Carbon Dioxide Reforming Of Methane By Catalytic–Plasma Reactor Over Cu/Zn/γ–Al2O3

Abstract

Dalam kajian semasa, pengaruh kuasa input untuk penukaran CH₄ dan CO₂ ke syngas disiasat di dalam kedua–dua reaktor silinder plasma DBD dan reaktor plasma pemangkin. Diperhatikan bahawa untuk kedua-dua reaktor, input kuasa yang lebih tinggi menyokong tindak balas pemecahan dan bukannya penggabungan semula perantaraan ringan kepada hidrokarbon yang lebih berat, meningkatkan hasil H₂. Sementara itu, kehadiran mangkin Cu/Zn/Al₂O₃ mempertingkatkan pengeluaran H₂ daripada 16.5% kepada 19.1%, manakala nisbah H₂/CO kekal hampir malar berhampiran nilai 1, nisbah yang sesuai untuk proses FTS. Kata kunci: Plasma; catalytic, hydrogen; dry reforming of methane In the current study, the influence of input power for conversion of CH₄ and CO₂ into syngas was investigated in both DBD plasma and catalytic–plasma cylindrical reactors. It was observed that for both reactors, higher input power favored fragmentation reactions rather than recombination of light intermediates into heavier hydrocarbons, improving H₂ yield. Meanwhile, the presence of Cu/Zn/Al₂O₃ catalyst enhanced the H₂ yield from 16.5 % to 19.1%, while the H₂/CO ratio remained almost constant near unity, the suitable ratio for FTS processes. Key words: Plasma, catalytic, hydrogen, dry reforming of methane
