A new design (Digital Baffle Fenton-Solar Batch Reactor (DBFSBR)) has been invented to enhance from removal process. Cost–active oxidation is unique to the hot subjects in the remediation of environmental contaminants in current years. Organic policonsumption is known by way of well-organized activators in initiating some advanced oxidation processes toward producing free radicals. Subsequently, numerous source wastewater comprises certain quantities of organic compounds, and solar Fenton oxidation (SFO) homogeneously originated through organic pollutants would consume request potential in numerous belongings of contaminated water remediation. This might remain done utilizing SFO toward minimalizing the organic in produced water (PW). To enhance the purification of pollutant water by heavy metal, an original method of the squalor of the organic metal was emphasized. In the work was originated that the organic elimination remained touched 97.25% at 100 ppm hydrogen peroxide, 20 ppm ferrous sulfate pH 6.5, metal concentration, and 150 min solar time. The aptitude of Fenton’s reagent to eliminate organic compounds was amplified after the addition of different concentration agents.

On March 4, 1931, by decree of the Presidium of the Supreme Economic Council of the USSR, the Coal Chemical Institute of the Urals (UUKhIN) was established on the basis of the coal chemical laboratory at Ural Chemical Research Institute (UNIKhIM). The first director was N.N. Rogatkin. In the 1930s, with a view to developing a resource base for the Soviet coke industry, the Institute’s staff began investigating the suitability of coal from the Karaganda, Kizelovsky, and Pechora Basins and also fields in Eastern Siberia, the Baikal region, and Central Asia. Many technologies for coal processing and the production of coke and chemical byproducts have been developed at VUKhIN. Biochemical wastewater treatment technology developed by VUKhIN has been introduced at enterprises in the former Soviet Union, Iran, and Turkey. VUKhIN has assisted in modernizing coal enrichment facilities for the coke industry. For the first time anywhere, selective crushing of coal with pneumatic separation in a fluidized bed has been put into practice. A method of ammonium sulfate production without the need for a saturator has been developed. Venturi scrubbers have been introduced. A scientific school of applied coal petrography has been founded. A theory of coking and has been developed, along with the scientific principles for industrial methods of coal preparation and coking. New technologies have been developed for coke production from poorly caking coal and for the production of special types of coke. Today, VUKhIN is the only Russian institute devoted to research, design, standardization, and development in coke production.","PeriodicalId":519,"journal":{"name":"Coke and Chemistry","volume":"69 3","pages":"101 - 104"},"PeriodicalIF":0.6,"publicationDate":"2026-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148285404","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}

The optimal agglomeration method is usually pelletization, especially for sources that are far from steel mills. The induration of pellets permits their desulfurization by the transfer of sulfur to the gas phase (as SO2 and SO3), with subsequent capture of harmful components in the gas treatment department. In this technology, heating of the pellets by means of synthetic gas (syngas) derived from coal is of interest. The proposition considered in the present work is that the use of syngas instead of natural gas impairs pellet desulfurization. With a moderate sulfur content in the unfluxed material (no more than 0.3%), no significant difference in the desulfurization when using syngas and natural gas is seen, even though the gas entering the pellet bed contains 1–2% less oxygen (since the consumption and excess of air are lower). However, with a higher sulfur content in the initial material, the use of syngas rather than natural gas results in greater residual sulfur content in the final pellets. The use of syngas when the sulfur content in the ore is 0.5% leads to increase in the pellet’s sulfur content by 0.0028% and on fluxing by 0.0026% (in absolute terms). With decrease in productivity and increase in desulfurization time, the residual sulfur content in the pellets declines. However, in this case, heating by natural gas reduces the pellets’ sulfur content relative to syngas by 0.0048% and 0.0168% (again in absolute terms) for fluxed pellets. In terms of heat consumption, the use of syngas offers a small benefit: a relative decrease in unit heat consumption by 12 ± 3%. That is associated with the smaller air volume employed.","PeriodicalId":519,"journal":{"name":"Coke and Chemistry","volume":"69 2","pages":"49 - 55"},"PeriodicalIF":0.5,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148060744","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 turn, valuable constituents of wax include saturated hydrocarbons, aliphatic saturated acids and alcohols, complex esters of carboxylic acids, azulene, and sterols. Some of its components are biologically active. In the present work, fractions rich in biologically active components are derived. By saponification, wax from Tyulgan lignite is divided into saponifiable and nonsaponifiable components. By the synthesis of inclusion compounds with urea, each component is divided into three fractions. The first is obtained at room temperature, while the second is obtained on cooling to +4°C. The third consists of molecules that do not form adducts with urea. In addition, both components of the wax are treated with different initial concentrations of the reaction mass. It is found that reaction of the wax components with urea solution concentrates the biologically active minor constituents. These constituents may be concentrated by a factor of 1.20–17.77; in particular, the factor is 11.07 for hexacosanoic acid and 17.77 for tetracosanoic acid. It is also found that saturated fatty acids with a urea/sample ratio greater than 4 : 1 tend not to form inclusion compounds. This trend grows weaker with elongation of the aliphatic fragment of the guest molecule.","PeriodicalId":519,"journal":{"name":"Coke and Chemistry","volume":"69 2","pages":"70 - 77"},"PeriodicalIF":0.5,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148060743","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}
