Title: Sintering 2000: Conference Report
Authors: Upadhyaya, G S
Abstract: The presentations made during Sintering 2000
(7<sup>th</sup> International Conference on Sintering), organised under the auspices
of the International Institute for the Science of Sintering (IISS), Belgrade, are reviewed here.
The conference was divided into 15 Technical Sessions for the invited and contributed
papers. The sessions were grouped as: Fundamentals; Advanced
Processing Methods; Ferrous Materials; Non-Ferrous/Intermetallic
Materials; Oxide Ceramics; Non oxide Ceramics; Cermets; Ceramics Matrix Compounds;
and, Electronic Materials

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% Na<sub>2</sub>SO<sub>4</sub>
on the hydration of granulated blast furnace slag (GBFS) blended portland cement
(1:1, referred to as the blended cement here) has been studied. Na<sub>2</sub>SO<sub>4</sub>
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.

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
TiO<sub>2</sub> 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. TiO<sub>2</sub> 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.

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.
