چکیده انگلیسی
A catalysis process enhanced by pre-plasma for bio-fuel preparation was proposed. Three aspects were included: (i) the process was analyzed and optimized aiming at comprehensive evaluation index, (ii) the Ti/HZSM-5 was introduced under optimal conditions and mechanism was explored, and (iii) the catalytic stability was evaluated. The results showed catalytic temperature, catalytic height and discharge power had significant effects on the index and interactions were exist. Optimal conditions were catalytic temperature of 455â¯Â°C, catalytic height of 26â¯mm and discharge power of 30â¯W. The energy consumption of pre-plasma occupied 12.35% of the total. Ti modification decreased the bio-fuel yield from 15.05% to 13.77%, and the oxygen content and calorific value reached 10.95% and 35.50â¯MJ/kg. The total hydrocarbon content was 52.90% and desired monocyclic aromatic hydrocarbons occupied 64.22%, and 82.84% of hydrocarbons were concentrated in the C10-C13 range. The main oxygenates after upgrading were hydroxyl containing compounds, which were difficult to eliminate due to the high hydrophilicity. The upgrading processed in series, involving reactant activation, catalytic reactions and multiple interactions. The coking rate of spent catalysts decreased from 6.85% to 3.15% after Ti modification, even in the case of that the effective hydrogen to carbon ratio of reactants was lower.
