Synthesis of Activated Carbon from Saudi Date Tree Fronds by Gaseous Mixture (N-2 and CO2)

摘要

The single step procedure for the synthesis of micro porous activated carbon (AC) from Saudi date tree fronds using mixture of gases (N-2 and CO2) at different carbonization/activation temperatures staring from 800 degrees C to 1000 degrees 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 degrees C after 15 minutes activation time are 194, 487 and 620 m(2)/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%.
