Topic: 
Water and wastewater reuse
Mining wastewaters, containing heavy metals such as copper (Cu) and zinc (Zn), have a huge impact on the environment due to they are not biodegradable and tend to bioaccumulate in plants or living organisms. Therefore, in this work the performance of ion-exchange and solvent-impregnated resins were...Read more

A simple and flexible flowsheet process for recycling efficiently and selectively metals from spent fluid cracking catalysts

(Corresponding) Soares H., (Corresponding) Sadeghi M., (Corresponding) Jesus J., (Corresponding) Pinto E., (Corresponding) Almeida A.
Topic: 
Solid waste management
Fluid cracking catalysts (FCCs) are used in the oil industry to crack large molecules into smaller hydrocarbons of interest, such as gasoline and other products. Considering the large volume of FCCs waste generated on a yearly basis (about 20 thousand tons of spent FCCs worldwide) as well as its...Read more
