An important category of glycerol derivatives, having multiple practical applications, are its esters with acetic acid (acetates or acetins). The most common preparation method of glycerol acetates is the direct esterification of glycerol with acetic

The present paper evaluates the feasibility of a process flowsheet for butanol bioproduction, as pure compound or as a blend with the biodiesel used as the liquid-liquid extraction (LLEx) solvent. In order to evidence this aspect, a modeling and simu

The paper presents an industrial case study. Crude distillation unit (CDU) and delayed coking unit (DCU) are important plants in oil refineries, presenting huge energy consumption, especially due to high flowrates of process material streams. Any acc

A new sustainable process to produce tert-amyl-methyl-ether (TAME) using as feedstock enriched C 5 fraction (LCN – light cracking naphtha) from catalytic cracking (FCC) is developed. Existing technologies are based on methanol (MeOH) separation by

Catalytic distillation (CD), involving reaction and separation in the same unit, is possible and beneficial when both volatility of reactants is close each other, but quite different from the volatility of products, and the conversion is limited by c
