“…Observed peaks at 1600, 1396 and 1150 cm −1 in all the samples are assigned to carbonate C-O stretching and bending vibrations [9], which is an indication of the presence of carbonate. The peak at 1396 cm −1 is very strong in both open-air burnt RPP and CRPPA ( Figure 2) and it is known for K 2 CO 3 [9,31,34,35]. Furthermore, the peaks located at 1005 cm −1 is ascribed to Si-O-Si asymmetric stretching vibration [34,36].…”

The present work was aimed at assessing the possible use of ripe plantain fruit peel as a green-base catalyst in synthesizing Azadirachta indica oil methyl esters (AIOME). The free fatty acid content of the oil (5.81 wt %) was initially reduced to 0.90 wt % using methanol: oil at 2.19 v/v, Fe 2 (SO 4 ) 3 at 6 wt %, time of 15 min and temperature of 65 • C. The pretreated oil was converted to AIOME in a transesterification process with calcined ripe plantain peel ash (CRPPA) at 700 • C as catalyst. The process was modeled by artificial neural network and optimized using genetic algorithm. The effectiveness of the developed CRPPA is ascribable to its high K content and microstructural transformation. The reliability of the model obtained was confirmed with a high coefficient of determination (R 2 ) of 0.996 and a low mean relative percentage deviation (MRPD) of 8.10%. The best operating variables combination for the process was methanol:oil of 0.73 v/v, CRPPA of 0.65 wt % and time of 57 min while the temperature was kept constant at 65 • C with a corresponding AIOME yield of 99.2 wt %. The results of this work demonstrated the potentials of ripe plantain peels and neem oil as cheap feedstocks for biodiesel production.

Abstract-Fe-Zn double-metal cyanide catalysts were synthesized by co-reaction of zinc chloride with potassium ferrocyanide in presence co-complexing agent and complexing agent. Acidity, basicity, morphology and textural characteristics of catalysts were studied using CO 2 -and NH 3 -temperature-programmed desorption (TPD), X-ray diffraction (XRD), scanning electron microscopy (SEM) and liquid N 2 -sorption data. Fe-Zn-1 catalyst with highest basicity was found to be more effective for transesterification of Jatropha oil with methanol to form biodiesel in a batch reactor. It was further used for optimizing the reaction condition such as effect of methanol/PC molar ratio and reaction time; and studying its reusability.Index Terms-Transesterification of Jatropha oil, Fe-Zn double metal cyanide, Biodiesel.

“…The production of wood ash is likely to increase in the future and finding effective applications for it is vital (2). Most of the proposed applications of wood ash thus far were in agriculture and forestry where it serves as a liming agent and increases the availability of nutrients in acid soils (2)(3)(4); as a component in concrete (5), cement, and mortar manufacturing (4,6,7); and as a catalyst for biodiesel synthesis (8).…”

Wood fly ash is an industrial by-product of the combustion of different wood materials and is mostly disposed of as waste on landfills. In our preliminary experiments, wood ash exhibited antibacterial activity against urban wastewater bacteria and we focused on wood fly ash as a potential substrate for wastewater disinfection. The addition of ash at a concentration of 10 g L -1 (1 %) caused an instant increase of pH in urban wastewater and landfill leachate. High pH (10.1-12.7) inactivated bacterial populations in the wastewater and the removal of faecal coliforms and intestinal enterococci after 6 h of contact was 100 % (below the detection limit; <1 CFU per mL) with the most efficient ash sample (ash from combustion of beech) both in urban wastewater and landfill leachate. Properly chosen wood fly ash, i.e. one that tends to increase the pH to the greatest extent, proved to be a very effective disinfection substrate. Considering that water treated with wood ash has a high pH and needs to be neutralised before discharge, ash would be suitable for disinfection of leachates when smaller volumes are treated.
