A steam methane reforming process, wherein the feed stream (10) in the reactor (30; 30 ') for processing, the reactor comprises a catalyst capable of promoting the hydrogenation and partial oxidation reaction of the feed stream (10). may be a refinery off-gas reactor. (30; 30 ') or ...
Steam reforming is a principal industrial process to manufacture synthesis gas (Syngas)for the production ofhydrogen,ammoniaandmethanol. The heart of the process is the tubular primary reformer where hydrocarbon feed (e.g. methane) reacts catalytically with steam to a mixture of hydrogen, carbon ox...
The steam methane reforming reactor includes a substantially cylindrical housing or shell and a tube disposed concentrically within the substantially cylindrical shell. The tube inc
A significant problem with steam reforming is carbon formation (coking). Carbon can be deposited on the reactor walls, creating heat transfer problems, or on the catalyst, resulting in its deactivation. Carbon can be formed as a result of the following reactions: Methane cracking (7.27)CH4⇆C...
The process may appear simple from an overall consideration, as the product composition is determined by simple thermodynamics, but in reality it is a complex coupling of catalysis, heat transfer and mechanical design. In commercial applications of methane reforming the activity of the catalyst is us...

The effects of temperature and pressure on the steam reforming of methane (CH 4+H 2O3H 2+CO) were investigated in a membrane reactor (MR) with a hydrogen permeable membrane. The studies used a novel silica-based membrane prepared by using the chemical vapor deposition (CVD) technique with...
The steam reforming reaction of methane to synthesis gas (CO and H2) was investigated in a very broad steam-to-carbon (S/C) ratio range (0.2–7.1) over a Ni/NiAl2O4 catalyst at 843, 858, and 873K. The dataset includes 179 data points at each temperature giving a detailed insight in...
Methane fuel was first investigated in order to find out some aspects not covered in the literature about the USR process: i.e. the mechanism by which the steam reforming and the NiO reduction reactions occurred, whether carbon formation took place and how sensitive the process was to it. Det...
