Within the last 3 decades, fossil fuels have been the largest source of greenhouse gas emissions. Energy intensive industries are the main energy-consuming sectors in Iran. Non-metallic mineral products, basic metals, and chemical products are considered to be the most energy intensive industries in Iran. this paper means to evaluate the environmental efficiency of industrial sector during 2008...

The study investigates the effect of aluminium oxide nanoparticles as an additive to Madhuca Indica (mahua) methyl ester blends on performance, emission analysis of a single-cylinder direct injection diesel engine operated at a constant speed at different operating conditions. The test fuels are indicated as B10A0.2, B10A0.4, B20A0.2, B20A0.4 and diesel respectively. The results indica...

Demineralization of coals and coal-derived chars is part of an effort to developalternative fuels from coal. Pyrolysis and some gasification processes yieldchars containing a large fraction of the calorific value of the feed coal andessentially all of its mineral matter. In the work reported here, three gasifi-cation chars produced from anthracite, bituminous, and subbitumin...

The modern industrial cycle is mainly based on non-renewable mineral resources extracted from the Earth’s crust. After being processed and transformed into commodities, the products of mining become manufactured products which go through the economic system and are then discarded in the form of gaseous, liquid or solid waste. Eventually, the mass of the output in the form of waste must balance ...

BACKGROUND The association between solvents and Alzheimer's disease (AD) has been the subject of several studies. Yet, only few studies have examined the various solvents separately, and the controls have rarely been monitored long enough. For these reasons and others, we believe that further studies are required. OBJECTIVES The objective of this study was to identify solvents associated with...

The current study involves an experimental investigation of the decomposition of various biomass feedstocks and their conversion to gaseous fuels such as hydrogen. The steam gasification process resulted in higher levels of H2 and CO for various CO2 input ratios. With increasing rates of CO2 introduced into the feed stream, enhanced char conversion and increased CO levels were observed. While C...
