To promote the use of waste-originated resources in biodiesel production, this study proposes utilization leather tanning waste (LTW) and crab-shell (CS) as respective lipid source catalyst material. The obtained CS-based calcium oxide (CaO) has comparable textural properties with those existing waste-based catalysts shows high catalytic activity for conversion LTW to biodiesel. optimum yield f...

waste low density polyethylenes (ldpe) represent a source of energy and valuablechemicals, were pyrolysed catalytically in a batch reactor under atmospheric pressure. calciumcarbide was used as a catalyst to explore its effect on pyrolysis product distribution. the effect oftemperature, amount of catalyst and time on the yields of the pyrolysed products wasinvestigated. the effect of catalyst o...

In the world industries are growing very rapidly resulting in fast development. Various coming up such as that of dyes, paints, pharmaceuticals etc. Dyes used various and release pollutants environment. It is necessary to remove from Euphorbia neriifolia L. grow weed forests konkan region waste land area. This a typical latex bearing plant. can be converted into powder under sun drying process....

In this study, low quality oils (waste cooking oils) with high acid value (4.81 mg KOH/g) were utilized as the feedstocks for a transesterification reaction enhanced by additional microwave power and use of an NaOH catalyst. The kinetics under different times temperatures was studied. It found that in microwave-assisted reaction, optimum conditions 600 W follows: catalyst 0.8 wt %, 12:1 molar r...
