“…Petroleum was used as a binder to obtain activated carbon from hard coal. Coal and oil slag are ground together, 4-5% KOH solution is added and activated carbon up to 40-50% by weight is obtained, which allows to remove N, N-dimethylformamide from industrial wastes [30][31][32]. In addition, technical lignosulfonate dried in air until dry was used as a binder when using peat as a carbon material [33][34][35].…”

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

Relevance. The relevance of the scientific subject is based on the search and solution of psychological and pedagogical problems of the methodology of computerization of gaming technologies in teaching chemistry. The process of committing experimental verification of the methodology of computerization of gaming technologies in teaching chemistry. Purpose. The purpose of the article is to study the process of using computer gaming technologies in the educational process of a higher educational institution during chemistry classes. Methodology. Such methods as analysis, synthesis, comparison, generalization of views belonging to Kazakh and European researchers in scientific and educational literature on the issue of researching methodology of teaching chemistry and technology of computerization of gaming technologies, graphic ones – for visual illustration and comparison of results obtained during research, are at the core of the methodological approach of research. Results. The training course on the topic “Features of creating and using a STEAM-oriented educational environment of the higher education”, a special course for students in the Abai Kazakh National Pedagogical University on the topic “Technologies of the development of computer games”, are developed and implemented, the development of and the application for an international grant project aimed at improving investment of the implementation of gaming technologies in educational process oriented at learning chemistry are accomplished and proposed respectively. Conclusions. The promising directions of improvements in the methodology of computerization of gaming technologies in teaching chemistry are formed. The practical value of the work is to determine the psychological and pedagogical problems of the methodology of computerization of gaming technologies in the process of teaching chemistry, namely: the development of a STEAM-oriented educational environment, the content of computerization of gaming technologies, the improvement of investment in the implementation of gaming technologies in the educational process of learning chemistry.
