在温度为 2 90～ 360K ,氧气压力为 0 .10～ 0 .2 5MPa、无光照和Cu催化条件下详细研究了大庆直馏柴油和焦化加氢柴油吸氧速率和吸氧加速率的变化规律。结果表明 ,两种柴油的吸氧速率和吸氧加速率随时间的增长而逐渐减小 ,随氧气压力或温度的升高而迅速增大。温度和氧气压力越高或时间越长 ,柴油吸氧速率和吸氧加速率的变化幅度越大。柴油的吸氧速率和吸氧加速率在短时间 ( <30h)或高氧气压力 ( >0 .15MPa)或高温 ( >330K)时的变化幅度较大 ,焦化加氢柴油的 (起始 )吸氧速率和 (起始 )吸氧加速率远高于直馏柴油。
The changes of oxygen uptake rate and oxygen uptake rate of Daqing straight-run diesel oil and coker hydrogenated diesel oil were studied in detail under the condition of the temperature of 2 90 ~ 360K, oxygen pressure of 0 ~ 10 ~ 0. . The results showed that the oxygen uptake rate and oxygen uptake rate of two kinds of diesel oil gradually decreased with the increase of time and rapidly increased with the increase of oxygen pressure or temperature. The higher the temperature and oxygen pressure or the longer the change rate of diesel oxygen absorption rate and oxygen absorption rate is. The rate of oxygen uptake and the rate of increase in oxygen uptake of diesel vary greatly over a short period of time (<30h) or at high oxygen pressures (> 0.15MPa) or at elevated temperatures (> 330K) Oxygen rates and (initial) rates of oxygen uptake are much higher than for straight run diesel.
