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...

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...

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...

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...

Keeping a sustainable environment is always a massive challenge for oil-exporting countries, and in that situation, industrialization and rapid growth of urbanization can add fuel to the fire. We investigate the effects of industrialization and urbanization on the CO2 emissions per capita in...

Due to the depletion of petroleum products and fatal emissions from the tailpipe of diesel engines it has become a need to seek for the alternative of petroleum products for long-term use. Currently, researchers and experts have come to the conclusion that biodiesel along with higher alcohols...

Railways transportation is still taken as an account of economic growth without considering the cost of environmental damages. Therefore, it is an urgent need at the national and global level to take into account the sustainability of environment by key sector. So this analysis has contributed...

As a potential means of offsetting diesel fuel usage and reducing the environmental impact of used tyres, this study investigates the NOx emissions of a modern commercial passenger vehicle run on a blend of diesel and tyre pyrolysis oil (TPO). The test vehicle was driven on a route...
