Abstract: The invention relates to the preparation of carboxylic acid esters compounds, biodiesel (B) from microalgae, for use as a biofuel for compression type ignition. The objective is achieved through a hydroesterification process of a microalgae biomass (MU) comprising a hydrolysis stage and the esterification stage by means of heterogeneous catalysis. The wet microalgae biomass (MU) is the result of a process of cultivation concentration and is hydrolyzed directly in a hydrolysis column (20). Fatty acids (C), water (A) and raw glycerin (G) are obtained following the hydrolysis. The fatty acids (C) are esterified by reactive distillation in the presence of an impregnated heterogeneous catalyst (I).

Abstract: An improved cyclone system for disengaging solid and gaseous particles in fluid catalytic cracking (FCC) processes with reduced coke formation in disengager vessels, without favoring release of the disengaged catalyst into cyclones in subsequent stages, said system comprising legless cyclones 42 fitted with external collector pipes 43, is described. The collector pipes 43 optimize the purge of gases coming from the disengager vessel 49, reducing the time the hydrocarbons remain inside said disengager vessel 49, thus preventing overcracking and subsequent coke formation. Positioning of the external collector pipes 43 prevents release of the disengaged catalyst into cyclones in subsequent stages. The present invention also relates to a process and device for disengaging solid and gaseous particles in fluid catalytic cracking (FCC) processes, reducing coke formation in disengager vessels and minimizing the release of catalyst into consecutive stages, said process and device being part of the system of the present invention.
