Wooden Charcoal as Adsorbent Material to Capture CO2 in the CI engine Exhaust Fueled with Different Blends of Biodiesel | Chapter 4 | Science and Technology: Developments and Applications Vol. 9

A study on reducing the buildup of carbon dioxide (CO₂) in the atmosphere is now necessary due to the issues with global warming and climate change brought on by greenhouse gas emissions, especially CO₂. Carbon dioxide capture and storage (CCS) by absorption is a straightforward and superior technique for reducing CO₂ emissions, despite the fact that several CO₂ capture technologies have been developed for post-combustion processes. This study aims to reduce CO₂ emissions from internal combustion engines by employing woody charcoal as an inexpensive adsorbent material. This study also encourages the transition to renewable and non-edible biofuels by demonstrating the potential of biodiesel blends made from cottonseed and neem oil. The study also explores CO₂ collection methods using adsorbents to assist governments and companies in implementing cleaner energy sources. A single cylinder, four-stroke, computerized water-cooled, diesel engine with a 3.5 kW rated power was used to test the emission characteristics of the cotton seed oil and neem oil blends by varying the engine loads. This study was done for both with and without CCS. One hundred grammes of wooden charcoal was utilized in this analysis. According to the results, when operating at full load, the CCS with wooden charcoal adsorbed CO₂ emissions by 11.4%. Further, the CO and HC emissions were also adsorbed by 12% and 13.75%, respectively. However, because of the back pressure, the brake thermal efficiency for CCS is somewhat reduced.

Effect of Biochar on Soil CO2 Fluxes from Agricultural Field Experiments in Russian Far East: A Recent Study | Chapter 3 | Current Topics in Agricultural Sciences Vol. 3

 Agricultural soils emit a significant amount of greenhouse gases. Biochar is a soil improver that sequesters carbon when applied to the soil. Biochar has a low rate of decomposition compared to the initial biomass, allowing for a longer residence time in the soil than other organic supplements. Varied combinations of soil and meteorological conditions, as well as biochar, provide different research outcomes. The goal of our study was to determine the effects of applying 1 kg/m2 and 3 kg/m2 biochar to clay soils on CO2 flow in field tests across two cropping seasons in the Russian Far East. Biochar significantly reduces the cumulative flow of soil CO2 when compared to untreated field plots, according to the data. In the 2018 season, the application of 3 kg/m2 of biochar resulted in the largest reduction in soil CO2 emissions (28.2%), whereas the application of 1 kg/m2 resulted in the greatest reduction in cumulative CO2 flow (57.7%) in 2019. During the 2018 growing season, there was a correlation between a drop in the value of the cumulative CO2 flow and an increase in the biomass grown in the examined areas of agricultural crops.
