“…Its high oxygen content provides better combustion. Low-combustion temperature causes a reduce in the heat transfer loss, moreover the compression losses decreased thanks to the high latent heat of vaporization, thus, both resulting in higher engine efficiency [20][21][22].…”

In this study, the availability of methanol instead of ethanol was investigated in terms of performance, emission and combustion characteristics. The experiments were conducted in a single cylinder, four-stroke SI engine for different engine speeds at full engine load. Test fuels were prepared by 10% ethanol and methanol addition into gasoline. According to the experimental results, while methanol addition increased bsfc values by 10.3% compared to ethanol addition, it caused a reduction to the bte values by 6.12%. The methanol addition fuel has shown similar combustion characteristics with ethanol addition fuel. Although the methanol addition decreased CO2, CO, HC and NOx emissions by 6.48%, 26.6%, 4.75% and 9.16% respectively compared to ethanol addition, it has higher oxygen emission values by 15.3% due to its higher oxygen content than ethanol. These results show that methanol can also use as an additive for gasoline like ethanol.

“…With the high demand for alternative energy resources due to climate change and global warming, fuel cells producing water (H 2 O) as the only byproduct have received a lot of focus to reduce the emission of noxious pollutions produced by the use of fossil fuel. , Actually, hydrogen (H 2 ) used in fuel cells to produce power is made from steam reforming (SR) of light hydrocarbons such as methane, ethane, and propane, − coal gasification, − water electrolysis, − etc. In particular, the SR of light hydrocarbons accounts for 95% of the total H 2 production in the United States and methane in natural gas is the principal source of SR. , …”

Integrative technoeconomic analysis (iTEA) with process simulation and economic analysis and integrative carbon footprint analysis (iCFA) of ethane steam reforming (ESR) for H2 production in a membrane reactor (MR) was carried out to identify its technical, economic, and environmental feasibility in Korea. From process simulation, process conditions were set to perform economic analysis through itemized cost estimation, sensitivity analysis, and probability analysis using a Monte-Carlo simulation method. The respective H2 production costs of 3.678 and 2.926$ kgH2 –1 were obtained in a conventional reactor and an MR and main economic items of reactant and labor were confirmed using sensitivity analysis. A H2 selling price of 4.091$ kgH2 –1, assuming an onsite H2 refueling station using proposed ESR, was obtained, which can be compared with the current and future H2 selling prices from H2 refueling stations, the United States Department of Energy, and the projected H2 selling prices based on Hydrogen Roadmap from the Korean government. In addition, cumulative probability curves and frequency graphs for H2 selling price by varying main economic items were created to show the uncertainty of the proposed ESR through probability analysis. Moreover, the reduction in the CO2 emission rate of about 13.3% was obtained in an MR through the CO2 flow diagram of iCFA.

Summary Over the years, research focused has been on the development of active and stable catalysts for hydrogen (H2) production by steam methane reforming (SMR). However, there is less attention on the individual and interaction effect of key process parameters that influence the catalytic performance of such catalysts and how to optimize them. The main objective of this study is to investigate the individual and interaction effects of key parameters such as methane partial pressure ( PCH4true) (10‐30 kPa), steam partial pressure ( PH2normalO()gtrue) (10‐30 kPa), and reaction temperature (T) (750‐850°C) on H2 yield and methane (CH4) conversion during SMR using Box‐Behnken experimental design (BBD) and response surface methodology. The H2 production was catalyzed using Ni/LSCF prepared by wet impregnation method. The evaluation of the Ni/LSCF using different instrument techniques revealed that the catalyst exhibited excellent physicochemical properties suitable for SMR. Response surface models showing the individual and interaction effect of each of the parameters on the H2 yield and CH4 conversion were obtained using the set of data obtained from the BBD matrix. The three parameters were found to have significant effects on the H2 yield and CH4 conversion. At the highest desirability of 0.8994, maximum H2 yield and CH4 conversion of 89.77% and 89.01%, respectively, were obtained at optimum conditions of 30 kPa, 28.86 kPa, and 850°C for PCH4, PH2normalO()g, and temperature, respectively. The predicted values of the responses from the response surface models were found to be in good agreement with the experimental values. At optimum conditions, the catalyst was found to be stable up to 390 minutes with time on stream. The characterization of the used catalyst using thermogravimetric analysis, scanning electron microscopy, energy‐dispersive X‐ray spectroscopy, and transmission electron microscopy showed some evidence deposition of a small amount of carbon on the catalyst surface.
