dc.description.abstractConcerns towards diminishing fossil resources compel the chemical industry to explore alternatives for basic chemical productions. Carbohydrates derived biomass are promising alternatives for sustainable supply of fuels and valuable chemicals due to their abundant and relatively inexpensive properties. Carbohydrate such as glucose is a compound from which various bio-based chemicals can be derived. Among those chemicals, levulinic acid (LA) has received significant attention as platform chemicals for synthesizing a broad range of bio-based fuels. The conversion of carbohydrates to LA have been conducted in water in the presence of various catalysts, including homogeneous and heterogeneous catalysts. In this study, a new zeolite immobilized ionic liquid (HY-IL) catalyst has been explored for catalytic conversion of glucose to LA. The catalyst was prepared by immobilizing an acidic ionic liquid; 1,4 methylsulfonic acid imidazolium tetrachloroaluminate ([MSIM][AlCl4]) into HY zeolite with weight ratio 1:2 of ionic liquid to zeolite. The synthesized [MSIM][AlCl4] was characterized using CHNS elemental analysis to validate the prepared [MSIM][AlCl4]. Meanwhile, the parents HY zeolite and HY-IL were characterized using N2 physisorption and temperature desorption of ammonia (NH3-TPD) to determine their surface area and acidity, respectively. From the characterization results, the prepared [MSIM][AlCl4] was validated, the surface area of HY-IL was decreased, while the acidity of HY-IL was increased compared to the parent HY zeolite. The catalytic testing were conducted at 160 °C for 5 h using 0.4 g of catalyst and 0.4 g of glucose. HY-IL gave the highest LA yield (21%) compared to parent catalysts; [MSIM][AlCl4] (23%) and HY zeolite (traces). The high catalytic performance of HY-IL was due to its high concentration of active acid sites compared to HY zeolite. This study demonstrated the potential of zeolite immobilized ionic liquid as a catalyst for biomass transformation to platform chemicals under mild process conditionen_US
