Abstract

The precursor of coke on the catalyst HZSM5 used in biooil catalytic cracking upgrading was analyzed by means of TGA, FTIR and CNMR. Precursors of coke deposited in the pore of the molecular sieve were mainly aromatic hydrocarbon with the boiling point ranging from 350 °C to 650 °C.Those on the outer surface of the pallet precursor were identified as saturated aliphatic hydrocarbons with the boiling point below 200 °C.
