Analysis Techno-Economic of Producing Syngas by Using Various Metallic Catalysts in Steam Reformer of PUSRI II Palembang

摘要

Nickel as economical catalyst has been used in various process application. One process udapplication that uses this catalyst is the steam reformer in PT PUSRI II Palembang, Indonesia as part of an overall process to produce syngas from natural gas. Through nickel catalyst, the conversion of steam reformer is definitely high, but large amount of fuel to increase the steam reformer temperature is needed and the catalyst easily deactivates with sulfur and high temperature. Techno-economical analysis assessments highlight the various technological possibilities and economic aspects involved in the production of syngas. This method has been done at the steam reformer part of PT PUSRI II Palembang, in this research aimed to investigate the comparison of catalysts performance of platinum, palladium, cobalt, and nickel to syngas conversion. Various catalysts Pt/Pd/Co/Ni are the variable of the research for the techno-economic analysis, which consisted of operating condition, catalyst volume and price, fuel economization and syngas conversion. Trough techno-economic analysis, platinum was found to give the best results in analysis compared with others, giving low process temperature, catalyst volume used, fuel economization and high syngas conversion of up to 61 % at 653 K.
