In this paper, the shrub residues as raw materials, were produced to upgraded bio-oil by fast pyrolysis technology and online catalytic cracking in a 5 kg/h fluidized-bed reactor. The quality of upgraded bio-oil was significantly improved after online catalytic cracking, the oxygen content was 31.83 %, the water content was 22.15 % and the liquid yield was 43.42 % after online catalytic cracking ( 500 C). After online catalytic cracking, the content of organic acids decreased to 3.3 %, the content of phenols increased to 40.10 % and the content of one or two benzene rings compounds increased to 16.60 %. This was attributed that zeolite HZSM-5 had the catalytic reforming and cyclization functions.
