Cost-effective biomass drying is a key challenge for energy recovery from by direct combustion, gasification, and pyrolysis. The aim of the present study was to optimize process using hot air convection (HA), infrared (IR), combined systems (IR-HA). specific consumption (SEC) decreased significantly increasing temperature convective drying, but higher velocities increased SEC. Similarly, velocity in dryer resulted significant increase lowest SEC recorded at 7.8 MJ/kg an 0.5 m/s IR intensity...
Geological CO2 sequestration in basalt formations represents a promising approach to mitigate climate change through secure carbon dioxide storage via mineral carbonation. This study investigates dissolution, precipitation, and their influence on pore structure during batch experiments under controlled conditions (P: 8 MPa, T: 100 °C). The were conducted an autoclave system containing brine, where sample (2 cm width 9 height) was partially submerged mimic CO2-brine boundary...
Ex-situ mineral carbonation, utilizing industrial by-products or natural calcium- and magnesium-bearing rocks, presents a promising avenue for CO2 removal. Both calcium magnesium can form carbonates independently in conjunction. While is significant mineralization source, its presence negatively influence carbonate precipitation crystal stability when co-precipitated with CaCO3. This study investigates the effects of varying Mg2+/Ca2+ molar ratios on carbonation process under controlled...
Direct mineral carbonation (MC) is used to mitigate carbon dioxide (CO2) emissions. This method has the great advantages of reducing amount industrial residues and creating valuable materials by incorporating CO2. Waste gypsum, waste including flue gas desulfurization (FGD) gypsum (25.27–53.40 wt% CaO), phosphogypsum (30.50–39.06 CaO) can be for direct MC (conversion rate up 96%). Mineral converts into calcium carbonate (CaCO3), which recycled during desulfurization. Furthermore, ammonium...
In this investigation, a laboratory-scale study to extract copper (Cu) from its oxide ore (0.425–11.2 mm particle size) was conducted using varied sulfuric acid (H2SO4) concentrations (0.05–0.5 M) as lixiviant. Through physicochemical and mineralogical analysis of real field samples the Almalyk mine heap site (Tashkent, Uzbekistan), malachite identified Cu-bearing mineral. Extraction rates were analyzed according size concentration. The Cu extraction with smallest (in 24 h) between 76.7%...
Column tests of a sulfate reducing bacteria (SRB) bioreactor were conducted to determine the design factors for sulfate-rich mine drainage. Various substrates applied bioreactor, including cow manure and its mixture with mushroom compost, rice straw limestone as subsidiary materials. This procedure provided removal efficiency up 82% total sulfur (70%), compost (10%) (20%), higher efficiencies observed after 2 days retention time. In downflow condition flow direction, oxygen supply...
The inhibiting effectiveness of silicate- and phosphate-based surface-coating agents (Na 2 SiO 3 KH PO 4 ) to the oxidation iron sulfide minerals was investigated using pyrite rock samples containing minerals. film formed with both identified by surface analysis. surface, layered iron-silicate or -phosphate, inhibited (77 23%, respectively) under accelerated oxidizing conditions H O , as measured based on SO 2− concentration in leachate. Oxidation coated -phosphate reduced up 54 33%,...
