Catalytic activity of materials prepared by means of sodium ion-exchange by potassium and cesium in NaY zeolite, was studied in the deoxygenation of methyl laurate, as biodiesel model compound. The increase of the Ion-exchange produced a basicity increase that leads to a lower deactivation in the deoxygenation of methyl laurate, reaching a steady conversion of about 92% for 4 h (time on stream, TOS) with the CsKY zeolite. However, the potassium ion exchange leaded to higher production of bio-hydrocarbons, especially unsaturated (96% of the C10, C11 and C12 production), with higher production of C11 by means of decarbonylation. Furthermore, mesoporosity on the KY zeolite was generated, using SDBS (sodium dodecylbenzene sulphonate) during the synthesis, with the aim of increasing its capacity to process bulky molecules. The presence of mesoporosity in the potassium zeolite allowed a higher tolerance to deactivation maintaining a steady conversion of about 90% for 4 h TOS. The yield to desirable products (C10 to C12 hydrocarbons) was about 37%. Therefore, biofuel upgrading can be carried out using potassium Y zeolite with mesoporosity.

在作为生物柴油模型化合物的月桂酸甲酯脱氧中，研究了通过钠离子交换在 NaY 沸石中通过钾和铯进行钠离子交换制备的材料的催化活性。离子交换的增加导致碱度增加，导致月桂酸甲酯脱氧的失活降低，使用 CsKY 沸石在 4 小时（运行时间，TOS）内达到约 92% 的稳定转化率。然而，钾离子交换导致更高的生物烃产量，尤其是不饱和烃（C10、C11 和 C12 产量的 96%），通过脱羰产生更高的 C11。此外，在合成过程中使用 SDBS（十二烷基苯磺酸钠）在 KY 沸石上产生了介孔性，目的是提高其处理大分子的能力。钾沸石中介孔的存在允许更高的失活耐受性，在 4 小时 TOS 内保持约 90% 的稳定转化率。所需产物（C10至C12烃）的产率为约37%。因此，可以使用具有介孔性的钾 Y 沸石进行生物燃料升级。
