Road-paving asphalt meeting the required specifications can be prepared by mixing coal tar with fluid catalytic cracker (FCC) bottoms and whole used tire, excluding steel belts, at proper ratios. AC-10 type asphalt has been formulated by adding 5% chopped whole used tire in a 50/50 coal tar-FCC bottoms mix and heating the mixture at 300-315℃ for 1 hour to ensure homogeneity and good quality. The group constituents of the final mixture are quite similar to those of conventional asphalts. The coal tar provides...

The group constituents of the final mixture are quite similar to those of conventional asphalts. The coal tar provides asphaltenes for thickening. The hardness of the mixture increases as the concentration of coal tar increases. The FCC bottoms provides resins and act as a dispersant to improve ductility. The used tire acts as a rubberizing agent for the improvement of asphalt properties by decreasing its temperature sensitivity and increasing its ductility. The use of coal tar and whole used tire saves petroleum residue, which can be upgraded to transportation fuels, and alleviates disposal problems of used tires.

把煤焦油、流化催化裂化(FCC)重油和全旧轮胎(除去钢带)按合适的比例混合,就可得到符合规格要求的铺路沥青。将混合物在300~315℃温度下加热1小时可以保证产品的均匀性和良好的质量。这种混合物的族组成与常规沥青很相似。用煤焦油和旧轮胎来生产沥青可以省出石油渣油来改质成为交通运输燃料,并可简化废轮胎的处置问题。

A novel technique has been developed to successively collect the fines, produced by the atrition of catalyst particles in aqueous suspension, as samples representing the outer shells of the particles. With this technique, a number of commercial equilibrium FCC catalysts were investigated. The experimental results show that in the process of residcrackitig,the intraparticle and interparticle distributions of coke on catalysts forresidual cracking are not uniform due to the presence and the coking reaction of unvaporized resids. However, for gas oil FCC, as a result of prevailing .vapor-phase reaction, the distributions, of, coke on catalysts are uniform both in intraparticle and interparticle. Additional information was derived from the analysis of contamination metal contents of samples taken primarily for coke content determination. The radial distributions of nickel on catalysts for both VGO and residual cracking are uniform.

本文建立了测定流化催化裂化(FCC)催化剂上的焦炭以及污染金属沿径向分布的一种新方法——研磨法。用这种方法考察了多种工业待生剂,取得了确定的结果,并从理论上初步探讨了提升管反应器中的传递过程和生焦反应。研究结果表明,由于液相组份的存在和反应,渣油裂化催化剂粒内和粒间的焦炭分布都是不均匀的,而汽相反应的瓦斯油裂化催化剂粒内和粒间的焦炭分布都是均匀的。污染金属镍在这两种类型的催化剂上的径向分布也都是均匀的。
