摘要:
Systems and processes for producing hydrogen gas (H 2 ) from water (H 2 O) are described. A process can include contacting H 2 O with a catalyst that includes iron sulfide at a reaction temperature of 500 °C to 800 °C to produce a product stream that includes H 2 and optionally hydrogen sulfide gas (H 2 S).
摘要:
The invention relates to a method for removing a sulphur deposit from a well and recovering an elemental sulphur stream, in which a liquid solvent dissolves all or part of the sulphur deposit by physical interaction, and said dissolved sulphur is converted into H 2 S by chemical extraction with H 2 , as well as a device for carrying out said method.
摘要:
The present invention relates to a method for the catalytic conversion in vapor phase of disulfide oil into methane and hydrogen sulfide, comprising the step of contacting disulfide oil, eventually in the presence of water, with a supported transition metal catalyst.
摘要:
The present invention relates to a reactor and to a process for synthesis of hydrogen sulphide from elemental sulphur and hydrogen at elevated pressure and elevated temperature. The invention further relates to the use of the reactor for preparation of hydrogen sulphide in high yield and with a low H 2 S x content.

摘要:
Plants and methods are presented in which organosulfur compounds in a mixed alcohol synthesis reactor effluent are converted into hydrogen sulfide (H2S). The volatility and relative insolubility of H2S reduces the overall sulfur content of the mixed alcohol synthesis product stream while significantly reducing or even eliminating the need for process steps/equipment to remove organosulfur compounds from liquid and gaseous products.

The detecting and monitoring of solid structure or phase transformation, such as those used for testing the formation of gas hydrates and their inhibition by chemical additives may be conducted in a multi-test assembly of laboratory bench scale loops. The test loop contains a fluid that includes water and hydrate-forming guest molecules such as methane, ethane, carbon dioxide and the like at hydrate-forming conditions of low temperature and high pressure. A small bit or "pig" may be circulated through the test loop at variable speeds to circulate the fluid in the loop. The pig may be moved or impelled through the test loop remotely. The exterior of the pig and/or the interior of the loop may be smooth and/or have a friction-reducing coating thereon to facilitate movement of the pig through the loop. The formation of hydrates may be monitored with consistent and reproducible results.
摘要:
Apparatus and methods for recovering sulfur from acid gases. Acid gases containing relatively high amounts of carbonyl sulfide and/or one or more types of mercaptans can be treated in a sulfur recovery system employing an acid gas enrichment zone and a tail gas treatment zone, where partially-loaded sulfur absorbing solvent from the tail gas treatment zone is employed for sulfur absorption in the acid gas enrichment zone. Off-gas from the acid gas enrichment zone can be combined and hydrogenated with a sulfur recovery unit tail gas thereby increasing the total amount of sulfur recovery from the initial acid gas.
