Removal of sulphur from diesel was carried out by using by using coconut shell activated carbons. Fixed bed adsorption experiments was performed for determination of break through curve at room temperature. Experiments were carried out with different flow rates .initial concentration, and bed heights. The experiments of three different bed height ,100 mm ,200 mm,and 300 mm with three different flowrate 1.6 ml/min,3.6 ml/min and 5.6 ml/min.Also experiments with three different sulphur concentration334.5 ppm, 167.25ppm and 86.625 ppm. Adsorption of sulphur from diesel is presented in the form of breakthrough curves (i.e. C/Co Vs t) In almost all the experiments, the exit conc.at 0 time was more than 30%.(C/C0).so breakthrough point as such can not be found. The breakthrough curve was different than typically observed in packed bed experiment so exaution time was considered and analysed for variation in various parameter. The performance of fixed bed in the form of breakthrough curves were obtained and tested using different kinetic models like Thomas, Adam-Bohart, Yoon-Nelson .Adsorption capacity (mg/g) was found from the models. The constants obtained from the models can be utilized for designing the industrial scale fixed bed. The performance of the regenerated sorbent bed was tested and found similar to that of the fresh adsorbent bed indicating the usefulness of the developed regeneration process.
