| 摘 要： | 以塔河减压渣油、催化裂化油浆及预加氢催化裂化油浆为原料，考察了原料油性质对油煤共炼反应过程和结果的影响，并通过连续进料装置加以验证。采用塔河减压渣油为原料时，油煤共炼反应难以在较高苛刻度下进行，在反应温度为（基准+30）℃时大于524 ℃组分的转化率为62.24 %时，生焦率为5.49%，影响反应的进行。加入FCC油浆后，油煤共炼可以在更高的温度下反应，从而提高重质组分转化率。加入预加氢的FCC油浆后，油煤共炼可以继续提高反应温度，在反应温度为（基准+45）℃时大于524 ℃组分的转化率提高至83.58%，生焦率为2.31%。在连续进料装置上的实验结果表明，以劣质渣油，煤粉及催化裂化油浆为原料的油煤共炼工艺可以实现渣油和煤的同时转化。

INFLUENCE OF OILS ON OIL-COAL CO-PROCESSING |
| |
| Abstract: | The Influence of different feed oils(Tahe vacuum residue, FCC slurry oil and hydrogenated FCC slurry oil) on oil-coal co-processing was investigated in a pilot plant. The results show that it is difficult to conduct the coprocessing reaction under severe conditions for mixture of Tahe vacuum residue and coal. The coke yield is up to 5.49% when the conversion of >524 ℃ fraction reaches 62.24%, and that additon of FCC slurry could promote the conversion of ＞524 ℃ in the mixture at higher reaction temperature. Under even higher reaction temperature, the cracking rate of ＞524 ℃ fraction in the oil-coal slurry can reach to 83.58% and the coke formation be effectively controlled to 2.31% when the pre-hydrogenated FCC slurry is added. The pilot plant results showed that coal powder and residue can convert into liquids simultaneously using the mixture of vacuum residue, FCC slurry oil and coal powder as feed. |
