Coprocessing of coal and oil sand bitumen

Go-processing of Battle River coal and Cold Lake oil sand bitumen from Canada was carried out in the presence of Ni-Mo, Go-Mo and red-mud/sulfur catalysts under reaction conditions of 400-450 degrees C, 10-120 min and 22-23 MPa of reaction hydrogen pressure by using a 500 ml shaking-type autoclave. The conversion of Battle River coal during the coprocessing was 97.1 wt% (daf) at 450 degrees C for 121 min with Ni-Mo catalyst, higher than 95.7 wt% (daf) at 450 degrees C for 120 min with red-mud/sulfur catalyst and anthracene oil. Cold Lake oil sand bitumen was excellent solvent to liquefy Battle River coal comparing with anthracene oil. In the presence of Ni-Mo catalyst during the coprocessing,the hydrogen consumption was nearly the same as that with red-mud/sulfur catalyst. Ni-Mo catalyst gave higher conversion of Battle River coal in the initial stage of the reaction than red-mud/sulfur catalyst. Ni-Mo catalystalso showed good activities far removal of asphaltene and heteroatoms from Battle River coal and good hydrogen availability. Moreover, the upgrading reactions of oil products such as hydrogenation, removal of heteroatoms and lowering molecular weight proceed at 450 degrees C.
