Outline
In order to clarify the research hotspots, development trends and accident risk characteristics of alcohol-based fuels, and point out the direction for the development of alcohol-based fuels, CiteSpace software was used to collect 3 951 relevant journal papers from 1978 to 2024 in China National Knowledge Infrastructure. Bibliometrics and knowledge map visualization analysis methods were used to systematically analyze the annual publication volume and subject distribution in this field, and analyze research hotspots from keyword co-occurrence, clustering and emergence. The results show that the research on alcohol-based fuels in China has experienced three stages of continuous growth, fluctuation adjustment and steady development. At present, driven by the development of national energy strategy and technology, the research attention has been steadily improved. The research involves many fields such as electric power, chemical industry, automobile, power and fuel. The research hotspots are highly concentrated in the four major themes of methanol fuel preparation technology, fuel cell application, power and environmental impact assessment of methanol fuel. Existing research significantly focuses on basic material properties and technology applications, and systematic research on safety risks is relatively scarce. Therefore, this paper further clarifies the bottleneck of current risk prevention and control, and puts forward that future research should focus on fuel intrinsic safety technology, construction of intelligent supervision system of the whole chain and improvement of emergency response capacity, so as to provide theoretical reference and direction for the safe development of alcohol-based fuel.
