Syngas Production via Bi‐Reforming of Methane Using a Hydroxyapatite Supported Nickel Catalyst
Thanh Son Phan, Doan Pham MinhABSTRACT
A Ni/hydroxyapatite (HAP) catalyst was prepared, characterized, and investigated in the production of synthesis gas (syngas) from biogas through the bi‐reforming of methane (BRM). Under mild operating conditions (700°C reaction temperature and 1.4 bar total pressure, inlet molar composition of CH 4 /CO 2 /H 2 O/N 2 = 28.6/31.4/25.7/14.3, GHSV = 27 794 , 50 h‐on‐stream), this catalytic material has demonstrated promising results with 78% methane conversion. Increasing the steam‐to‐carbon (S/C, or steam‐to‐methane) molar ratio enhanced methane conversion while maintaining catalyst stability by decreasing solid carbon formation, as evidenced by characterization of the used catalyst.
