Web11 apr. 2024 · High performance solar reactor is critical for getting high yield of solar-driven chemical conversion process. In this paper, the performance of a cavity type concentrated solar reactor for methane dry reforming reaction was investigated and optimized with coupled optics-computational fluid dynamics modeling method. Web7 apr. 2024 · The sol–gel template technique makes it possible to synthesize a stable and efficient nickel catalyst based on magnesium-modified cerium oxide Ce0.5Mg0.5O1.5 for the combined steam and CO2 reforming of methane. To stabilize dispersed forms of the active component in the matrix of the support, the catalysts were synthesized by changing the … The reforming reaction takes place at high temperatures, making it slow to start up and requiring costly high-temperature materials. Sulfur compounds in the fuel will poison certain catalysts, making it difficult to run this type of system from ordinary gasoline . Meer weergeven 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 … Meer weergeven The reaction is conducted in multitubular packed bed reactors, a subtype of the plug flow reactor category. These reactors consist of an array of long and narrow tubes which … Meer weergeven Partial oxidation (POX) occurs when a sub-stoichiometric fuel-air mixture is partially combusted in a reformer creating hydrogen-rich syngas. POX is typically much faster than steam reforming and requires a smaller reactor vessel. POX produces … Meer weergeven • Biogas • Boudouard reaction • Catalytic reforming • Chemical looping reforming and gasification • Cracking (chemistry) Meer weergeven Steam reforming reaction kinetics, in particular using nickel-alumina catalysts, have been studied in detail since the 1950s. Meer weergeven Autothermal reforming (ATR) uses oxygen and carbon dioxide or steam in a reaction with methane to form syngas. The reaction takes place in a single chamber where the methane is partially oxidized. The reaction is exothermic. When the ATR uses carbon dioxide, the … Meer weergeven The capital cost of steam reforming plants is considered prohibitive for small to medium size applications.
