The biorefinery is an important approach for the current needs of energy and chemical building block syntheses. 5-hydroxymethylfurfural (HMF) is considered an important renewable building block for the production of levulinic acid and furan derivatives due to its potential availability from carbohydrates such as glucose and sucrose. In the present study, mesoporous zirconium phosphate catalysts (ZP) have been used for the synthesis of HMF from carbohydrates in aqueous media. ZP prepared hydrothermally using P123 as structure-directing agent, calcined at 500–800oC. HRTEM image reveals the presence of worm like highly monodispersed pores. BET surface area and total acid sites of ZP catalyst decreased with increasing calcination temperatures, and calcination temperatures have strong influences on the catalytic activity of ZP. The ZP catalyst, calcined at 600oC, showed ~86% conversion of glucose with maximum HMF yield (~52%) at 155oC within 6 h seems to be beneficial for HMF synthesis. |
