Sono-hydrolysis of banana stem midrib using HY-zeolite from natural sand-based silica as a catalyst

<span>Banana stem midrib has potential as glucose source through catalytic hydrolysis assisted by ultrasonic (sono-hydrolysis). Besides, natural sand-based silica is raw material for zeolite synthesis. The purpose of the study was to do two things: i) characterize HY-zeolite made from and ii) determine whether or not effective sono-hydrolysis banana midrib. There a total four processes that were carried out, including extraction silica, synthesis HY zeolite, iii) process, iv) content test. results gain findings X-ray florescence </span><span>(XRF), diffraction (XRD), scanning electron microscopy (SEM), fourier transform infrared (FTIR) on are 2.3 Si/Al, obtained 2 theta d-spacing data similarities HY-zeolite, formed T-O-T, O-T-O (T = Si/Al), Si-OH groups respectively; with hydrolyzing cellulose into at maximum temperature time, 55 °C 6 hours.</span>
