An innovative approach to develop microporous activated carbons in oxidising at...
Suhas; Carrott, P. J. M.; Ribeiro Carrott, M. M. L.; Singh, R.; Singh, L. P.; Choudhary, M.The aim of the study was to investigate a rather oxidising atmosphere such as air for the development of a microporous activated carbon from demineralised kraft lignin. Demineralisation of lignin makes the precursor low in reactivity and hence can allow the use of more oxidising atmospheres. Control of the activation conditions allowed development of microporous activated carbons with type I N2 adsorption isoth...

Cellulose: A review as natural, modified and activated carbon adsorbent
Suhas; Gupta, V. K.; Carrott, P. J. M.; Singh, R.; Chaudhary, M.; Kushwaha, S.Cellulose is a biodegradable, renewable, non-meltable polymer which is insoluble in most solvents due to hydrogen bonding and crystallinity. Natural cellulose shows lower adsorption capacity as compared to modified cellulose and its capacity can be enhanced by modification usually by chemicals. This review focuses on the utilization of cellulose as an adsorbent in natural/modified form or as a precursor for act...

Adsorption of n-Pentane and iso-Octane for the Evaluation of the Porosity of De...
Ribeiro Carrott, M. M. L.; Russo, P. A.; Carvalhal, C.; Carrott, P. J. M.; Marques, J. P.; Lopes, J. M.; Gener, I.; Guisnet, M.; Ramôa Ribeiro, F.Adsorption of n-pentane and 2,2,4-trimethylpentane at 298 K was carried out in order to characterize the porosity of a series of HBEA dealuminated zeolites. The HBEA samples were prepared from a calcined parent sample by steaming, by treatment with hydrochloric acid and by treatment with ammonium hexafluorosilicate (HFS) solutions. The comparison of the adsorption results with those previously obtained by nitro...
