Why biochar has to be hydrophobic?5 answersBiochar needs to be hydrophobic primarily for two reasons. Firstly, hydrophobic biochar exhibits excellent oil sorption capacity, making it effective for environmental remediation by adsorbing leaking oil and preventing further spread on water surfaces. Secondly, enhancing the hydrophobicity of biochar can improve its waterproof ability when used in biochar-amended soil covers, reducing rainwater infiltration into landfills and minimizing leachate production. Various methods such as torrefaction followed by modification with hexadecyltrimethoxysilane or silane coupling agents have been explored to achieve hydrophobicity in biochar, leading to improved performance in terms of oil adsorption, environmental sustainability, and waterproofness. Therefore, ensuring biochar is hydrophobic is crucial for its effectiveness in both environmental applications and landfill management.
What is Biochar?4 answersBiochar is a black carbon produced through the process of slow pyrolysis from renewable biomass. It has the ability to improve the physical, chemical, and biological properties of soil, leading to increased crop yield and productivity. Biochar can lower bulk density, improve porosity, water infiltration, and water holding capacity of soils. It also darkens soil color, moderating soil temperature. Additionally, biochar enhances cation exchange capacity, increases soil pH, improves nutrient supply and uptake, reduces nutrient leaching losses, and captures NH3, thus improving nutrient availability. It can also remediate soils contaminated with heavy metals and organic pollutants. Biochar facilitates microbial colonization, enhances soil microbial biomass carbon, enzyme activity, and the activity of mycorrhizal fungi. It is used in agriculture as a soil amendment for plant growth promotion, improving soil fertility, and plant disease suppression. Biochar can also be used as a peat water filtration media, effectively removing pollutants.
What are good qualities of charcoal?4 answersGood qualities of charcoal include density, mechanical strength, reactivity, ease of ignition, rapid formation of embers and flames, fast preparation of grilled food, affordability, low moisture content, low ash content, low friability, and high heat production.Charcoal made from certain materials such as eucalyptus and coconut shell have been found to have desirable characteristics.The production process of charcoal briquettes involves aerobic burning at high temperatures, grinding, mixing with a binder such as starch, and achieving a specific particle size range.Charcoal is also known for its low sulfur, low mercury, low nitrogen, and low ash content, making it an attractive renewable fuel option.Additionally, charcoal can have a large surface area and electrical conductivity comparable to graphite, making it a good adsorbent and a semimetal.
What are the effects of biochar on soil properties?5 answersBiochar application has positive effects on soil properties such as pH, surface area, cation exchange capacity, and nutrient content, leading to improved soil fertility and crop productivity. It has been found to have significant effects on available K, P, CEC, EC, and N in soils contaminated with heavy metals like chromium (Cr), indicating its potential for soil health improvement and remediation of polluted soils. Biochar also reduces the concentrations of exchangeable metals in the soil, including Al, Fe, Ni, Cd, Pb, and Zn, thereby reducing the risk of metal contamination in agricultural products. Additionally, biochar can alter soil thermal conductivity, capacity, and diffusivity, with a significant reduction in thermal conductivity and diffusivity observed under consistent bulk-density conditions. The effects of biochar on soil thermal properties are influenced by factors such as biochar particle size, application rate, and soil moisture content.
What are the properties of biochar?5 answersBiochar is a carbon-rich material produced through pyrolysis of organic feedstocks. It has various properties that make it suitable for different applications. Biochar can hold and release water within its porous structure, making it useful for soil amendments and improving soil health and productivity. The physical, hydrological, and mechanical properties of soils can be significantly altered by the addition of biochar, but the impact can vary depending on the characteristics of the biochar and soil. Biochar can also exhibit superhydrophobic behavior, with high water contact angles and self-cleaning properties. In terms of its use as a supplementary cementitious material, biochar can improve the compressive and flexural strength of concrete, as well as its durability. Additionally, biochar derived from antibiotic mycelial residue has the potential to immobilize heavy metals and reduce their leaching, making it a valuable resource for waste disposal.
What are the characteristics of charcoal ash?2 answersCharcoal ash has higher pH, electrical conductivity (EC), and calcium carbonate equivalent (CCE) compared to firewood ash. It also contains higher levels of arsenic (As), copper (Cu), magnesium (Mg), and zinc (Zn). The dominant minerals in charcoal ash are calcite, calcium oxide, and calcium manganate (CaMnO3). Aqua regia and vinegar are suitable for extracting calcium (Ca), acidic solutions for magnesium (Mg), and H2SO4 and aqua regia for phosphorus (P). Charcoal ash may contain trace elements with varying bioavailability, which may not necessarily be taken up by plants after field application.
