SEM and TEM results show that the CeO<sub>2</sub>-ZrO<sub>2</sub> nanocrystal particles gradually aggregate with the extension of hydrothermal processing time. A moderate hydrothermal processing time can facilitate the engineering of catalyst morphology at micronmeter scale, however, excessive hydrothermal synthesis time would contrarily destroy the micrometer scaled catalyst morphological structure. The result of XPS, O<sub>2</sub>-TPD and H<sub>2</sub>-TPR analysis indicates that the hydrothermal synthesis process is conducive to generating lattice defects (oxygen vacancies) of CeO<sub>2</sub>-ZrO<sub>2</sub> solid solution. This is a key factor for enhancing the concentration of surface-active oxygen species. The CeO<sub>2</sub>-ZrO<sub>2</sub> catalyst prepared by 48 h of hydrothermal processing time (CZ-48 h) exhibits the highest concentration of surface-active oxygen species and oxygen vacancies. Interestingly, the CeO<sub>2</sub>-ZrO<sub>2</sub> catalyst synthesized by 6 h of hydrothermal processing time (CZ-6 h) exhibits oxygen vacancy and surface-active oxygen levels that are close to the CZ-48 h, which is obviously more than the traditional co-precipitation CeO<sub>2</sub>-ZrO<sub>2</sub> catalyst (CZ-0 h). The soot catalytic elimination performance of the CZ-6 h is also significantly superior to that of the CZ-0 h catalyst. Therefore, this study suggests that the short-time hydrothermal processing is an effective and low-cost strategy to create more oxygen vacancies and improve catalytic performance of CeO<sub>2</sub>-ZrO<sub>2</sub> solid solution.</div></div>","PeriodicalId":326,"journal":{"name":"Fuel Processing Technology","volume":"276 ","pages":"Article 108294"},"PeriodicalIF":7.2,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144686155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the radial distance from the center line extends, the occurrence of hydrocarbons is mainly dominated by lean combustion reactions. This trend is consistent across all oxygen concentrations in the oxidizer stream during oxy-fuel combustion. At greater distances from the burner plane, the air case and the oxy-fuel condition with 33% oxygen concentration show the highest similarities in the concentrations of unburned hydrocarbons.

Its combustion performance is comprehensively evaluated using coke oven gas as the fuel in a fixed-bed reactor. The results show that the selection of an appropriate reaction temperature significantly influences the performance of the oxygen carriers. The CH<sub>4</sub> conversion of CuFe20M and CuFe20C reaches the maximum of 95.90 % and 96.72 % at 900 °C, respectively. The CO conversion is not sensitive to temperature change. Excessively high reaction temperatures (>900 °C) lead to a noticeable increase in carbon deposition, resulting in a decline in carbon capture efficiency. Increasing the fuel gas flow rate will suppress the carbon deposition and improve the carbon capture efficiency. Correspondingly, shortening the reaction time will lead to the decrease of CO<sub>2</sub> yield. Long-period CLC tests of COG reveal that the hydroforming-derived CuFe20C oxygen carrier exhibits excellent stability and reactivity compared to the extrusion-spheronization-derived CuFe20M oxygen carrier.

However, previous studies suggest limited high-temperature potential of native starch in water-based drilling fluids (WBDFs), mainly due to insufficient research on amylose-to-amylopectin ratios. This study investigates the hydrothermal stability and filtration control performance of corn starches with different amylose-to-amylopectin ratios in WBDFs to address this issue. The results demonstrate that amylopectin content significantly influences the hydrothermal stability and filtration control performance of WBDFs. Waxy corn starch, with 100 % amylopectin content, exhibits excellent performance, achieving a filtration loss of only 7.2 mL even at 160 °C. In contrast, as the amylopectin content decreases, the temperature resistance of normal corn starch declines below 140 °C, while high-amylose corn starch shows poor filtration control even at 120 °C. The key factor contributing to these differences is the amylopectin content. The “clustered or chrysanthemum-like” structure and multi-branched chains of amylopectin enhance bentonite interactions, improving colloidal stability and particle distribution. Slower degradation of amylopectin also boosts hydrothermal stability and dense mud cake formation.
