Pyrolysis of biomass converts all components into liquid, gaseous, and solid products without the need for component separation. However, composition liquid from lignocellulosic is usually complex difficult to upgrade. Slow pyrolysis de-oiled rapeseed cake, an agricultural waste pressing process, was carried out fuel production. The maximum yield bio-oil obtained 51.6 wt.% under optimized conditions. HHV bio-oil, containing mainly acids, hydrocarbons, esters, alcohols, 32.82 MJ·kg−1, similar that bio-diesel, be promising in downstream upgrading because properties such as higher caloric value, limited moisture content, well neutral pH were close commercial bio-diesel. gaseous fraction consisted CO, C1, C2 H2, CO2, corresponding LHV reached 7.63 MJ·Nm−3. bio-chars declined 41.8 at 400 °C 28.8 800 °C, whereas varied 29.03 MJ·kg−1 30.14 comparative coal, indicating a candidate fuels or functional carbon. product shows promise feedstock producing high-quality fuel.

Biochar as a by-product of the carbonization biomass has an inherent potential to modify acidic soils due its alkaline nature. To explore mechanism and effectiveness biochar, case study was conducted on severely from six fields under tea cultivation in subtropical zone, comparing rice husk biochars, three rates (B5, B10, B15 t ha−1), CaCO3 conventional liming practice. The results showed increases pH 71.5%, 52.7%, 30.6%, 29.7% B15, B5, CaCO3-treated compared control. On average, B10 treatments resulted highest organic matter with 12.3% 9.7%, respectively. caused 196.6%, 173.4%, 129.7%, 100.9% base saturation control, Also, after application B5 treatments, effective cation exchange capacity increased by 191.4%, 112.1%, 39.5%; however, 20.1% decrease. Overall, applying biochar provides adequate negative charges well-extended specific surface area pore volume, which cause absorption additional Al+, resulting ameliorating soil pH. proper could notably be more improving than practices such overuse CaCO3. In this regard, evaluating various biochars terms feedstock, pyrolysis conditions, modification scenarios merits in-depth research future studies.

Climate change cause extreme weather effects with temperature increases and drops in humidity, such as drought heatwaves, which will lead to more evaporation arid semi-arid lands. The application of biochar made from crop straw without burning farmland can effectively improve the water retention capacity soil. A testing program has been carried out a climate simulation laboratory study different biochars on cracking soils due drying. Biochar wheat (WS), corn (CS) rice (RS) is produced at pyrolysis 500℃. Thermogravimetric analysis elemental are obtain properties biochar. Five percent WS, CS RS by weight added acidic Digital camera digital image processing technology used analyze crack morphology samples during evaporation. results indicate that highest ash content (32.5 %), volatile solid (25.36 %) WS fixed carbon (55.38 %). final contents soil 132.3 %, 101.0 20.7 % respectively higher than Moreover, reduce degree cracking. addition 9.21 16.57 7.46 respectively. contains total cellulose RS, so best choice ability. Therefore, helps optimize while avoiding environmental pollution burning.

Biochar can serve as a soil amendment to immobilize nitrogen (N) and reduce N leaching from cropland without negative effect on crop yield. However, the interaction of biochar application irrigation regimes status (N retention loss) yield is rarely reported in open perennial vegetable field. A two-years field trial (transplanting first year consecutive growth second year) was conducted citron daylily cropping system sandy brown alluvial soil. Two rates (0 30 t ha−1) three (CDI, conventional drip irrigation; WSDI, water-saving with 80% full quota; APRDI, alternate partial root-zone quota) were included. The response both varied across planting years for daylily. After year's harvest, APRDI enhanced flower bud by 18–28% compared CDI likely due improved nitrate use efficiency evidenced lower surface (0–20 cm) post-harvest. resulted reduction 27% under APRDI. Additionally, WSDI reduced yields, decreased TN sub-surface layer (20–50 9–19% comparison other two regimes, resulting higher concentration solution (14–28%) thus an increased risk leaching. after harvest year, there no variations induced regimes. Irrigation exhibited limited influence status, while mitigated decline 0–50 cm enhancing organic capacity nearly 16–85%. Furthermore, lowest suggested We conclude that combining regime could help retain N, decrease leaching, enhance total years. Therefore, this approach recommended sustainable management long-term crops.
