Preparation of Activated Carbons from Waste Coffee Beans

Preparation, characterization and phenol adsorption capacity of activated carbons from African beech wood sawdust

In the present study, different activated carbons were prepared from carbonized African beech wood sawdust by potassium hydroxide activation. The activated carbons were characterized by brunauer–emmett–teller, scanning electron microscope, fourier transform infrared spectroscopy, and thermogravimetric analyzer. The phenol adsorption capacity of the prepared carbons was evaluated. The d...

Surface Area Determination of Activated Carbons Produced from Waste Tires Using Adsorption from Solution

The following study demonstrates the possibility of producing different activated carbons from a mixture of waste tires and tubes. The mixture was pyrolyzed at different temperatures namely (400,450 and 500 о C) for two hours for the determination of best condition of heating. It was found through the study that semi carbonized marital produced via pyrolyis at 500 о C was the best; thus it was ...

Adsorption of acid dye onto activated carbons prepared from agricultural waste bagasse by ZnCl2 activation.

A series of activated carbons were prepared from agricultural waste sugarcane bagasse by chemical activation with zinc chloride (ZnCl2) as an activating agent at 500 degrees C and 0.5 h soaking time. The Langmuir surface area and total pore volume were used to estimate the average pore diameter of the carbon products. The values of the surface area and pore volume increased linearly with increa...
