“…The yield of coke formation from acetol is generally low (<4 wt%) in this work compared to coke yields indicated for other model compounds besides alcohols (see Table S1). We note that Chen et al [36] reported a higher yield of coke (~11 C%) and a lower yield of liquid product (9.5 C%) when upgrading acetol over HZSM-5 (Si/Al ~25) at 500 °C. This indicates that a lower A:C ratio and/or higher W/F ratio was applied in their work, albeit the used catalyst mass unfortunately was not reported [36].…”

“…At temperatures above 370 °C, the reaction of acetic acid over HZSM-5 showed a high selectivity to iso-butene and acetone, which further react towards aromatics. Aldehydes show a low reactivity to hydrocarbons over HZSM-5, with a noticeable deactivation caused by coke deposition [32,[34][35][36].…”

“…Glycolaldehyde was shown to yield furans such as furanone below 300 °C, while at >400 °C further reactions to aromatics occurred [37], and general the conversion of model compounds and the yield of aromatics tend to increase with temperature. Chen et al [36] reported a higher yield of coke (~11 C%) and a lower yield of liquid product (9.5 C%) when upgrading acetol over HZSM-5 at 500 °C, with 68% of the liquid products attributed to aromatics (incl. polyaromatics).…”

“…In addition to the reactant type and temperature, coke deposition on acid catalysts also depends on the content of steam (MMP dehydration product) in the reaction medium. In this regards, steam inhibits coke formation as follows: (i) by stripping coke precursors; and (ii) by competing with the reactants and intermediates from the cracking and coke formation reactions in the adsorption on the zeolite acid sites. ,− …”

The catalytic cracking of 2-methoxy-4-methylphenol (MMP) and of a mixture of this compound (20 wt %) with nhexadecane (C 16 ) has been conducted in a CREC Riser Simulator Reactor at 400−550 °C using an equilibrium FCC commercial catalyst. The MMP and C 16 have been selected as model compounds of bio-oil and vacuum gasoil (VGO), respectively. The analyses of the conversion and product lump yields (dry gas, LPG, gasoline, and coke) have showed that there were synergistic effects between the reactions of the two feeds. The main synergistic effect is the reduction of the yield of coke with respect to that obtained with the individual feeds, as a consequence of the effect of the hydrogen-transfer reactions and the presence of steam on the coke formation mechanisms. The lower deactivation of the catalyst brings a lower yield of dry gas and a higher of gasoline. As a result of the study using model compounds, it is anticipated that the reduction of the catalyst deactivation is a favorable factor in the upgrading of bio-oil together with VGO in FCC units.
