Abstract
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.
期刊介绍：
Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments.
Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation.
Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
