Effect of sodium sulphate on the hydration of granulated blast furnace slag blended portland cement

2013-11-30T16:41:59Z

Title: Effect of sodium sulphate on the hydration of granulated blast furnace slag blended portland cement Authors: Singh, Neelam; Rai, Sarita; Singh, N B Abstract: The effect of 4 wt% Na₂SO₄ on the hydration of granulated blast furnace slag (GBFS) blended portland cement (1:1, referred to as the blended cement here) has been studied. Na₂SO₄ accelerates the hydration in addition to activating the granulated blast furnace slag at the same time. Activating action may be explained by breaking of different bonds at the surface of the slag. Page(s): 110-113

Kinetics of photocatalytic degradation of textile dye reactive red 2

Title: Kinetics of photocatalytic degradation of textile dye reactive red 2 Authors: Shankar, M V; Neppolian, B; Sakthivel, S; Arabindoo, Banumathi; Palanichamy, M; Murugesan, V Abstract: The photocatalytic degradation of the dye, reactive red 2 has been investigated in aqueous heterogenous solution containing TiO₂ as photocatalyst in a batch reactor. The disappearance of the dye follows approximately pseudo-first order kinetics according to the Langmuir-Hinshelwood model. The addition of optimal amount of hydrogen peroxide and potassium persulphate enhances the degradation rate of the dye. The presence of sodium carbonate and sodium chloride hinders the photocatalytic degradation. TiO₂ has been experimentally found to be highly efficient photocatalyst in the degradation of textile dyes and hence there is a great potential in the treatment of effluents from textile industries by photocatalytic degradation technique.

Treated fly ash : A potential catalyst for catalytic cracking

2013-11-29T16:43:33Z

Title: Treated fly ash : A potential catalyst for catalytic cracking Authors: Ojha, Keka; Pradhan, Narayan C Abstract: Fly ash from a Thermal Power Plant was converted to zeolite by alkali fusion followed by hydrothermal treatment. The formation of zeolite was confirmed by X-ray diffraction and scanning electron microscopy. The performance of the prepared zeolite as cracking catalyst was tested by carrying out cracking of a heavy crude residue. Cracking of the same feed was also carried out with raw (untreated) fly ash and commercial 13X zeolite. At 11 wt% catalyst loading, temperature 380°C and atmospheric pressure, the feed conversions to lighter products (bp ≤ 250°C) obtained were 35.6%, 58% and 58% with raw fly ash, treated fly ash and commercial zeolite, respectively, as the catalyst.
