Abstract
Considering the current world crisis and definite future energy challenges,
biomass-to-fuel transformation is increasingly becoming important both to
the policy makers and to the industry. In this perspective, the valorisation
of oils and fats via transesterification/esterification reaction is an
attractive method for producing biodiesel with qualities suitable for diesel
engines. The recent interest indicated a significant shift to industrial
waste valorisation as another approach for achieving process eco-efficiency.
In this respect, the use of zeolite-based catalysts for the production of
biofuels is reviewed here, with a special emphasis on the utilization of
waste raw materials following the principles of green chemistry and
sustainable development. Zeolites are interesting due to their outstanding
catalytic properties, including the presence of intrinsic acid sites, simple
loading of base sites, shape-selectivity, and high thermal stability. Neat
zeolites or modified by the loading of active species are classified into
several groups following their origin. For each group, the most relevant
recent results reported in the literature are reviewed together with some
critical considerations on the catalyst effectiveness, stability,
reusability, and economy of synthesis. As an important part required for
understanding and optimization of the biodiesel production process, the
mechanisms of the reaction were discussed in detail. Finally, key
perspective directions for further research studies were carefully
identified and elaborated.
