Preparation of Carbon Sorbents from Certain Types of Biomass

An integrated study of olive pits and walnut shells as raw materials for conversion into carbon sorbents was performed. The results of thermogravimetric studies and proximate and ultimate analyses of the raw materials allowed us to choose a processing technique and the performance characteristics of carbonization. The sorbents based on the test plant waste materials were found to exhibit high strength and well-developed pore structure with a high specific surface area of micropores and sufficiently developed mesoporosity. These sorbents were superior to high-quality active carbons in terms of adsorption capacity for substances with various molecular sizes.
