The aim of this review is to discuss the most relevant chemical routes for converting furfural to chemicals and to biofuels and additives.

This review revises the advances in the chemocatalytic processes for producing renewable carboxylic acids for the synthesis of bio-based polymers and proposes the actions to overcome the problems threatening their technical and economic viability.

This review is aimed to be a brief tutorial covering the deactivation of solid catalysts in the liquid phase, with specific focus on leaching, which can be especially helpful to researchers not familiarized with catalytic processes in the liquid phase.
