The catalytic activity, thermal stability and deactivation rate of the synthesized catalysts were evaluated at atmospheric pressure on a conventional fixed bed reactor at the temperature ranges of 873-1073 K for 4 h at constant methane flow-rate. The results suggested that the introduction of Pd on Ni/Al2O3 can significantly enhance the catalytic activity of the catalysts. A slower deactivation rate was observed for Ni-Pd/Al2O3 catalyst. This is due to the positive effect of Pd on metallic Ni particles, improving the ability of the catalyst to accumulate carbon, thus enhancing the thermal stability at elevated temperatures. © Copyright 2017, AIDIC Servizi S.r.l. date: 2017 publisher: Italian Association of Chemical Engineering - AIDIC official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85021668369&doi=10.3303%2fCET1757058&partnerID=40&md5=98f45810c77622b942262698ec89592b id_number: 10.3303/CET1757058 full_text_status: none publication: Chemical Engineering Transactions volume: 57 pagerange: 343-348 refereed: TRUE isbn: 9788895608488 issn: 22839216 citation: Lock, I.S.M. and Lock, S.S.M. and Vo, D.-V.N. and Abdullah, B.
