background:: this study developed a smart co 2 detector, which attach to the general ventilation system to reduce the gas level. methods: indoor air quality measurement was performed in five selected rooms between january 2015 to february 2015 using tsi q-trak tm indoor air monitor 7575. the perceived indoor air quality conditions was gathered using questionnaires adopted from the industrial co...

A series of x(Co, Mn)/TiO2 catalysts (x=2–12wt.%) containing 25%Co and 75%Mn were prepared by the co-impregnation method. All prepared catalysts have been tested in Fischer-Tropsch synthesis for production of C2-C4 olefins. It was found that the catalyst containing 8wt.%(Co,Mn)/TiO2 is an optimal catalyst for production of C...

Methanation of both CO and CO2 with electrolysis-sourced hydrogen is a key step in power-to-gas technologies nickel as the most prominent catalyst. Here, detailed, thermodynamically consistent reaction mechanism for methanation reactions over Ni-based catalysts presented. This microkinetic model based on mean-field approximation comprises 42 among 19 species. The was developed experiments from ...
