Slow pyrolysis, a widely recognized thermochemical technique, is employed to produce biochar usually under inert atmospheres. Recently, there growing interest in utilizing CO2 as carrier gas during pyrolysis an alternative atmospheres, aiming modify the resulting pyrolytic products and make them suitable for different applications. This study investigated compared impact of atmosphere with N2 on food waste, rice husk, grape tree branches waste via slow at temperatures 400, 500, 600 °C 5 15...
Chronic total occlusion (CTO) percutaneous coronary interventions have more complications due to intrinsic complexity of procedure which is further compounded by ambiguity proximal cap. If the ambiguous cap CTO at ostial left anterior descending artery (LAD), impact huge as area myocardium risk significant. Hence, while treating LAD or circumflex (LCX), special attention must be given prevent minimize inflow injuries like dissection intramural hematoma (IMH) main (LMCA) and its branches. In...
In the current study, sugarcane bagasse-derived biochar catalysts were synthesized by doping with metal-free heteroatoms including nitrogen, phosphorus, oxygen, and boron their efficacy was tested for catalytic co-pyrolysis of walnut shells (WS) palm oil fatty acid distillate (PFAD) using Py-GC/MS. The catalysts' properties effectiveness on co-pyrolytic bio-oil (overall product distribution, selectivity towards aliphatic aromatic hydrocarbons, carbon number ranges) extensively examined....
Bioleaching of the converter slag was studied on bench scale using Thiobacillus ferrooxidans, an iron oxidising bacteria, for recovery valuable metals at room temperature. Parameters such as particle size, pH, pulp density, Fe(II)/Fe(III) ratio and amount Fe(II), additives etc. were optimised to treat slag. The recoveries from under sterile bio-assisted leaching conditions found 80.0% 99.0%Cu in 1920 h, 18.0% 22.0% Ni 1680 h 16.0% 30.0%Co 1200 respectively. variance leach mainly due...
Abstract For the exploitation of a low grade tungsten deposit Tapaskonda, A.P., India containing 0.1-0.16% WO3, preconcentrate with 13.06% WO3 was produced by physical beneficiation. This concentrate ferberite along small amount wolframite minerals treated following two routes viz. soda ash roast-leach and alkali pressure leach processes. The parameters such as time, temperature, concentration alkali, etc., have been studied to optimise recovery tungsten. In roast -leach process about 89%...
Abstract Torréfaction is a well-known method to thermally treats biomass at lower temperature range (200 300 °C) under inert atmosphere. However, the continuous supply of pure gas on large scale resist commercialisation this process. To investigate effect combustion (flue gas) torrefaction performance oil palm fronds leaves (OPFL) and stems (OPFS), both samples were torrefied 200 °C for 30 min in vertical tubular reactor atmosphere produced from wood pellets nitrogen (inert) gas. The major...
