Pembuatan dan Karakterisasi Keramik Berpori yang Diaplikasikan sebagai Filter Emisi Gas Buang Pada Sepeda Motor Berbahan Bakar Premium

Abstract

Porous ceramic had been made based on kaolin, feldspar, activated carbon and volcanic fly ash of Mount Sinabung as aggregates by using dye pressing methods with aggregate’s varies from 0% to 20% of the total mass of the sample. Sample preparation was done by sieving stage 100 mesh material and mixing the ingredients for 15 minutes until homogeneous and utilized with an emphatic 5 tons and combustion temperature up to 1100OC and also held for 4 hours. Characteristics of porous ceramic which had been tested, those are mass shrinkage from 17.84 to 23.22%; combustion shrinkage from 0.98 to 16.46%; density 1.28 to 1.73 g/cm3 ; porosity from 35.27 to 40.88%; compressive strength from 1.69 to 1.92 MPa; hardness from 167.67 to 410.31 MPa; pore diameter 3-5 μm. The amount of gas emissions exhaust that is the absorption of CO from 19.67 to 69.47% ; the absorption of HC from 14.34 to 62.79% and the increasingof O2 from 2.77 to 26.14%; the increasingof CO223.91 to 58.58%. The amount of CO and HC gas absorptionand the increasing concentrations of O2 and CO2 indicate that filters had been madehas functioned as a catalyst converter.
