چکیده
|
The single step procedure for the synthesis of micro porous activated carbon (ac) from saudi date tree fronds using mixture of gases (n2 and co2) at different carbonization/activation temperatures staring from 800°c to 1000°c and a ramp rate of 10 degree per minute,using alloy 330 horizontal reactor for tube furnace is studied. flow rate of both gases are kept at 100ml/min. the surface areas of the ac prepared at 800,900 and 1000°c after 15 minutes activation time are 194,487 and 620 m2/g,respectively. scanning electron microscopy for surface morphology,fourier transform infrared spectroscopy for functional groups and elemental composition of carbon,hydrogen,nitrogen (wt %) are also carried out that also verifies the same trend. moreover by increasing the activation temp the yield decreases from 23% to 20%.
