  fluidized catalytic
Particle shape characterization of fluidized catalytic cracking catalyst powders using the mean value and distribution of shape
      
short/long ratio (SM), roundness (R) and concavity (CA), are able to describe the particle shape of fluidized catalytic cracking (FCC) catalysts in three principal aspects.
      
Nearly all other petroleum refineries include a fluidized catalytic cracking unit, and this unit is generally the largest-emitting unit at a refinery.
      
Traditionally, propene is a side product formed in ethylene steam crackers and fluidized catalytic crackers.
      
The purpose of the fluidized catalytic cracker is to convert heavy hydrocarbons, which have very low value, to higher value lighter hydrocarbons.
      


Some energy saying measures were carried out in the FCC unit of the 2nd Refinery during 1980,including:the use of CO-combustion promotor,energy recovery from flue gas,rearrangement of heat exchanges,steam generation by waste heat,and boiler feed water preheat by low-temperature effluents,resulting a decrease of energy consumption by 65×10~4 kcal/ton of feed.

石油二厂流化催化裂化装置在1980年又进行了节能技术改造.主要项目是:采用助燃剂的完全再生,烟气能量回收,换热流程调整,余热发生蒸汽,以及锅炉水预热回收低温位热等.通过改造,装置能耗下降到65万千卡/吨原料油.

The application of fluidization technology in China's petroleum refining indus try was summerized with fluid catalytic cracking as example. The development and improvement of fluidization technology realized in the type of reactor and regenerator beds, the conveying of fluidized solids, the separation of fluidized solids from gases, the heat transfer in a fluidized bed, and fluidization reaction engineering during the last 20 years were reviewed and illustrated with certain details. At present, the fluidization technology in China is still lagging behind the advanced world level. Extensive research work should be continued in the improvement of contact between gas and solid, reaction engineering, dust recovery,fluidized conveying at high flow rate, test and measurment of industrial fluidized bed, and the wear in fluidized bed and wear-resisting materials, so as to successfully develop a novel fluidization process.

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...

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 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。
