在柴油吸氧安定性能研究与评价的基础上 ,在 2 90～ 3 60K、0 .1 0～ 0 .2 5MPa氧压、无光照和Cu催化条件下详细考察了大庆直馏柴油 (SRDF)和焦化加氢柴油 (HCDF)吸氧速率和吸氧加速率的变化规律。研究结果表明 ,在给定的条件下柴油的吸氧速率 (vt)和吸氧加速率 (vtt)随时间的增长而逐渐减小 ,随氧压或温度的升高而迅速增大。温度和氧压越高或时间越长 ,vt 和vtt的变化幅度越大。vt 和vtt在短时间 (≤ 3 0h)或高氧压 ( >0 .1 5MPa)或高温 ( >3 3 0K)时的变化幅度较大 ,而在长时间 ( >3 0h)或低氧压 (≤ 0 .1 5MPa)或低温 (≤ 3 3 0K)时的变化幅度较小。HCDF的 (起始 )吸氧速率和 (起始 )吸氧加速率高于SRDF。两者在吸氧速率和吸氧加速率之间存在较大的区别。
On the basis of the research and evaluation on the oxygen-absorbing and stable performance of diesel oil, the effects of SRDF and SRDF on the mechanical properties of Daqing straight-run diesel oil (SRDF) and Cu (superscript 2 +) were investigated in detail under oxygen pressure of 2 90 ~ 3 60K, 0. Variation of oxygen uptake rate and oxygen uptake rate of coking hydrogenated diesel oil (HCDF). The results show that under certain conditions, the oxygen uptake rate (vt) and oxygen uptake rate (vtt) of diesel fuel decrease with time, and increase rapidly with the increase of oxygen pressure or temperature. Higher temperature and oxygen pressure or longer, vt and vtt the greater the magnitude of change. vt and vtt in a short time (≤ 3 0h) or high oxygen pressure (> 0. 15MPa) or high temperature (> 3 0 0K) greater changes in the range, and in a long time (> 30h) or low oxygen pressure (≤0.115MPa) or low temperature (≤330K), the variation range is small. The rate of (initial) oxygen uptake and (initial) uptake of oxygen by HCDF was higher than that of SRDF. There is a big difference between the rate of oxygen uptake and the rate of oxygen uptake.
