Shengli lignite liquefaction under syngas and complex solvent
摘要
Abstract
The liqeu faction ofS hengli lignite ( SL ) were tsu dei d in the system of syngas ( H2+CO ) and complex solvent (H2O+THN) and the system of hydrogen (H2) and tetralin (THN).Asphaltene (AS) and preasph altene ( PA) from the two systems were characterized by FT-IR.The results soh w thta both conversion and oil yield of Shengli il gin te liquefaction in the ( H2+CO)/( H2 O+THN) syts em are significantly higher than those in the H2/THN syset m.The covn eris on and oil yield under syngas ( H2∶CO=1∶1 ) and complex solvent (THN∶H2O=1∶1) reach respectvi ely 88.79%and 55.47%ta 400℃, 4 MPa and 30 min.The differences in the conversion and oil yield between the (H2+CO)/(H2O+THN) andH 2/THN systemsa re 8.00% and 7.54%,r espectively.This suggests that the water-gas shift reactoi n can produce active hydrogen in the ( H2+CO)/( H2 O+THN) system , which benefits the hydrogenation of SL and PA.Meanwhile, THN can stabilize the free radicals from SL pyrolysis and dissolve the products ( AS and PA) from SL liquefaction.The synergistic effect of two factors results in the improvement of conversion and oil yield.This study hs ows that it is a new lignite liquefaction technology using the ( H2+CO)/( H2 O+THN) system.关键词
