技術說明

此技術主要以價格低廉的天然矽藻土，以水熱合成法和氫氧化鈉及氧化鋁反應，製造低成本的鈣霞石型沸石觸媒（Cancrinite-type Zeolite），並應用在催化三酸甘油酯轉酯化反應以生產生質柴油。此技術中水熱合成法的反應條件相對其他文獻中的條件而言，具有反應溫度低、及反應時間短的優勢。如果三酸甘油酯來源自像是大豆油、棕櫚油的植物油，反應於甲醇中進行，此鈣霞石型沸石觸媒催化轉酯化反應的效率，在反應2小時、反應溫度63C下，可以達到95%。 A high conversion efficiency (circa 95%) of triglycerides to biodiesel was successfully attained via heterogeneous catalytic transesterification of triglycerides in short-chained alcohols using the cancrinite-type zeolite fabricated from natural diatomite. Briefly, the cancrinite-type zeolite was prepared from a hydrothermal reaction of natural diatomite with an aqueous solution of sodium hydroxide and aluminum oxide. The advantage of this invention on the hydrothermal synthesis of the cancrinite-type zeolite includes relatively lower reaction temperature and shorter duration of hydrothermal reaction. Practically, the conversion efficiency near 95% of soybean oil and palm oil to biodiesel could be achieved at 63C with 2 hours.
