利用CO2或H2O对甲烷进行重整是生产合成气最重要的工艺之一,其合成气是合成高价值化学品的最重要中间体之一。目前工业上CH4干重整温度需高于800C,其催化剂为负载型Ni基催化剂,面临两个挑战。第一,Ni基催化剂易失活在高温还原气体环境中下易烧结。第二,在金属银纳米颗粒表面容易发生副反应即甲烷热解,从而生成积碳。

In both cases, it is important to gain insights into the interactions of the CO2-rich phase—liquid or gas—with the aqueous medium (H2O) in the pore space below the seafloor or in the ocean. Thus, the CH4-CO2 binary and CH4-CO2-H2O ternary mixtures were investigated at relevant ...

The direct reaction of methane with H2O (steam methane reforming (SMR)) leads to H2 and CO (and CO2), whereas carbon deposition—regardless of its type—is an unwanted reaction. The concept presented in this work assumes dividing that process into two reactors, which allows one to obtain ...
