Optimization of biochar preparation process and carbon sequestration effect of pruned wolfberry branches

Abstract: Pruned wolfberry branches are abundant and suitable raw material for biomass conversion. It would be helpful in determining the preparation conditions of biochar of pruned wolfberry branches for carbon sequestration and emission reduction. Based on the findings, the effects of temperature on yield and stable carbon content were higher than those of holding time. The potential of carbon sequestration of biochar grown by wolfberry branches and returned to the soil was investigated by the RSM, and the holding time was 2 h. Biochar was found to contribute to carbon sequestration and emission reduction in Qinghai province, but a reduction of carbon sequestration and emission reduction could be achieved annually if all biochar were applied to soil; 64. 56 m3 in the atmosphere and 34. 42 t of carbon dioxide were reduced annually from combustion in the atmosphere; 34. 42 u00d7 10 3 t of carbon could be reduced annually; 47. 56 tonne of carbon dioxide u00d7.

Geological Sequestration of Carbon Dioxide in Depleted Gas Reservoirs

Abstract The aim of this paper is to investigate the effects of phase behavior on the sequestration of CO2 in depleted gas reservoirs. Both major goals can be achieved by carbon dioxide sequestration in depleted and abandoned gas reservoirs. Carbon dioxide had a drying effect on wet and retrograde gas mixtures as well as a wetting effect on dry gas, according to simulation results. The results for retrograde gas condensate were dependent on the composition of reservoir fluids at abandonment conditions.

Long-Term Field Biochar Application for Rice Production: Effects on Soil Nutrient Supply, Carbon Sequestration, Crop Yield and Grain Minerals

The availability of soil N, P, and K was raised by 11. 6 percent and Mn by 20. 7 percent in the surface soil, leading to a marginal but insignificant decrease in grain Fe and Mn. The grain Zn concentration was not affected by the grain Zn concentration, although the intermediate and high doses significantly increased the soil available Zn by 96. 2% to 227. 9%. Soil total C and N increased linearly with biochar application for the surface soil, but only where biochar was used. In conclusion, with high soil C sequestration capacity, improving the soil macronutrient and Zn fertility, but caution is advised as higher doses of biochar may lead to a decrease in soil Fe and Mn and a reduction in grain Cu concentration.

The Function of Gas-Water Relative Permeability Hysteresis in the Sequestration of Carbon Dioxide in Saline Formations

Abstract. As an alternative to atmospheric venting of carbon dioxide, the injection of carbon dioxide into saline formations for the purpose of limiting greenhouse gas emissions has been suggested. To date, investigations into the subsurface interactions of injected CO2 in saline formations have concentrated on two main areas: dissolution of CO2 into saline formation waters and the geochemical/mineralization effects of the injected CO2 on the formation rock matrix. It has been suggested that trapping CO2 as a persistent phase of continuous sequestration of CO2 as a result of water imbibation is another method of permanent sequestration of CO2. This paper will discuss how gas-water relative permeability hysteresis could contribute to the success of a geological CO2 sequestration scheme. This process is similar to that of aquifer encroachment on depleted gas reservoirs where water traps gas along its course. During the injection phase of a geological CO2 sequestration scheme, the movement of CO2 is dominated by a drainage relative permeability state, as CO2 displaces brine, the formation's wet phase. At most reservoir conditions, more buoyant than brine, and so injected CO2 would tend to migrate up-dip along the top seal. Imbibition relative permeability dominates at the end of the migrating plume as water imbibes behind the migrating plume trapping CO2 as a residual phase. Trapping CO2 as a remaining phase is shown to have a positive effect on the success of a geologic sequestration scheme.

