Publikationer KTH

In this process light hydrocarbon feedstock and steam are converted in an endothermic reaction over a nickel Synthesis gas is one of the most important advancements that has ever occurred in energy production. Using this technology, for example, coal, biomass, waste products, or a combination of two or more of these can be gasified into a product that has roughly half the carbon footprint of coal alone. Syngas, also known as synthesis gas, synthetic gas or producer gas, can be produced from a variety of different materials that contain carbon. These can include biomass (wood gas), plastics, coal, municipal waste or similar materials. The synthesis gas generation process is a non‐catalytic process for producing synthesis gas (principally hydrogen and carbon monoxide) for the ultimate production of high‐purity hydrogen from Raw synthesis gas produced by the gasification of coal, heavy oil or similar carbonaceous material is contacted with a reforming catalyst at a temperature in the range between about 1000° and about 1800° F. and at a pressure between about 100 and about 2000 psig prior to adjustment of the carbon monoxide-to-hydrogen ratio and treatment of the gas to increase its B.t.u.
