Basic Decomposition For Sunflower Seed Peels And Study Of Carbonation Products And Their Effect On The Specifications Of The Prepared Carbon

Abstract

To investigate the optimal conditions for the basic decomposition of sunflower seed peels to produce a high-quality carbon precursor, and characterize the physical and chemical properties of the carbon precursor obtained from the decomposition process, one type of nut shell sunflower seed  peels was adopted which is characterized by extreme hardness and high lignin content to prepare an activated carbon. The quantity of iodine adsorbed by the experimental material surpassed that of the commercial model, especially at a 1:1 ratio. The experimental material achieved an iodine number of 907 and a methylene blue dye adsorption of 91- indicating superior performance and higher density. Additionally, increasing the proportion of the carbonated material from 0.5 to 2 significantly enhanced the number and property of internal pores, leading to improved adsorption properties .The experimental activated carbon exhibited superior performance compared to commercial models, particularly in terms of iodine number and methylene blue dye adsorption. While the increased KOH ratio led to a decrease in density, it also resulted in a highly effective activated carbon with neutral pH and low density. This suggests that the carbonization process effectively disrupted the original structure of the sunflower seed peels, creating a highly porous material.This study demonstrates that sunflower seed peels, combined with enhanced chemical processing, can produce highly efficient activated carbon. The results indicate significant potential for environmental and industrial applications. However, strategies to reduce moisture content and costs should be explored to maximize the benefits.
