Biofuel is one type of alternative renewable fuel, which has minimal toxicity or non-toxic and environmental friendly. Green and renewable sources of biomass (carboxylic acids, lignocellulosic feedstock) had been used for the production of liquid fuels and chemicals, which may decrease fossil oil consumption and greenhouse gas emission. This work aimed to assess the conversion and selectivity for the production of biofuels using desilicated H𝛽 in Microwave Irradiated (MWI) reactor. Different lignocellulosic biomass derived feedstock like levulinic acid, valeric acid, succinic acid and oleic acid (4-oxo pentanoic acid (oPA), pentanoic acid (PA),butanedioic acid (BA), and Octadecenoic acid) were esterified and ketalized with primary and secondary alcohol in presence of desilicated Hβ (D-H𝛽) catalyst in conventional as well as MWI reactor. Catalyst desilicated Hβ was characterized by deferent technique. Acidity of D-H𝛽 by NH₃-TPD, average particle size by DLS, SEM & TEM, framework confirmation by XRD & FTIR, while surface area, pore size and pore volume were measured by BET method. Reaction temperature and microwave power were optimised. At optimised condition, the reaction parameters such as reaction time, selection of catalyst, molar feed composition (acid:alcohol) were systematically investigated to achieve maximum selectivity and conversion. Esterification and ketalization reactions produced variety of chemicals, such as levulinates, succinates, valerates, diesterand ketones, biodiesel additives and α-methyl-γ-butyrolactone, furanone, dioxonone propanoate, methyl oleate, laurate, tridecanoate, valuable intermediates to biodiesel additives. Product distributions based on the catalyst/solvent properties, nature of reaction, the reaction mechanism, reaction paths and kinetics were also studied. It showed that the higher acidity and mesoporosity generated in D-H𝛽 and chain length of alcohols had great effect on the reaction mechanism, rate of the reaction and product distributions.
