Methane reforming is a widely used method for hydrogen production, and catalysts play a crucial role in optimizing this process. This paper provides a comprehensive review of the catalytic aspects of methane reforming, highlighting significant progress and recent advancements. After reviewing various research works, it was seen that the conversion of methane and carbon dioxide is influenced by the specific surface area of catalysts. It is observed that the catalysts with larger surface areas exhibit higher methane conversion rates, although exceptions are observed in the case of perovskites, which demonstrate good conversion efficiency despite their smaller size. Cobalt (Co) and nickel (Ni) are commonly employed in catalysts for achieving higher conversion rates. Other than that, various rare-earth catalysts were also evaluated in the paper. To further optimize the production strategy, several crucial points are identified. These include a comprehensive understanding of the reaction mechanisms for catalyst design, the integration of in situ characterization techniques for studying catalyst changes and active species, collaboration between theoretical calculations and experimental studies, and the development of highly efficient and stable catalysts. Emphasis is placed on exploring cost-effective options, such as nickel and other non-noble metal catalysts, while assessing their performance at low temperatures and in advanced reforming systems. With the increasing importance of hydrogen and syngas production, upgraded reforming systems are expected to flourish soon.</p></div>","PeriodicalId":678,"journal":{"name":"Journal of Thermal Analysis and Calorimetry","volume":"149 24","pages":"14517 - 14534"},"PeriodicalIF":3.0,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142889873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dusty fluids are widely used in industries such as manufacturing and construction, particularly in areas like infrastructure development and material processing. They are used in petroleum transportation, gas purification, power plant piping, automotive exhaust systems, and sedimentation operations. In this study, dusty nanofluid is composed of copper nanoparticles suspended in a mixture of C<span>(_2)</span>H<span>(_6)</span>O<span>(_2)</span>-H<span>(_2)</span>O (50–50%) with a Prandtl number <span>(hbox {Pr}=3.97)</span>.

These ODEs are then solved numerically using MATLAB’s built-in \"bvp4c\" method. The effects of various involved parameters on velocity, temperature, skin friction, and Nusselt number are exemplified graphically. The findings indicate that increasing the nanoparticle radius causes temperatures to decrease for both phases, while increasing velocities for both phases. A rise in the suction parameter results in lower temperature and velocity for both phases. A surge in the Biot number significantly raises the temperatures of both phases. Increasing the suction parameter, nanoparticle radius, and Biot number increases the Nusselt number, which optimizes effective heat transfer efficiency by improving thermal conductivity and nanofluid mobility.

There are a total of thirty-seven input variables, being thirty-two regarding the geometrical parameters and five environmental/operating parameters. Surrogate-based optimization procedures (Kriging metamodel combined with Non-Dominated Sorting Genetic Algorithm, NSGA-II) are used to build the Pareto frontier for two objective functions: (i) maximization of both useful gain and thermal efficiency and (ii) maximization of useful gain and minimization of exergy destruction. The optimization results indicated that the useful gain of 8 inline PTC array can reach up to 1.0 MW for both thermal oils. By variation in the input parameters along with the PTC array, a broad range useful gain can be achieved, with negligible thermal efficiency degradation. With regard to the Pareto frontier of useful gain and exergy destruction, there is an important asymptotic point for useful gain, in which its augmentation just promotes the increase in exergy destruction. In terms of concentration ratio, the Pareto fronts showed that about 95% and 90% of PTC modules can be assumed at “heterogeneous” along with the array for the first and second objective functions, respectively.
