Abstract
In this study, fluidized-bed pyrolysis has been conducted in order to recover the bitumen contained in the oil sand. Canada Alberta oil sand contains 11.9% of bitumen and the bitumen-derived heavy oil produced in fluidizedbed tends to be upgraded relative to the bitumen. The continuous operation has been performed using $N_2$ as a fluidization gas at 1 atm and $500^{\circ}C$ in a reactor of 170 cm height. The results showed 87.76% of bitumen conversion, where liquid products are 74.45% and gas products are 13.31%. $H_2$, $O_2$, CO, $CO_2$, $CH_4$, and NO and $C_1{\sim}C_4$ hydrocarbons in the gas products were analyzed by on-line gas analyzer and gas chromatography, respectively. The pyrolysis oil was analyzed by using proximate analysis, heavy metal analysis, SIMDIS, asphaltenes, and heating value. By SIMDIS analysis, naphtha was 11.50%, middle distillation was 44.83% and heavy oil was 43.66%. It was obvious that the pyrolysis oil was upgraded compared with bitumens.
