- 摘要：将FCC油浆与DCC重油按不同比例与西湾煤混合，研究DCC重油与煤共炼技术的可行性。试验结果表明，用纯DCC重油作为煤油共炼原料，其反应效果与用纯FCC油浆作为煤油共炼原料效果相当，在煤浓度 45%、反应温度 468 ℃、反应压力 20 MPa、氢油比 2 000 L/kg、空速 0.5 h-1条件下，DCC重油与煤共炼，煤的转化率>90%，>525 ℃的组分（不含固）转化率接近90%，液体收率≥70%。因此，DCC重油作为煤油共炼的原料是可行的，且在煤浓度为45%时，DCC重油和FCC油浆不同比例混合，对反应的顺利进行和结果影响较小。
Abstract: FCC slurry and DCC heavy oil were mixed with Xiwan coal in different proportions to study the feasibility of DCC heavyoil and coal co-smelting technology. The experimental results show that the reaction effect of using pure DCC heavy oil as the rawmaterial of kerosene co-refining is basically equivalent to that of using pure FCC oil slurry as the raw material of kerosene co -refining. Under the coal concentration of 45%, reaction temperature of 468 ℃, reaction pressure of 20 MPa, hydrogen-oil ratio of2 000 L/kg, and space speed of 0.5 h-1, DCC heavy oil and coal can be co-refined. The conversion rate of coal is higher than 90%,the conversion rate of > 525 ℃ components (without solids) is close to 90%, and the liquid yield is more than 70%. Therefore, DCCheavy oil is feasible as a raw material for kerosene co-refining, and when the coal concentration is 45%, DCC heavy oil and FCCslurry are mixed in different proportions, which has little impact on the smooth progress and results of the reaction.
