What are the steps in the methane reforming process?
The Steam Methane Reforming process can be broken down into five distinct steps: 1. Water enters the furnace, producing steam at a very high temperature. 2. Steam reacts with natural gas, producing hydrogen and carbon monoxide. 3. In the water shift reactor, carbon monoxide and steam react to form carbon dioxide and more hydrogen gas.
What is the equilibrium conversion graph for methane?
21 equilibrium conversion graph of steam reforming of methane against temperature, pressure and steam/carbon ratio.[11] It can be observed from the graph that in order to maintain a high methane conversion, it is necessary to operate the system at high temperature, low pressure, and relatively high steam to carbon ratio.
What is the ratio of steam to carbon in steam reforming?
In addition to computing the micro-kinetic model, experimental work for methane steam reforming was conducted. A steam to carbon ratio of 2:1 was fed to the packed bed reactor, where experimental conversion data were obtained.
How is hydrogen produced in the steam reforming process?
Steam Methane Reforming Process First, water must be heated in a furnace to produce steam. The superheated steam is mixed with natural gas in the reforming reaction, producing hydrogen gas and carbon monoxide. Carbon monoxide from the reforming reaction interacts with water again to produce more hydrogen and carbon dioxide.
