Abstract

Banana stem midrib has potential as glucose source through catalytic hydrolysis assisted by ultrasonic (sono-hydrolysis). Besides, natural sand-based silica is potential as raw material for zeolite synthesis. The purpose of the study was to do two things: i) characterize HY-zeolite made from natural sand-based silica and ii) determine whether or not HY-zeolite is effective for sono-hydrolysis of banana stem midrib. There was a total of four processes that were carried out, including i) the extraction of silica, ii) the synthesis of HY zeolite, iii) the hydrolysis process, and iv) the glucose content test. The results of the study were gain two things: i) The findings of X-ray florescence (XRF), X-ray diffraction (XRD), scanning electron microscopy (SEM), and fourier transform infrared (FTIR) on HY-zeolite are 2.3 Si/Al, obtained 2 theta and d-spacing data similarities for HY-zeolite, and formed T-O-T, O-T-O (T = Si/Al), and Si-OH groups respectively; and ii) HY-zeolite with ultrasonic was effective for hydrolyzing cellulose into glucose at maximum temperature and time, 55 °C and 6 hours.
以天然砂基二氧化硅hy -沸石为催化剂对香蕉茎中脉进行声波水解
通过超声催化水解,香蕉茎中脉具有作为葡萄糖源的潜力。此外,天然砂基二氧化硅有潜力作为合成沸石的原料。本研究的目的是做两件事:1)表征由天然砂基二氧化硅制成的hy -沸石;2)确定hy -沸石对香蕉茎中脉的超声水解是否有效。共进行了四个过程,包括i)二氧化硅的提取,ii) HY沸石的合成,iii)水解过程,iv)葡萄糖含量测试。研究结果有两点:i) hy -沸石的x射线荧光(XRF)、x射线衍射(XRD)、扫描电镜(SEM)和傅里叶变换红外(FTIR)结果为2.3 Si/Al,得到了hy -沸石的2个θ和d间距数据相似性,分别形成了T- o -T、O-T-O (T = Si/Al)和Si- oh基团;超声波hy -沸石在最高温度和时间(55℃,6 h)下水解纤维素为葡萄糖效果最好。
