Reduction of Carbon Dioxide Emission from Diesel Engine Fuelled with Plastic Pyrolytic Oil Using Modified Charcoals

Abstract

Abstract Carbon dioxide is one of the greenhouse gases majorly contributing to the global warming and greenhouse effects. Combustion of fossil fuels such as coal, petroleum products and natural gas for power production, transportation and industrial applications produce maximum amount of carbon dioxide. Hence, reduction of CO2 emission is mandated to avoid additional add on to the atmosphere and control global warming. A new low cost carbon trapper using modified charcoals has been designed and tested in a stationary diesel engine for the reduction of carbon dioxide emission and results were reported in this article. Normal wooden charcoal was produced and impregnated with NaOH and KOH. These two modified charcoals, Normal wooden charcoal and commercially purchased activated charcoal were testes individually and compared with each other. Also the effect of amount of different charcoals at 100 grams, 200 grams and 300 grams on carbon dioxide reduction were also tested. The potassium hydroxide (KOH) impregnated wooden charcoal with 300 grams mass shows the best result of 63.92% CO2 reduction at 75% engine load and sodium hydroxide (NaOH) impregnated charcoal shows 62.89% reduction in CO2 at the same engine load due to increased adsorption along with absorption and high porosity.
