Regeneration of Bleaching Clay Waste by Chemical Activation with Chloride Salts

Abstract: Spent bleaching earth (SBE) was regenerated by chemical activation with low cost and low pollution chlorides as activating agents. Under the conditions of activation temperature of 600d egrees C and holding time of 1 h investigated, results show that fresh bleaching earth and regenerated bleaching earth are type IV with hysteresis loops corresponding to type H3 from nitrogen adsorption-desorption isotherms, indicating slit-shaped mesoporous structure. It is also found that the effect of the regeneration treatm… Show more

“…The precursor was then impregnated with potassium chloride and finally regenerated in the conditions of constant ramp rate of 10 • C min −1 under N 2 flow of 300 cm 3 min −1 , activation temperature of 600 • C, and holding time of 1 h [5]. The main physical properties are given in Table 1 [5].…”

“…As experimental comparisons, Table 1 also shows the main physical properties of ABE. Obviously, these adsorbents are characteristic of mesoporous structures, showing that the sample possesses a major peak of pore (slit) widths at about 4.0 nm and a majority of the pores in a broad range at widths of 3.0-20.0 nm [5]. H 2 SO 4 and NaOH were used to adjust initial pH value of aqueous solution.…”

“…Physical activation with steam to get high micropore 12 and irradiating with gamma rays have been documented in the literature 13 . Activating clay using simultaneous chemical as well as physical activation is extensively reported [14][15][16] . We report on the use of NaOH and KOH as intercalating agents to pre baked clay, separately.…”
