description |
For decades, the inclusion of activated carbon (AC) adsorption technique through
filtration has gained significant interest on improvement of indoor air quality (IAQ)
by reducing level of pollutant. The interest of reseachers in palm shell AC (PSAC)
keep increase owing to the fact that this material has superior characteristic as
compared to commercial AC. However, the investigation of PSAC performance for
air filtration are still limited and no research could be found on relating the effect of
burner for carbonization on PSAC properties. Therefore, the current research was
focused on producing PSAC by using new fabricated burner, exploring the effect of
combination of physical and chemical activation towards PSAC properties and
investigating of PSAC air filter performance used in Mechanical Ventilation Air
Conditioning (MVAC) system. Preliminary studies began with IAQ monitoring in
different building condition. The present data revealed that at certain situation, the
buildings environment was below than satisfactory level and required mitigation plan
by introducing new air filtration media in MVAC system. The best quality of charcoal
was obtained by Horizontal burner with less fume formation during carbonization
process compare to other design. The physical properties analysis of palm shell
charcoal showed the carbonization time (CT) 2 hours gained better charcoal properties
and highly recommended to continue into the activation process. After the activation
process, PSAC physical+chemical shows significantly higher pore development,
surface area and adsorption capacity compare to the other process. The lowest density
and the highest porosity up to 0.4632 g/cm
and 7.11% was calculated while the
highest Iodine number of 1091.05 mg/g and BET surface area of 713.7 m
3
/g was
obtained respectively in PSAC physical+chemical. Meanwhile, microstructure and
composition analysis shows that, PSAC physical+chemical fully produced honeycomb
form of porosity and comprised of C, O, K and Ca contents for high adsorption
capacity. The improvement of IAQ in the buildings was achieved with the application
of PSAC air filter which shows low concentration of CO2 with 302 ppm, CO with 0.4
ppm , TVOC with 0.1 ppm and PM10 with 0.02mg/m

respectively compare to the
