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 H 2  and CO 2  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 H 2  and CO 2  (f) ranging from 0–0.99. The results indicate that SRP with 99% H 2  removal produces high H 2  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% CO 2  removal at same conditions of WPR (12), pressure (1 atm), and complete conversion of propane. Thus, SRP with H 2  removal is more energy saving process. In OSRP, lower OPR, higher WPR minimize CO and CH 4  production but at the expense of H 2  production. However, OSPR process is the most suitable process to provide most favourable H 2 /CO ratio in syngas. Molar H 2 /CO ratio in syngas in the range of 1–3 are found at  T ≥1,000 K, WPR≤6 in SRP, SRP with H 2  removal ( f =0.4–0.99) and OSRP (OPR=0.2–2). Thermal efficiency is higher than 80% in both SRP with H 2  or CO 2  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.
