The Use of Calcium Carbonate from Crushed Oyster Shells and Chicken Eggshells Mixed with Activated Charcoal for Hydrocarbon Particulate Filter

Abstract

INTRODUCTION

Air pollution is a perennial problem that keeps growing over the years. One of the main contributors to the high pollution level is the smoke coming from vehicles. In an attempt to decrease pollutants from vehicle exhaust pipes, the researchers investigated the use of crushed oyster shell, chicken eggshells, and activated charcoal as hydrocarbon particulate filter.

METHODS

Oyster shell and chicken eggshells were gathered, washed, pulverized, and set aside. Activated charcoal was bought. A filter that consisted of 100 g of oyster shells, 100 g of chicken eggshells, and 100 g of activated charcoal was prepared by encasing the oyster shells, chicken eggshell, and activated charcoal in a gauze pad and sealed using threads. The device was tested by getting the hydrocarbon and carbon monoxide values of the exhaust smoke before and after filtration.

RESULTS

Results show that the number of hydrocarbons present in the sample motorcycle before using the device was 43 PPmvol of hydrocarbon and 0.55 percent vol of carbon monoxide. After the filter was attached, the obtained data for hydrocarbons and carbon monoxide content was 16 PPmvol of hydrocarbons and 0.30 percent vol of carbon monoxide. In trial 2, 13 PPmvol of hydrocarbon and 0.28 percent vol of carbon monoxide. In trial 3, 12 PPmvol of hydrocarbon and 0.28 percent vol of carbon monoxide amount of carbon monoxide.

DISCUSSIONS

Results reveal that the hydrocarbon content of the smoke emission before and after the filter was used is 43.00 PPmvol and12.00 PPmvol, making a difference of 31.00 PPmvol. On the other hand, the carbon monoxide content of the smoke emission before and after the filter was used is0.55 percent and 0.28 percent, making a difference of 0.27 percent. This means that the hydrocarbon emission was reduced by 72.1percent, while the carbon monoxide was reduced by 49.1 percent.
