Abstract
|
Regarding
the composition of the various feedstocks which should be hydrotreated in
order to obtain fuels with amount of sulfur less than 10 wt ppm, authors have
shown that the presence of traces of CO, a by-product from lignocellulosic
biomass feedstock conversion, inhibited the transformation of model compounds
representative of FCC gasolines and gas oils over CoMo-based sulfide
catalysts. Accordingly, this effect is more significant in the presence of
2-methylthiophene and 2,3-dimethylbut-2-ene representative of a FCC gasoline
than in the presence of dibenzothiophene and 4,6-dimethyldibenzothiophene
representative of a straight run gas oil, even if the operating conditions
are not the same.
This effect is attributed to phenomena of competitive adsorption between sulfur compounds, alkenes and CO on the catalyst surface. |
