Experimental analysis on development of algae based catalytic convertor for ecofriendly environment

Due to increased use of automobiles in some of the major cities had resulted in serious concerns about urban air quality caused by engine exhaust gas emissions and also more harmful species derived from them via photochemical reactions. The three main exhaust gas pollutants derived from exhaust emissions are hydrocarbons, carbon monoxide and nitrogen oxides. Engine modifications are not alone sufficient to control them therefore the catalytic systems are introduced to do this. But the biggest limitation of regular catalytic convertor is the use of precious metals like platinum, titanium, palladium etc. in this article an algae based catalytic convertor is fabricated and experimentally tested. The conducted analysis and experiments shows that algae based catalytic convertor is indeed a best substitute to the regular catalytic convertor. The CO2 emission was reduced from 0.9 vol % to 0.2 vol % and the CO emission was reduced from 14.22 vol % to 0.68 vol%.
