A key challenge in SCCM is determining the appropriate adjustments to blend parameters while anticipating their effect on coke oven health. Among these parameters, the stability of the coal cake plays a vital role in ensuring smooth oven operation and achieving high-quality coke production. Coal cake stability is strongly dependent on the crushing fineness of the coal blend and its moisture content. Excessive expansion of the coal cake can negatively impact oven health by increasing internal gas pressure, thereby accelerating structural deterioration. This study, conducted at Tata Steel, Jamshedpur, evaluates the influence of crushing fineness and blend moisture content on the vertical and lateral expansion behavior of the coal cake. Furthermore, the study examines how varying moisture levels affect the heating rate of the coal cake during the carbonization cycle at a crushing fineness level of 90%. The findings contribute to a better understanding of the interplay between blend preparation parameters and oven performance, supporting optimization of SCCM operations for improved coke quality and oven longevity.</p>","PeriodicalId":519,"journal":{"name":"Coke and Chemistry","volume":"68 11","pages":"965 - 971"},"PeriodicalIF":0.5,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147579357","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}

On adding 0.1 g of zinc ferrite to 50 mL of a phenol solution (concentration 1 g/L), the rate of destruction is doubled, with an ozone flux of 2.5 g/h. In the ozonolysis of circulating water, the initial colloidal structure of the sample breaks down. The characteristic destruction rate of phenolic compounds is found to be higher for circulating water than for an aqueous solution of phenol. The effective rate constant of phenol destruction in circulating water increases on adding zinc ferrite, but by a smaller amount than in an aqueous solution of phenol. That is associated with the need to oxidize the other organic compounds forming phenols in the initial stages. The proposed approach may be regarded as a promising means of reducing the energy consumption in ozonolysis and hence permitting the use of ozonolysis in decreasing the concentration of organic pollutants in the circulating water prior to biochemical treatment.</p>","PeriodicalId":519,"journal":{"name":"Coke and Chemistry","volume":"68 10","pages":"840 - 845"},"PeriodicalIF":0.5,"publicationDate":"2026-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147336401","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}

Moreover, the oxygen content of some gases varies significantly. Traditional single treatment methods have certain drawbacks and cannot achieve efficient and comprehensive treatment.

The low-oxygen VOCs produced by tanks with better sealing are led to the negative pressure pipeline of the gas for resource utilization as supplementary fuel; the high-oxygen VOCs produced by tanks with poorer sealing are led to the regenerative thermal oxidation (RTO) system for combustion treatment. After implementing this process in a coking enterprise with an annual output of 1.3 million tons, the comprehensive removal rate of VOCs was ≥98%, reducing carbon emissions by 3200 tons, and the stability of the system operation was significantly improved.
