With the aim to solve the problems of coking deactivation of catalyst and low yield of refined oil in catalytic cracking upgrading process of bio-oil

an on-line catalytic cracking upgrading scheme assisted by NTP combining with zeolite catalyst was proposed.An NTP assisted catalytic cracking reactor was designed according to the principle of dielectric barrier discharge

and the effects of catalyst loading

in catalyst

system pressure

operating voltage and frequency on the reactor’s performance were studied experimentally.Results reveal that the incipient discharge voltage is significantly decreased after catalyst addition

the catalyst’s molar ratio of SiO

has small impact on the discharge power

the system pressure and operating voltage are the main factors influencing the discharge power

and the temperature of catalyst is dramatically affected by the molar ratio of SiO
