摘要

In this present study, initially, activated carbon is derived from eucalyptus wood utilizing a single-stage activation method. Then, the developed sample is characterized by different characterization and analytical techniques such as (i) proximate analysis, (ii) ultimate analysis, (iii) Brunauer–Emmett–Teller (BET) surface area analysis, (iv) Barrett-Joyner-Halenda (BJH) pore size analysis, (v) Scanning Electron Microscopy (SEM) surface morphology analysis, (vi) Fourier transform infrared spectroscopy (FTIR) surface chemistry analysis, and (vii) Thermogravimetric Analysis (TGA) thermal stability analysis to evaluate its surface features and ensure suitability as an adsorbent for carbon capture. After that, the characterized adsorbent is filled inside the capture unit and coupled to a test engine. This study uses a computerized diesel engine, and the test engine is operated by employing two distinct test fuels: (i) petro-diesel (D100) and (ii) 80% Jatropha methyl ester (JME) + 20% D100 (JME20). The adsorbent performance is examined in terms of CO2 adsorption, and the adsorbent sample’s adsorption parameter is discussed. The results obtained from experimental findings are compared with the adsorbent performance and fuels used in a test engine. The experimental test results showed that about 44% and 38% of CO2 emissions are captured for D100 and JME20 fuel operations, respectively.
