A reverse flow reactor is utilized to convert CH<sub>4</sub> to carbon dioxide (CO<sub>2</sub>) as a means of reducing the effect of global warming. The dynamics of its dependent variables can be stated by a set of convective-diffusion equations. In this article, we examined analytical solutions of temperature dynamics and methane conversion for a 1-D pseudo homogeneous model without refrigeration by using the homotopy analysis method. The results show that temperature and conversion of methane will go to constant when time goes to infinity.</p> <p><strong><em>ABSTRAK: </em></strong>Metana (CH<sub>4</sub>) merupakan salah satu gas rumah hijau paling berbahaya di atmosfera. Reaktor aliran balik telah dipakai bagi menukar CH<sub>4</sub> kepada CO<sub>2</sub> bagi mengurangkan kesan pemanasan global. Dinamik pemboleh ubah bersandar ini dapat diterangkan melalui satu set persamaan konvektif-difusi. Artikel ini akan mengkaji penyelesaian analisis dinamik suhu dan penukaran metana bagi model 1-D pseudo-homogen tanpa penyejukan dengan menggunakan kaedah analisis homotopi. Hasil kajian menunjukkan bahawa suhu dan penukaran metana akan berterusan dengan masa tak terhingga.</p>}, number={1}, journal={IIUM Engineering Journal}, author={Suharsono, Suharsono and Wulandari, Sri and Nuryaman, Aang and Usman, Mustofa and Wamiliana, Wamiliana and Daoud, Jamal}, year={2020}, month={Jan.}, pages={129–137} }
