“…The conversion of ethane in these studies was higher relative to the thermodynamic equilibrium values of ethane conversion alone due to a significant contribution of secondary reactions [44]. Relatively low selectivity to ethylene showed a significant contribution to the direct ethane dehydrogenation resulting in high hydrogen production [38,43].…”

“…Only a few Mo-based materials were reported for the ODH-CO 2 of ethane [38][39][40], but molybdenum carbide is well known as an alternative catalyst to noble metals in the highly selective reduction of CO 2 to CO [41,42]. Very high conversions of ethane in co-processing with CO 2 to produce hydrogen, ethylene, and CO were reported on the catalysts made up of the oxides of cobalt and molybdenum [38,43]. 58% conversion of ethane, 10.3% of CO 2 , and 21.9% ethylene yield were achieved over these systems at 700 °C [43].…”

“…The hydrogen production process can be carried out physically through experiments or chemically. Chemically natural gas processes such as methane, propane or ethane are reacted by steam (water vapor) at high temperatures (70°-1000°C) with the help of catalysts to produce hydrogen, oxidized carbon (CO 2 ), and carbon monoxide (CO) [9].…”

This research was conducted by utilizing seawater around mangrove forests, namely multi-functional areas in education. One of the objects of research by electrolysis seawater to determine the content of hydrogen gas is one of the renewable energy that has many advantages compared to other renewable energy. One simple method to produce hydrogen gas is by electrolysis of seawater whose source is unlimited. The electrolysis method in this study uses direct electric current or DC (Power Supply) and seawater with an electrolyte volume of 1000 ml, electrolysis time of 2, 4, 6, 8 minute using Copper electrodes (anode) and Aluminum (cathode) selection of cylindrical reactor types volume 1500 ml, operating conditions 36°C and 1 atm. As for the free variables, namely voltages of 5, 10, 15, 20, and 25 volt. With time variations, the results of the study showed that voltage greatly affects the decomposition of seawater into hydrogen gas. The highest hydrogen gas flow rate results can be at a voltage of 20 volts with 8 minutes of 1.8172 cc/sec (6545.51 ml/hour). The electrolysis time study on the decomposition of seawater into hydrogen gas had no significant effect. The electrolysis time of 6 and 8 minutes at a voltage of 20 and 15 volt showed high hydrogen gas results.

“…Moreover, bio-alcohols that are made up of methanol and ethanol produce ethylene and dimethyl ether (DME) [2]. A new approach for ethylene production is the simultaneous production of ethylene and hydrogen through carbon dioxide-assisted conversion of ethane [2,3]. Production of olefins from a biomass feedstock is of high interest nowadays, with hydro-deoxygenation or catalytic cracking of the bio-oil for its upgrading to olefins and gasolinetype fuel being the most effective route [4].…”

Oxidative dehydrogenation of light alkanes is an attractive route for the production of olefins. This method does not need much energy, while common processes such as propane dehydrogenation and cracking require external energy resources and cause rapid catalyst deactivation. In this research, an isothermal one-dimensional model of a fixed-bed reactor was considered for oxidative dehydrogenation of propane over a V 2 O 5 /graphene catalyst. Operational parameter sensitivity analysis showed that high temperature (450-500 °C), high pressure (7-8 atm), a moderate molar propane to air feed ratio (about 0.7), and a low feed flow rate enhanced the propane conversion and propylene productivity. However, for the production of propylene as desirable product, low temperature, low pressure, a high molar ratio, and a high feed flow rate are preferred. Thus, to determine the exact interval of operational parameter values, a multi-objective optimization was performed for the yields of propylene and CO x , revealing a maximum propylene yield of ~40 %. For safety reasons, a feed molar ratio of propane to air of > 0.6 was preferred, which is not in the flammable region.
