Using anthropogenic carbon dioxide (CO2) as a feedstock for the production of synthetic fuel has gained significant attention in recent years. Among various CO2 conversion pathways, natural gas via methanation holds promise because its potential both recycling and renewable energy storage. Nickel (Ni) ruthenium (Ru) are dominant metals employed catalysts reaction. This review summarizes research landscape Ni- Ru-based over last ten Bibliometric analysis revealed that China highest number publications, Chinese Academy Sciences is foremost academic institution, International Journal Hydrogen Energy leading journal this area research. The publication trend on Ni-based published at almost four times rate catalysts. Despite growth research, problems with catalyst stability kinetics still exist. latest catalytic systems, including supported, bimetallic, single-atom fundamental challenges associated process reviewed. provides new angle future studies based non-noble Ni noble Ru opens way additional area.

Though operation measures are utmost importance in industrial processes, they difficult to maintain when variable components dealt with. Four different scenarios based on various process phases compositions were experimentally evaluated. The results exhibited significant differences explosion pressure values, revealing most severe consequences during start-up phase, H2 is abundant, advanced (over 30 h operation), CO abundant composition. first case possessed 200 MPa/s change, while latter equal 152 MPa/s. These findings have provided guideline progressive applications with complex material mass balance.

This article considers modern approaches to obtaining synthetic oil from unconventional hydrocarbon feedstocks, including plastic waste, tires, biomass, coal, and extra-heavy oil. Particular attention is paid multi-stage technologies, such as pyrolysis, catalytic depolymerization, gasification followed by Fischer–Tropsch synthesis, hydrocracking of heavy residues. The important role catalysts in increasing the selectivity economic efficiency processes noted: nanostructured, bifunctional, pollution-resistant systems are increasingly used. Economic factors influencing competitiveness this industry considered, volatility prices for traditional oil, government support measures, development waste logistics infrastructure. It emphasized that strengthening position associated with growth environmental requirements stimulating recycling plastics, biomass; at same time, compliance high standards transparency emission control play a critical social aspects projects. In addition improving situation, contributes creation jobs, resolution problems shortage classical fields, increase energy security. concluded further improvement technologies integration into industrial clusters can turn sphere significant component future sector.
