Steam reforming or steam methane reforming (SMR) is a method for producing syngas (hydrogen and carbon monoxide) by reaction of hydrocarbons with water. Commonly natural gas is the feedstock. The main purpose of this technology is often hydrogen production , although syngas has multiple other uses such as production of ammonia or methanol .
These fragments were then used as building blocks in the structure generator. This structure generator was part of a CASE system, ESESOC. [23] Breadth-first search generation. Molecular structure generation is explained step by step. Starting from a set of atoms, bonds are added between atom pairs until reaching saturated structures.
A natural-gas processing plant in Aderklaa, Austria. Natural-gas processing is a range of industrial processes designed to purify raw natural gas by removing contaminants such as solids, water, carbon dioxide (CO 2), hydrogen sulfide (H 2 S), mercury and higher molecular mass hydrocarbons to produce pipeline quality dry natural gas [1] for pipeline distribution and final use. [2]
These systems can be a gas storage bottle or a gas generator. Hydrogen can be generated by electrolysis of water, the action of steam on red hot carbon-based fuel, by gasification of hydrocarbon fuel, or by the reaction of acid on metal. Hydrogen can also cause the embrittlement of metals. Hydrogen is a flammable gas, which is a safety concern ...
Rarely used generator sets may correspondingly be installed as natural gas or LPG to minimize the fuel system maintenance requirements. Spark-ignition internal combustion engines operating on gasoline (petrol), propane, or LPG are commonly used as portable temporary power sources for construction work, emergency power, or recreational uses.
Flame from a wood gas generator. Wood gas is a fuel gas that can be used for furnaces, stoves, and vehicles. During the production process, biomass or related carbon-containing materials are gasified within the oxygen-limited environment of a wood gas generator to produce a combustible mixture.
Scheme of a solid-oxide fuel cell. A solid oxide fuel cell (or SOFC) is an electrochemical conversion device that produces electricity directly from oxidizing a fuel. Fuel cells are characterized by their electrolyte material; the SOFC has a solid oxide or ceramic electrolyte.
However, at the moment most hydrogen gas is produced by steam reforming light hydrocarbons, a process which produces a mixture of gases that also contains CO (1–3%), CO 2 (19–25%), and N 2 (25%). [41] Even tens of parts per million of CO can poison a pure platinum catalyst, so increasing platinum's resistance to CO is an active area of ...
