The present study aims to explore the possibility of promoting hydrogen and syngas production capacity and quality by steam (SRP) and oxidative steam (OSRP) reforming of propane with and without H2 and CO2 removal. Conditions studied are temperature range of 600–1,100 K under atmospheric pressure with steam to propane feed ratio (WPR) of 1–18, oxygen to propane feed ratio (OPR) and fractional removal of H2 and CO2 (f) ranging from 0–0.99. The results indicate that SRP with 99% H2 removal produces high H2 yield of 9.93 moles close to theoretical value of 10 moles at relatively low temperature (750 K) than SRP (950 K). Approximately identical results are achieved at 950 K with 99% CO2 removal at same conditions of WPR (12), pressure (1 atm), and complete conversion of propane. Thus, SRP with H2 removal is more energy saving process. In OSRP, lower OPR, higher WPR minimize CO and CH4 production but at the expense of H2 production. However, OSPR process is the most suitable process to provide most favourable H2/CO ratio in syngas. Molar H2/CO ratio in syngas in the range of 1–3 are found at T≥1,000 K, WPR≤6 in SRP, SRP with H2 removal (f=0.4–0.99) and OSRP (OPR=0.2–2). Thermal efficiency is higher than 80% in both SRP with H2 or CO2 removal than SRP(69.39%). The thermal efficiency in OSRP is less than 69%. Hence, propane reforming process in hydrogen selective membrane reactor, provides high quality of hydrogen at relatively lower energy utilization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
