Abstract A novel carbon solid acid catalyst was prepared by incomplete hydrothermal carbonization of β‐cyclodextrin into small polycyclic aromatic sheets, followed the introduction –SO 3 H groups via sulfonation with sulfuric acid. The physical and chemical properties were characterized in detail. simultaneously catalyzed esterification transesterification reactions to produce biodiesel from high free fatty (FFA) containing oils (55.2 %). For as‐prepared catalyst, 90.82 % oleic esterified after 8 h, while total yield FFA reached 79.98 12 h. By contrast, obtained showed comparable activity biomass (such as sugar, starch, etc.)‐based Amberlyst‐15 resulted significantly lower levels conversion, demonstrating its relatively catalytic for simultaneous transesterification. Moreover, can be regenerated, it has potential use production a content.
