Chemical looping gasification (CLG) is an effective coal utilization technology. In this work, the CLG of bituminite was investigated through fixed-bed batch experiments using NiFe2O4 oxygen carrier (OC) to achieve high-quality syngas. The changes in phase during chemical reaction and mechanism were explored. results show that elevated temperature adding a fraction steam facilitate reaction. Ad...
Ash and coal produced from fire influence the soil and few studies about these effects are available. For this purpose, this study was performed to investigate the effect of ash and coal on hydrological, physical and chemical properties of soil in Charat rangeland that has a history of fire. Systematic-random sampling was implemented in two plant types Astragalus gossypinus and Artemisia aucher...
Organic aerosol (OA) constitutes a substantial fraction of fine particles and affects both human health and climate. It is becoming clear that OA absorbs light substantially (hence termed Brown Carbon, BrC), adding uncertainties to global aerosol radiative forcing estimations. The few current radiative-transfer and chemical-transport models that include BrC primarily consider sources from bioge...
Large reserves of coal in Tabas region of Iran are characterized by low ash and high caking index, suitable for use in metallurgy as coking coal. However, these coals cannot be gainfully utilized because of their high sulfur content. In this work, studies on desulfurization of Tabas coals were carried out in a batch reactor using various reagents. The most effective reagents,<...
