With diesel fuel oil as the feedstock,nano-NiO as the catalyst, the cracking experiment of heavy diesel oil was carried out in the small continuous tube cracking furnace at the laboratory. Under different conditions, the influence of cracking temperature, retention time, water/oil mass ratio and solvent/oil ratio on the yield of ethylene were investigated.Through variance analysis ,the optimum technological conditions for diesel fuel cracking were determined as follows:cracking temperature 750℃, residence time 4.0 s,water/oil mass ratio 3:1,and solvent/oil mass ratio 12:1.Under above conditions, the yield of ethylene was 31.27%.