Effects of recultivation on soil organic carbon sequestration in abandoned coal mining sites: a meta-analysis

Abstract Opencast coal mining results in a significant loss of soil organic carbon, which may be restored by recultivation. In 51 studies, We, therefore, investigated the relationship between SOC stock changes in abandoned coal mines and the recultivation process, soil properties, climate, and time under recultivation. The key factor in encouraging SOC sequestration is soil texture, which is primarily due to clay content. According to 44% and 67% responses, U2212 1 and 0. 8 Mg ha u2212 1 at 0. 4 Mg ha u2212 1 and 1 u2212 1 was the most effective environment for SOC sequestration at 0. 4 Mg ha u2212 1 and 0. 8 Mg ha u2212 1 a u2212 1 and u2212 1 a u2212 1 a u2212 1 a u221212 1 a SOC sequestration at a he a he ha a u22121212121212121212121212121212121212121212121212121212121212121212.

Carbon Dioxide Sequestration in Coal Seams: A Parametric Study and Development of a Practical Prediction/Screening Tool Using Neuro-Simulation

Consequently, the widespread use of fossil fuels has measurably raised the total load of one of the company's byproducts, carbon dioxide, in the atmosphere, as well as concerns about global warming's effects on global climate change, which has prompted the development of various methods and policies aimed at lowering the concentration of this green-house gas in the atmosphere. CO2 preferentially sorbs to coal, replacing the coalbed methane that can be manufactured and sold to reduce the costs of sequestering CO2; a source of coalbed methane; and a repository for sequestration of CO2 are two examples; and a repository for sequestration of CO2 are two examples among unmineable coal seams; and a repository for CO2 sequestration. PSU-COALCOMP, a simulational coalbed methane reservoir simulator, is used to model the primary and enhanced recovery of coalbed methane by CO2 injection for a variety of coal properties and operational scenarios in this study. The simulation findings include the cumulative amount of CO2 injecting and retaining in the coal seam, the cumulative amount of coalbed methane produced, as well as the CO2 breakthrough time. A CO2 prediction tool is created based on the results, findings, and analyses obtained from the simulations conducted during the parametric study, based on the findings, and analyses from the parametric study's experiments, a CO2 prediction tool is created using neurosimulation techniques. This tool is used to determine the results of a variety of coal-seams and other manufacturing schemes within an acceptable margin of error and in a timely and cost-effective manner.

The Significance of Property Rights in Biotic Sequestration of Carbon

This chapter discusses the role of property rights in the creation of appropriate legal frameworks for biotic carbon sequestration in this chapter. Building on earlier, larger-scale, preliminary study, two key issues will be investigated, including establishing a property rights framework for sequestered carbon and sequestered carbon, and sequestered carbon.

Carbon sequestration

Abstract Abstract: Although traditional ecology textbooks mainly address the short-term carbon cycle, life has been instrumental in the geological long-term carbon cycle through processes such as silicate weathering, the role of life has been key in the geological long-term carbon cycle. Large leaves will develop as a result of lower CO2 levels and terrestrial plants, according to arguments, co-evolution of CO2 levels and terrestrial plants evolved between CO2 levels and terrestrial plants u2014. Without the effects of life, the Earth appears that without life on Earth, our planet would now have a temperature that would prevent the survival of eukaryotic life.

Carbon Sequestration in Fine Aroma Cocoa Agroforestry Systems in Amazonas, Peru

Using agroforestry equipment that can capture and store atmospheric CO2 is one way to combat climate change, according to the establishment of agroforestry systems that can capture and store atmospheric CO2. These cocoa AFSs were limited to three age groups: young cocoa trees aged 8 to 15, middle-aged cocoa trees between 16 and 29, and mature cocoa trees aged 30 to 40 years old, with minimum area of 1. 5 ha divided into three age groups: young cocoa trees between 8 and 15 years old, middle-aged cocoa trees between 16 and 29 years old, and mature cocoa trees between 16 and 29 years old. However, no significant differences were found for any of the age groups in young cocoa tree systems and adult cocoa plants; however, no significant differences were found in any of the age groups. In comparison to middle-aged cocoa systems and young cocoa systems, however, no statistically significant differences were found.
