Recycled chicken eggshells after calcination have been used as a nonconventional heterogeneous catalyst for biodiesel synthesis from karanja oil from the pongam tree (Pongamia pinnata). The catalyst was characterized on X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, and differential thermal analysis/thermogravimetric analysis (DTA/TGA). The formation of the calcium oxi...

Heterogeneous catalyst was prepared from Portland cement. The heterogeneous tested for catalytic activity in the transesterification of non-edible, high free fatty acid feedstock, such as crude karanja oil (CKO), biodiesel production, at methanol reflux temperature. Gas chromatographic (Gc) analysis technique used to determine methyl ester yield. preparation low-cost sources, and use non-edible...

Crude and purified extracts of non edible seed.of Pongamia glabra ( Karanja) were tested for their toxicity growth and development against the 2 instar larvae of the American bollworm, Helicoverpa armigera (Hubner) a serious pest of cotton. Larvae reared on synthetic diet at concentrations of 1 and 0.5% of P. glabra exhibited 100% mortality, whereas at sublethal concentrations of 0.05% and 0.01...

The present work aims to study the Zooplankton seasonal distribution and diversity in Karanja reservoir, Bidar district for the period of two years from October 2001 to September 2003. We have recorded 36 species of which, 15 species belongs to rotifera, 11 species belongs to cladocera, nine species belongs to copepoda and ostracoda three species. Among zooplankton, particularly rotifera was th...

Production of biodiesel from edible vegetable oils using homogenous catalysts negatively impacts food availability and cost while generating significant amounts caustic wastewater during purification. Thus, there is an urgent need to utilize low-cost, non-food feedstocks for the production sustainable heterogeneous catalysis. The objective this study was synthesize a novel supported nano-magnet...

The increasing vehicular population leads to consumption of petroleum fuels at a faster rate. This problem results increase in the danger of petroleum fuels depletion and the remarkable increase in high crude oil prices. The increasing consumption of petroleum products has been a matter of great concern for the country for the financial growth as well as environmental pollution abatement. The s...
