated coals in a simpler process that produces pure streams of hydrogen and CO.

Downhole percussion tool

A pressure fluid actuated downhole percussion tool includes a reciprocating piston hammer with differential transverse pressure surfaces cooperable with a cylinder housing, a guide sleeve and a bit carried exhaust tube to form opposed pressure fluid chambers to which pressure fluid may be conducted to deliver repeated impact blows to a bit having circumferentially spaced bosses and replaceable cutting inserts. The bit is drivenly connected to the tool by plural drive pins supported in circumferentially spaced grooves in the bit shank and in a removable sub supported by the tool housing. Improved earth penetration performance is realized utilizing a claw bit with a pressure fluid actuated percussion tool providing rotation as well as selective deliverance of impact blows through the bit.

Chemical vapor deposition and powder formation using thermal spray

A method for chemical vapor deposition using a very fine atomization or vaporization of a reagent containing liquid or liquid-like fluid near its supercritical temperature, where the resulting atomized or vaporized solution is entered into a flame or a plasma torch, and a powder is formed or a coating is deposited onto a substrate. The combustion flame can be stable from 10 torr to multiple atmospheres, and provides the energetic environment in which the reagent contained within the fluid can be reacted to form the desired powder or coating material on a substrate. The plasma torch likewise produces the required energy environment, but, unlike the flame, no oxidizer is needed so materials stable in only very low oxygen partial pressures can be formed. Using either the plasma torch or the combustion plasma, coatings can be deposited and powders formed in the open atmosphere without the necessity of a reaction chamber, but a chamber may be used for various reasons including process separation from the environment and pressure regulation.
