Reduction of NOx and HC emissions in Waste Cooking oil Biodiesel using Nanoparticles of CsTPA
[摘要] Recyclable Nanoparticles of Cesium Tungstophosphoric acid (CsTPA) for reduced NOx emission in biodiesel using waste cooking oil of high acid value was investigated. The synthesized nano catalysts were characterized using FTIR, XRD, DLS, BET and SEM. The maximum yield of biodiesel reached 91% under optimized reaction conditions of 4% catalyst (w/w of oil), molar ratio of alcohol to oil of 10:1 for 4 hours at 65 °C. Engine performance and emission characteristics of fame acid methyl esters investigated in a four stroke diesel engine showed a decrease in the Brake Thermal efficiency and Mechanical efficiency with respect to diesel. The heteropolyacid successfully decreased the HC and NOx emissions in the biodiesel with an average reduction of 28 % and 10.3 % respectively. The nano catalyst also had excellent catalytic stability and reusability making it a promising catalyst for FAME production.
