摘要
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。
Under conditions of 290～360K,0.10～0.25 MPa,nonilluminant and copper catalyst,both rate and acceleration of oxygen absorption of Daqing straight run diesel fuel(SRDF) and hydrogenated coking diesel fuel(HCDF) were studied in detail.The results showed that both rate and acceleration of oxygen absorption gradually decrease with the time,while rapidly rise with increase of oxygen pressure or temperature.The higher the temperature and oxygen pressure or the longer the time,the greater the variations.Greater variations occurred in a short time(<30h) or at high oxygen pressure and high temperature.The initial rate and acceleration of oxygen absorption of HCDF are considerably higher than those of SRDF.
