The preparation of such water–coal fuel from Kuznetsk Basin coal of different ranks and with different ash content is studied experimentally. The possibility of obtaining a composite fuel using fuel oil and methyl alcohol is investigated. The method is refined and the parameters of deep coal enrichment by means of oil granulation are determined. Coal–oil granulates of ash content ≤5.5% are obtained, and the possibility of preparing highly reactive water–coal fuel on that basis by the proposed technological process is considered. The highly reactive water–coal fuel is prepared by wet crushing of coal in a vibrational mill, with treatment of the suspension obtained in a rotary–pulsational cavitation system. The structural, rheological, and thermophysical properties of the highly reactive water–coal fuel are investigated.

The sorbent is produced from D coal by alkaline activation at 800°C with 1 h holding, when the coal/KOH mass ratio is 1.0. This sorbent is microporous, with a high specific surface (1340 m2/g). The sorbent is modified by steeping with ammonium bromide solution of different concentrations (1, 2, and 4%). Such modification changes all the textural characteristics of the sorbent. The specific surface SBET and total pore volume VΣ decrease. Thermogravimetric analysis establishes the temperature limits on oxidative pyrolysis of the sorbent samples: the ignition temperature and complete combustion temperature. Taking account of the time parameters, the ignition and combustion indices are calculated. It is found that increase in concentration of the ammonium bromide solution is accompanied by increase in the ignition temperature Tig of the samples and also the temperature T1 at which mass loss begins. In addition, the ignition index D and combustion index S increase. The results show that modification of the sorbents with ammonium bromide raises the threshold of oxidative pyrolysis.</div>","PeriodicalId":519,"journal":{"name":"Coke and Chemistry","volume":"66 9","pages":"480 - 484"},"PeriodicalIF":0.4,"publicationDate":"2023-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139051903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In studying the influence of the modifier consumption on the effectiveness and selectivity of coal flotation, the collector employed is an oil-refining byproduct: Motoalkilat (MTA). The frothing agent is KOBS, which is the still residue from the production of butyl alcohol. The acetylene reagent DK-80 is also employed as a collector. By using DK-80 reagent and the modifier Sinterol in the flotation of coal with different mineral content, the physicochemical properties of the coal surface may be altered and the flotation process may be improved. This combination reduces the consumption of the main reagents and tends to increase the extraction of combustible mass in the concentrate and to reduce the losses of organic mass with the flotation wastes.

It is devoted to the use of electron paramagnetic resonance (EPR), nuclear magnetic resonance (NMR), and infrared (IR) spectroscopy to determine the structural and molecular composition of Berezovsky and Kaichaksky-1 lignite and also D coal, in selecting the optimal coal for sorbent production. Comparison of the IR and NMR results indicates that the aliphatic side chains in the selected coal samples are shorter than those in other Siberian coal samples. Comparison of NMR and EPR data shows that, compared to Berezovsky lignite, Kaichaksky-1 lignite has a higher content of oxygen-bearing groups. Its paramagnetism is due to the presence of aroxyl radicals of semiquinone and phenoxyl type. EPR spectroscopy indicates that Kaichaksky-1 lignite has the highest content of paramagnetic complexes based on Fe3+. That may affect the quality of the sorbents produced.","PeriodicalId":519,"journal":{"name":"Coke and Chemistry","volume":"66 9","pages":"443 - 448"},"PeriodicalIF":0.4,"publicationDate":"2023-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139054268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
