Methane steam reforming catalyst
WebSteam methane reforming (SMR) accounts for 76% of the dedicated hydrogen worldwide, and will remain the process of choice for large-scale hydrogen production for a long time. Durable and efficient catalysts are always desirable for this high-temperature-preferred process. Here, we report the design of a part Web31 okt. 2024 · Steam reforming is the most mature and economical technology used in the production of hydrogen and uses hydrocarbons reaction with steam to generate a H2 rich stream. It has been successfully deployed in industry using natural gas or naphtha as the feedstocks for many years.
