The feed materials like natural gas, liquid gas or naphtha normally can be converted with water steam into synthesis gas in catalytic tube reactors under suitable temperature and pressure by using special designed catalyst. And the steam reforming of natural gas is the most common method, which is also known as steam methane reforming (SMR) also is the most economical method to produce commercial bulk hydrogen used in the industrial synthesis of ammonia and other chemicals widely. The reaction is at very high temperatures (700 – 1100 °C) with the presence of a metal-based catalyst (nickel), steam reacts with methane to yield carbon monoxide and hydrogen. This SMR process is quite different from with catalytic reforming of naphtha, an oil refinery process that also produces significant amounts of hydrogen along with high octane gasoline. SMR is approximately 65–75% efficient. The reaction is as below:

CH4 + H2O ⇌ CO + 3 H2

Additional hydrogen can be recovered by shift reaction in the presence of a copper or iron catalyst. The reaction is summarized as below:

CO + H2O ⇌ CO2 + H2

China is the biggest hydrogen producer, the capacity is around twenty million tons of hydrogen mostly with steam reforming of natural gas and light hydrocarbon. The worldwide ammonia production which is using hydrogen derived from steam reforming was 109 million metric tonnes in 2004.

SINOCATA offers normal steam reforming catalyst and also offer the alkali promoted steam reforming catalyst which is widely used in more than 200 industrial users in China. All this catalyst can be used to replace the US/European catalyst with lower cost and high performance which can save much on your catalyst investments.
