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

Topic:
Solid waste management
Microporous 12-ring zeolite Beta was impregnated with palladium and evaluated in the cracking of low-density polyethylene (LDPE) cracking. In addition to the catalytic measurements the materials were characterized by X-ray diffraction, chemical analysis and nitrogen adsorption, electron microscopy...Read more
