This research mainly compares several aspects of rapeseed oil as a raw material for biodiesel. This includes its physical and chemical properties, production process, fuel performance, environmental impact and industrial applications. Different catalysts, process parameters and conversion methods were compared in the study. It was found that when rapeseed oil was used to make biodiesel, the yield was good and the fuel performance was also excellent. For instance, the cetane number, calorific value and low-temperature fluidity can all meet the standards. The emission performance also complies with international fuel requirements. Rapeseed oil biodiesel is of great significance in reducing greenhouse gas emissions and achieving renewable energy goals. However, many problems were also encountered during the promotion process. For instance, high raw material costs, conflicts in land use, competition with food applications, and how to make high-value use of by-products. Current new research is paying more attention to green catalysts, enzymatic processes, the reuse of by-product glycerol, and the integration with the circular bioeconomy. In the future, genetic breeding, process integration and policy support may further enhance the sustainability and market competitiveness of this biodiesel. The purpose of this research is to provide references and directions for energy policies, industrial development and subsequent scientific research.
