Methane Reforming: Solving the Hydrogen Blues - Chemical …
Autothermal reforming. Conventional SMR utilizes a fired heater to produce the energy that enables the reaction to take place. This fired heater combusts natural gas and creates a low-concentration stream of CO 2 at atmospheric pressure. Although this can be captured, it requires large and expensive equipment and is harder to capture …
