The main aim of this work was to develop a sustainable Ni/Zeolite catalyst derived from geothermal solid waste for waste cooking oil processing. The effects of catalyst concentration and operation temperature on the transesterification process for biodiesel production which used waste cooking oil as feedstock were investigated to determine the optimum biodiesel process condition. Results have shown the synthesized Ni/Zeolite catalyst was granular in shape and crystalline with increased surface area and pore volume, 80.661 m g, and 0.123 cc g respectively. Meanwhile, the highest biodiesel yield obtained was 89.4 % at 3 % w/w Ni/Zeolite catalyst addition and 60 °C operating temperature. The reusability of the synthesized catalyst was also investigated, with results showing the biodiesel yield decreasing to 73.3 % after three cycles.
本工作的主要目的是开发一种可持续的镍/沸石催化剂，源自地热能固体废料，用于处理废弃食用油。考察了催化剂浓度和操作温度对以废弃食用油为原料的生物柴油生产中酯交换过程的影响，以确定最佳的生物柴油工艺条件。结果表明，合成的 Ni/沸石催化剂呈颗粒状，结晶度增加，比表面积和孔体积分别为 80.661 m²/g 和 0.123 cc/g。同时，在 3%w/w 的 Ni/沸石催化剂添加量和 60°C 的操作温度下，获得的最高生物柴油产率为 89.4%。还研究了合成催化剂的可重复使用性，结果表明，三次循环后生物柴油产率下降至 73.3%。
