Abstract

The dry reforming of methane (DRM) can reduce CO2 and CH4 simultaneously. This study utilized East Natuna gas fields, composed of 70 % CO2 and 30 % CH4, for syngas production via DRM using a Ni–Ce@SiO2 catalyst. The kinetic parameters employed the Langmuir-Hinshelwood mechanism on the surface reaction as the rate-determining step. The simulation results provided an error margin below 5 %. A CO2:CH4 feed ratio of 70:30 at 700oC achieves higher CH4 conversion than a 50:50 ratio (97.10 % vs. 79.01 %), yet with lower H2/CO ratio (0.68 vs. 0.92). Also, higher temperatures impact shorter reactor lengths and swifter times to reach stable conversion.
