Lignosulfonate was added to the mixture to produce briquetted activated carbon by processing rice residue<br>(husk and straw) and oil sludge together. The mixture was carbonized and activated in a BR-12 NFT series hightemperature vacuum tube furnace with a length of 300 mm and a diameter of 60 mm and a heating section length of<br>200 mm in a quartz glass tube. Briquettes obtained by adding rice waste (husks and straw), oil sludge and<br>lignosulfonate were placed in the kiln. Carbonation was carried out at a temperature of 500°C, activation was carried<br>out at a temperature of 850°C in a ratio of 2: 1 with water vapor. The effect of the relationship of the addition of<br>lignosulfonate binder to rice residue and oil sludge on the product properties was studied. The optimal ratio of cotreatment of the mixture was found in the ratio of rice residue: oil sludge: lignosulfonate = 9: 1: 2 (by weight). The<br>adsorption activity of the obtained product on iodine, the total volume of pores on water, the mass fraction of<br>moisture, the adsorption activity on methylene blue and the bulk density were studied. Activated carbon obtained<br>from both rice straw and rice husk has high sorption properties. According to the results of experimental studies,<br>activated carbon obtained by adding lignosulfonate to rice straw and oil sludge in a ratio of 9: 1: 2 corresponds to the<br>brands BAС-A, WAC, BAC-Au</p> ER -
