Abstract

One of the man-made problems of technological development is the processing and utilization of oil and agricultural wastes. In this study, the process of obtaining granular activated carbon from the agricultural rice waste was investigated. The granules were obtained using polyvinyl acetate, which binds rice residue and oil sludge. Carbonization and activation were carried out in a quartz glass tube inside of high-temperature vacuum furnace BR-12 NFT series. The length of the furnace is 300 mm, the diameter is 60 mm and the operating heating length is 200 mm. Carbonization was performed at a temperature of 500 °C, activation of carbonizate with water vapor in ratio 1:2 at a temperature of 850 °C. The effect of polyvinyl acetate, rice waste, oil sludge ratio on the product characteristics was analyzed, the most advantageous ratio for obtaining granular activated carbon was identified. The iodine adsorption activity of the granulated activated carbon, the total pore size, the mass fraction of moisture, the methylene blue adsorption activity and bulk density were determined. According to the results, the product obtained by using the rice husk, oil sludge and binder in a ratio by mass 9:1:1.1 corresponds to the DAK type of wood crushed activated carbon standard (GOST 6217-74).
