In this study, a carbon–based solid acid catalyst was prepared via hydrothermal carbonization method (HTC) using glucose and pyrolysed waste tyre as carbon precursors and aqueous solution of H2SO4 as sulfonation agent. Prepared catalysts were characterized by X–ray diffraction (XRD), scanning electron microscope (SEM), Fourier transform infrared FT–IR and Brunauer–Emmett–Teller (BET). As the result, catalysts were manufactured with the appropriate physical and chemical characteristics and high acidity. | Journal of Science and Technology 55 (1B) (2017) 145–151 A SYNTHESIS OF SOLID ACID CATALYSTS FOR USING IN HYDROLYSIS OF CELLULOSE FROM RICE STRAW INTO GLUCOSE T–Que Phuong Phan1, *, Sy–Nguyen Pham1, H–Khoi Nguyen Nguyen2, T–Ngoc Phuong Lieu2, Huu–Thien Pham1, Van–Qui Nguyen1, Dinh–Thanh Nguyen1 1 Institute of Applied Material Science, Viet Nam Academy of Science and Technology 1 Mac Dinh Chi street, Ben Nghe Ward , District 1, Ho Chi Minh City, Vietnam 2 Department of Inorganic Chemical Engineering, Faculty of Chemical Engineering, HCMUT–VNUHCM, 268 Ly Thuong Kiet Street, District 10, Ho Chi Minh City, Vietnam * Email: ptqp2106@ Received: 30 December 2016; Accepted for publication: 3 March 2017 ABSTRACT In this study, a carbon–based solid acid catalyst was prepared via hydrothermal carbonization method (HTC) using glucose and pyrolysed waste tyre as carbon precursors and aqueous solution of H2SO4 as sulfonation agent.

INTRODUCTION Biomass is one of the most promising renewable and sustainable alternative for energy and chemical production. As an energy source, biomass can be utilized without depleting the existing reserves. Current research interest is, therefore, to convert biomass to fuels and chemicals [1]. In recent years, many researchers have found alternative source material for the production of biofuel to replace fossil fuels urgently. The use of materials derived from biomass to produce biofuels and chemicals for plastics as well as pharmaceuticals not only enhances the value of the agricultural production but also contributes to solving environmental pollution issues and ensuring
