Producing Effective and Clean Coke for Household Combustion Activities to Reduce Gaseous Pollutant Emissions

Table 6

Comparison of the surface area and porosity of the clean coke and the coke from the metallurgy samples.

Sample	Specific surface area (m^2/g)	Pore volume (cm^3/g)	Pore diameter (nm)
Clean coke	25.55	0.084	12.75
Coke	7.28	0.019	10.72
