A novel method of preparing activated carbons from oil-palm-stone chars by microwave-induced CO 2 reaction was studied in this paper. The effects of processing parameters (gas flow rate, input microwave power and exposure time to microwave energy) and the presence of CuO receptors on the characteristics of the activated carbons were investigated in order to determine and optimise the control...
The feasibility of preparing activated carbons from oil palm stones by one-step CO 2 activation was studied. These oil palm stones are major solid wastes generated from palm-oil processing mills. Experimental results showed that the particle size of the starting material and heating rate appeared to have no significant effects on the BET surface areas of the activated carbons but CO 2...
The feasibility of preparing activated carbons from extracted oil palm fibre, an abundant oil palm waste, was studied. Preliminary tests were conducted to investigate the influences of different operating parameters, such as initial material size, inert gas flow rate, heating rate, pyrolysis temperature and hold time, on the properties of the pyrolysed chars. The pyrolysed chars were characterized...
