Abstract:
1. A method for removing one or more volatile organic compounds from a gas stream, comprising passing the gas stream through a dynamic continuous gas flow treatment system comprising an adsorption column packed with a bed consisting of 1-6 cm of a granular activated carbon obtained from date palm pits with an average particle size of 1.0 to 1.2 mm, wherein the granular activated carbon is obtained by a process comprising: cutting the date palm pits into particles; mixing the particles with an acid solution to form soaked date palm pits; removing gas and vapor from the soaked date palm pit particles in stainless steel tubes; heating the tubes containing the date palm pit particles inside a muffle furnace; transferring the tubes containing the date palm pit particles to a desiccator and cooling; washing the desiccated and cooled granular activated carbon with water and drying; and sieving the washed and cooled granular activated carbon.
