Reformer reaction
WebSteam reforming of ethanol aims at cracking ethanol in the presence of steam over a catalyst producing as much hydrogen and CO2 as possible. Depending on the catalyst used there are several reaction pathways that may occur in the steam reforming of ethanol. WebJul 19, 2012 · The reactions in the secondary reformer reactor are assumed to be carried inside two reactors in series. The first reactor, upper section, is the combustion zone, while the second reactor, bottom section, is the catalyst zone with nickel catalyst based on the alumina. In order to create a reactor design model for the secondary reformer in the ...

Websteps of steam reforming are surface reactions between adsorbed species. Six possible reaction mechanisms were considered in detail, and intrinsic rate equations were derived by using the Langmuir–Hinshelwood–Hougen–Watson (LH–HW) approach and Freundlich’s adsorption concept. Applying the method of parameter estimation and model ... WebThe most widespread process for rearranging hydrocarbon molecules is naphtha reforming. The initial process, thermal reforming, was developed in the late 1920s. Thermal reforming employed temperatures of 510–565 °C (950–1,050 °F) at moderate pressures—about 40 bars (4 MPa), or 600 psi—to obtain gasolines (petrols) with octane numbers of 70 to 80 …
