Low temperature selective catalytic reduction (SCR) catalysts were prepared by using acetic acid modified fly ash (ACFA) and TiO2 with the loading of Mn-Ce. The powder catalysts were characterized by BET, XRD and SEM. The effects of Mn-Ce molar ratio on the NO conversion of SCR catalyst were...

The transportation sector is one of the largest sources of greenhouse gases (GHGs) emissions in the United States. This study identifies scenarios for dramatically reducing future GHG emissions from the US transportation sector, specifically from light-duty vehicles (LDVs), by phasing in ammonia...

The recognition of forage production methods that maximize energy efficiency and minimize Greenhouse Gases (GHGs) emissions is essential. The aims of this survey were to assess the energy consumption, emissions of GHGs and global warming potential (GWP) of alfalfa production systems in Sistan...

In order to have sustainable development, it is necessary to manage energy use and greenhouse gases (GHG) emission in all production processes. The aim of this study was to compare wheat production in dryland and irrigated agroecosystems in terms of greenhouse gases (GHG) emission based on...

Energy efficiency improvements owing to technological progress in the energy-using appliances and equipment lower effective price of energy services and, in turn, result into behavioural ex-post increase in the consumption of energy. Thus, on net basis technological progress negatively...

The gas industry relies on indirect heating to prevent gas from freezing when it is transferred from high-pressure networks to lower pressure distribution systems. The main challenge in preheating natural gas is designing an indirect heating system capable of consistently maintaining a target...

The sultanate of Oman is a high-income country with economy dominated by hydrocarbon production accounting for 47.2% of GDP in 2014. Of the total, crude oil production contributed 43.8% to GDP while natural gas output accounted for contributed 3.4% of economic output. The sustained economic...

Municipal solid waste (MSW) management contributes substantially to climate change. The greenhouse gases (GHG) emissions from waste collection and landfill activities have a significant contribution. The carbon footprint is an important environmental indicator to express GHG emissions. Nowadays...

The damaging effect of climate change has made mankind to continuously pursue means of reversing global warming caused by greenhouse gases. CO2 gas according to available data for the year 2010 represents a whopping 76% of the emitted global greenhouse gases hence, making it a focal point in the...

In this study, the environmental behavior was characterized for a 840 Wp building-integrated photovoltaic (BIPV) system installed in the Department of Physics of the Faculty of Sciences at the National University of Colombia, Bogota campus. The methodology focused on the application of the...
