A bio-oil production process involving torrefaction pretreatment, catalytic esterification, pyrolysis, and secondary catalytic processing significantly reduces yields of reactor char, catalyst coke, and catalyst tar relative to the best-case conditions using non-torrefied feedstock. The reduction in coke ...
The influences of gas compositions on the rates of coke formation over a Pt–Sn/Al2O3catalyst are studied. The coke formed on the catalyst is characterized by thermal gravimetric analysis, IR spectroscopy, Raman spectroscopy and elemental analysis. Two kinds of coke are identified from the TPO ...
Coke formation over a series of dealuminated mordenites was investigated by in-situ IR spectroscopy using dealkylation/disproportionation of ethylbenzene as a model reaction. The rates of coke formation and catalyst deactivation increased with increasing acidity, i.e. number and/or strength of the aci...
