Abstract:
This work studied the catalytic transfers hydrogenation (CTH) of furfuryl alcohol (FOL) to y-valerolactone (GVL) using Cu-based catalysts. The different charges balancing cation of Y zeolite (NH4+Y and HY) was comparatively studied the HY (Si/Al = 3.5) shows higher catalytic performance than NH4+Y (Si/Al = 3.5) zeolite. Moreover, 5%Cu/Y-IE catalyst shows higher catalytic performance than 5%Cu/Y-IM. However, increasing the amount of Cu loading from 5 to 10% (10%Cu/Y-IM) led to low catalytic activity since the agglomeration of Cu particles blocking some pore of Y zeolite. Therefore, highly dispersion of Cu on phyllosilicate (CuPS) structure is one of the good candidate catalysts for CTPI of FOL to GVL. The 30%CuPS exhibits high FOL conversion (71%) with low GVL yield (49.4%). Hence, various secondary metals such as Ni, Ag, and Zn were modified on CuPS to improve the catalytic performance of CTFI of FOL to GVL. The 1%ZnCuPS shows the highest catalytic performance (FOL conversion 84%, GVL yield 57%) than other secondary metal catalysts at the beginning. The synergetic effect between Zn and Cu increases the strong acid strength with high LA/BA ratio resulting to promote the highest catalytic performance. Moreover, to improve more the GVL selectivity from the solvent effect was also studied
