减压渣油生产环保橡胶油与重交沥青的研究

Study on the Process of Environment-friendly Rubber Oil and Heavy Duty Paving Asphalt by Vacuum Residue

以环烷基减压渣油为原料,通过丙烷脱沥青、糠醛精制与沥青调合工艺生产环保橡胶油与重交沥青。研究结果表明:以环烷基减压渣油为原料,通过丙烷脱沥青可以得到品质较好的轻脱沥青油及脱油沥青;以轻脱沥青油为原料,通过单塔糠醛精制可以生产CA值13%以上的环保橡胶油,通过双塔糠醛精制可以生产CA值23%以上的高芳环保橡胶油;以脱油沥青为原料,通过沥青调合工艺,可得到满足交通部A级道路石油沥青指标要求的50号和70号重交沥青。

Environment- friendly rubber oil and heavy duty paving asphalt were prepared through propane deasphalting,fur- fural refining and asphalt blending process with naphthenic vacuum residue. The results showed that, the light deasphalted oil and deoiled asphalt could be obtained through the propane deasphalting with the naphthenic vacuum residues;the envi- ronment -friendly rubber oil with CA value more than 13 % could be obtained from the light deasphalted oil through the furfu- ral refining of single extracting tower; the environment -friendly rubber oil with CA value more than 23% could be obtained from the light deasphalted oil through the furfural refining of twin extracting towers; AH -50 and AH -70 heavy duty paving asphalts that met the requirements of the Ministry of Communications were obtained through asphalt blending process with deoiled asphalt as raw material.
