Solid biofuel is considered as a possible substitute for coal in household heat production because of the available and sustainable raw materials, while NOx emissions from its combustion have become serious problem. Nitrogen-containing compounds pyrolysis products important effects on conversion fuel-N into NOx-N. Understanding these converting pathways environmentally friendly use biomass fuel...
Silicon extraction from rice straw (RS) has gained attention due to its increasing demand for various applications. This study investigated the potential producing bio-silica RS digestates, and leached with agro-industrial waste, such as corn-steep liquor (CSTL) cassava-steep wastewater (CSWW). The results indicated that pretreated (PT) digested methanogenic ash (RSA) samples contain amorphous ...
Selective leaching of Li from spent LIBs thermally pretreated by pyrolysis and incineration between 400 700 °C for 30, 60, 90 min followed water at high temperature L/S ratio was examined. During the thermal pretreatment Li2CO3 LiF were leached. Along with salts, AlF3 also found to be leached an efficiency not higher than 3.5%. The time did have a significant effect on efficiency. ratio. At (80...
Torud-Chah Shirine magmatic arc is located in south of Semnan. This arc is composed of Cenozoic volcanic, pyroclastic and intrusive rocks. The Kuh-Zar in manning province of Bagho is outstanding with Cu-Au mineralization. Mining is restricted to hydrothermal alteration zones in the area. Alteration zones includes propylitic, phyllic, advanced argillic and silicic. The rare association of tourma...
