Study on CO2 Emission Characteristics of China VI Heavy Duty Diesel Engine [PDF]

open access: yesE3S Web of Conferences, 2022
CO2 emission control is of great urgency, and the decrease of heavy-duty diesel engines’ CO2 emission is one of the significant methods to reduce CO2 emission. This paper uses a full-flow constantvolume dilution sampling system to experiment on the China

Carbon Pricing and the Elasticity of Co2 Emissions [PDF]

open access: yesSSRN Electronic Journal, 2020
We study the impact of carbon pricing on CO2 emissions across five sectors for a panel of 39 countries over 1990-2016. Using newly constructed sector-level carbon price data, we implement a novel approach to estimate the changes in CO2 emissions associated with (i) the introduction of carbon pricing regardless of the price level; (ii) the ...

Plastic futures and their CO2 emissions

open access: yesNature, 2022
Plastics show the strongest production growth of all bulk materials and are already responsible for 4.5% of global greenhouse gas emissions1,2. If no new policies are implemented, we project a doubling of global plastic demand by 2050 and more than a tripling by 2100, with an almost equivalent increase in CO2 emissions.

Photoreduction of CO2 in the presence of CH4 over g-C3N4 modified with TiO2 nanoparticles at room temperature

open access: yesGreen Energy & Environment, 2021
CO2 reduction under simulated sunlight over photocatalysts has become an attractive researcher area recently. In this work, carbon nitride compounds modified by TiO2 nanoparticles (TNPs) have been used for the photoreduction of CO2 in the presence of CH4

Artificial neural network prediction of transport properties of novel MPDL-based solvents for post combustion carbon capture

open access: yesEnergy Reports, 2022
Novel N-methyl-4-piperidinol (MPDL)-based solvents have been considered as high potential solvents for post combustion carbon capture, especially for power generation industry. To comprehensively investigate the CO2 absorption-regeneration performance of

Comparative mass transfer performance of CO2 absorption using highly-concentrated AMP-PZ-MEA ternary amines solvent

open access: yesEnergy Reports, 2023
Mass transfer performance of CO2 absorption is based on selecting an effective amine solvent, hence, an examination of the overall mass transfer coefficient (KGav) and CO2 removal efficiency, is significant for obtaining the most favorable CO2 capture ...

CO2/SO2 emission reduction in CO2 shipping infrastructure [PDF]

open access: yesInternational Journal of Greenhouse Gas Control, 2018
Abstract There is an increased focus on the reduction of anthropogenic emissions of CO2 by means of CO2 capture processes and storage in geological formations or for enhanced oil recovery. The necessary link between the capture and storage processes is the transport system.

How Does Land Urbanization Promote CO2 Emissions Reduction? Evidence From Chinese Prefectural-Level Cities

open access: yesFrontiers in Environmental Science, 2021
The process of land urbanization may result in a great change in land use structure, land use intensity, and efficiency, which could further lead to an increase in carbon dioxide (CO2) emissions.

CO2 emissions and their changes with H2O emissions, soil moisture, and temperature during the wetting–drying process of the soil mixed with different biochar materials

open access: yesJournal of Water and Climate Change, 2022
Biochar is an organic regulator that improves crop yield by regulating soil properties. In addition, this organic regulator is also effective in reducing CO2 emissions from soil.
