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.
用Ni - Ce@SiO2催化剂干重整甲烷同时利用CO2和CH4:参数化和模拟研究
甲烷干重整(DRM)可以同时还原CO2和CH4。本研究利用东纳土纳天然气田70% CO2和30% CH4组成,采用Ni - Ce@SiO2催化剂进行DRM合成气生产。动力学参数采用表面反应的Langmuir-Hinshelwood机理作为决定反应速率的步骤。仿真结果提供了小于5%的误差范围。在700℃条件下,当CO2:CH4进料比为70:30时,CH4转化率高于50:50(97.10%比79.01%),但H2/CO比较低(0.68比0.92)。此外,较高的温度会缩短反应堆长度,加快实现稳定转化的时间。
