Highly efficient micro-meso acidic H-USY catalyst for one step conversion of wheat straw to ethyl levulinate (biofuel additive).

Ethyl Levulinate (EL), biofuel additive can blend up to 20% with biodiesel to improve its fuel properties. Till the
date, there are reports on homogeneous catalysts (H2SO4, ionic liquid) for synthesis of EL from raw biomass like
wheat straw. To best of our knowledge, there is no single report on heterogeneous catalyst for one step synthesis
of EL directly from wheat straw. This work is a successful attempt to use heterogeneous micro-meso acidic H-USY
(post dealumination and desilication) for direct one step conversion of wheat straw to EL with higher EL yield
24.5 wt%, which is probably the highest so far.
