沙特中质原油减渣及其丙脱沥青制取高等级道路石油沥青的研究

Study on production of paving asphalt from vacuum residue and propane deasphalt residuum of Saudi Arabian medium crude oil

以沙特中质油的减渣及其丙脱沥青为原料制取高等级道路石油沥青的研究表明,所制取的沥青产品,抗热老化性理想,性能指标在路面使用温度条件下比较稳定,使用性能与国外高等级道路石油沥青相当,符合国内、外有关的技术要求。

Using vacuum residue and propane deasphalt residuum of Saudi Arabian medium crude oil to produce paving asphalt, the study indicates that the produced asphalt have ideal anti-thermalaging property, its character is stable while the condition temperature change, its performance is equal to that of foreign asphalt and accord with domestic and external specification.
