摘要: 以塔河减压渣油(简称塔河减渣)为原料,在实验室小型试验装置和中型连续试验装置上,对在较高温度条件下催化临氢热转化加工塔河减渣的工艺操作条件及改质效果进行了系统研究。采用高分散的油溶性催化剂,在高压釜反应器中考察了反应温度、反应压力、催化剂添加量、溶剂油添加量、反应时间以及助剂添加量对塔河减渣催化临氢热转化反应的转化率和缩合率的影响,优化了操作参数。在优化的操作条件下,进行了塔河减渣催化临氢热转化中型试验,得到初馏点大于524 ℃组分的裂化率为85.2%,馏分油收率为80%,金属(Ni+V)和沥青质脱除率均大于90%。

Abstract: Taking Tahe vacuum residue as a raw material, the operation conditions and upgrading effect of thermal-cracking in the presence of hydrogen at high temperature were tested in autoclave and pilot plant with highly dispersed oil-soluble catalyst. The effect of reaction temperature,pressure,reaction time, catalyst dosage,amount of solvent oil and additive on the residue cracking conversion rate and condensation rate were investigated. The pilot test results showed that under the optimized conditions,the cracking rate of the fraction > 524℃ of Tahe residue was more than 85.2%,the yield of distillate oil was 80%,and the metal (Ni+V) and the asphaltene removal rate were both greater than 90%.

Key words: Tahe vacuum residue, high temperature conversion, catalytic thermal-cracking in hydrogen
