Steam methane reforming (SMR) process is regarded as a viable option to satisfy the growing demand for hydrogen, mainly because of its capability mass production hydrogen and maturity technology. In this study, an economically optimal configuration SMR proposed by investigating six scenarios with different design operating conditions, including CO2 emission permits capture sale. Of scenarios, i...
A number of studies have shown that elevated atmospheric CO2 ([CO2]) affects rice yields and grain quality. However, the responses of root-associated bacteria to [CO2] elevation have not been characterized in a large-scale field study. We conducted a free-air CO2 enrichment (FACE) experiment (ambient + 200 μmol.mol(-1)) using three rice cultivars (Akita 63, Takanari, and Koshihikari) and two ex...
Structure, morphology and composition of two Pd/Ga2O3 methanol steam reforming catalysts were correlated with the associated activity and selectivity changes in the methanol steam reforming reaction and linked to studies on pure Ga2O3 supports. For both systems, that are, a Pd/Ga2O3 thin film model catalyst and a powder-supported Pd catalyst, we identified a temperature range in which the reduc...
One of the matured methods for producing hydrogen in bulk is steam methane reforming (SMR). The two commercial aspects from SMR are with shift reactor (SR) and dry (DRM). Although SR produces high yield, it emits a large quantity carbon dioxide (CO2). On contrary, DRM produce low yield but favorably emit CO2. However, not obvious which these more favourable economically. Consequently, using UNI...
A 1-D heterogeneous model of sorption-enhanced steam methane reforming (SE-SMR) process in a packed bed reactor consisting nickel catalyst well mixed with CO2 sorbent particles is investigated for three types common sorbents. The performance SE-SMR studied under low medium pressure conditions (3 – 11 bar) to find the optimum operating conditions. Optimal CaO sorption corresponding 82% CH4 conve...
Abnormal growth of population and development enormously increases energy demand. In present scenario utilization of fossils fuels to meet this demand is not enough and also leads to pollution, global warming, climate change as well as natural disaster. Therefore, hydrogen as energy carrier is a major option on these prospects as it is non-polluting and renewable. The renewable hydrogen energy ...
