In this article, the effect of gelatin as a binder to obtain granular activated carbon by joint processing of rice waste (husk and straw) and oil sludge was studied. Carbonation and activation of the granules were carried out in a high-temperature vacuum tube furnace of the BR-12 NFT series with a length of 200 mm, in a heating tube made of quartz glass with a length of 300 mm and a diameter of 60 mm. Carbonation was carried out at a temperature of 500°C, activation-by water vapor at a temperature of 850°C, at a ratio of water and carbonizate 2:1. The effect of the ratio of gelatin binder, rice waste and oil sludge on the properties of the activated carbon was studied. The optimal ratio of the joint processing of the mixture is rice husk: oil sludge: gelatin = 9:1:2 (by weight). The studies were carried out according to the following indicators: adsorption activity for iodine, total pore volume for water, mass fraction of moisture, adsorption activity for methylene blue, and bulk density. Granulated activated carbon corresponds to the BAU-MF brand.
