This paper shows the results of the catalytic conversion of DL-limonene using heteropolyacids catalysts (HPAs) supported for the production of aromatic compounds oh high industrial value. The experimental tests were performed for select the best active phase
the best support and in addition to evaluate the influence of temperature
for conversion and selectivity; experimental tests were carrier out in a tubular fixed bed reactor
in operational conditions of temperature of 180
250 and 350 ºC
flow of inert gas of 155 Nml/min
relative pressure 0.5 bar
space velocity of 0.4
mass flow of DL-limonene (98% purity) 6.3854 g/min
vaporization temperature of 280 ºC
and reaction time of 5 minutes. Four types of catalyst were used in the catalytic test. The results showed that the active phase H4PMo11VO40 had the best conversion
and the best support was SBA-15. It was found that larger pore size and surface area of the support selectivity is better
greater number of Lewis acid sites and acidity increase greater conversion to aromatic compounds at the same temperature. Comparing both the acidity of the catalyst and the conversion of the molecule (DL-limonene) to aromatic compounds at different temperatures
it was obtained that at a moderate acidity with a temperature of 250 ºC the conversion and selectivity are favored
