Study on obtaining high performance diesel/biodiesel fuel by using heterogeneous catalysts

摘要

The purpose of our work was to produce high quality diesel/biodiesel and to meet the biodegradability requirement by using renewable raw materials. The technological process using heterogeneous catalysts is more environmentally friendly than the conventional approach for the preparation of alkyl esters. The heterogeneous catalyst was prepared by co-precipitation and subsequent calcination and BET, XRD, FT-IR and SEM techniques were employed in order to describe the structural and morphological characteristics. The results indicated that the prepared catalysts possessed high activities and stabilities during the catalysis process. The performance of the obtained esters was evaluated by HFRR and cloud/pour point tests. Research suggested that these synthesized esters have an improved effect on the lubricating property and cold flow performance of diesel fuels.
