Less than 1000 ppm CO2 in the background gas 311, 316, 317, 318, 3160 B-2C 3000T series L-2C More than 1000 ppm up to CO2 in the background gas All trace oxygen instruments A-2C Note: To use the A-2C or B-2C sensor in a 3000T series instrument, adapter part number B663...
Fixed data quality issues in CO2 emissions indicators (emissions less than 0, missing data for Eswatini, ...). Replaced all input CSVs with data retrieved directly from ourworldindata.org. 2021-02-08: Updated this dataset with the latest annual release from the Global Carbon Project. ...
The project adopts a two-phase absorbent with low energy consumption to capture CO2, and the regeneration energy consumption of such absorbent is less than 2.4 gigajoule per tonne, reaching the advanced level globally. The captured CO2 is then used to produce industrial products with wide applicatio...
The role of China in global CO2emissions has been widely considered in existing studies. Many studies focus on the impacts of structural changes in the final demand of China on global or regional CO2emissions10,11,12,13,14. Specifically, scholars have taken into account the influence of China...
less than that of CO2, a substantial reduction in their emissions would measurably reduce the impact of human activity on our climate. And as non-CO2greenhouse gases tend to have a shorter atmospheric lifetime than CO2, the response of the climate system to emissions cuts in the former would...
There was no apparent change in the relationship between pressure and the swelling factor before and after the supercritical pressure around 8 MPa, thus CO2 dissolution and oil swelling were not so sensitive pressure less than 10 MP. The swelling coefficients of CO2 in the heavy and medium oils...
“Decoupling occurs when the growth rate of an environmental pressure is less than that of its economic driving force (e.g., GDP) over a given period.”49 Numerous studies, such as Juknys,50 Marques et al.,51 and Akizu-Gardoki et al,52 have proposed different indices to quantify the ...
10 GPa with errors less than 2%in density.In order to integrate all the simulation results of this study and previous studies [Zhang and Duan,2005a,2005b]and the experimental data for the calculation of volumetric properties(volume,density,and excess volume),heat properties,and chemical ...
hypothesis to explain a more efficient biological carbon (C) pump and the associated drawdown of atmospheric CO2. Yet, modelling focussed on the high latitudes has sequestered less than 10 ppm of atmospheric CO2via Fe fertilisation5,6,7and indicates that additional biological mechanisms are required...
given in this study, we compared our results with estimates of other professional institutes or research groups, as shown in Fig.7. It illustrates that our estimates for cement-related emissions of China are lying in the middle range, close to the official estimates, with less than 1% ...
