Iron-substituted MFI, Y and USY zeolites prepared by two preparation routes-classical ion exchange and the ultrasound modified ion-exchange method-were characterised by micro-Raman spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and ultraviolet (UV)/visible diffuse reflectance spectroscopy (UV/Vis DRS). Ultrasound irradiation, a new technique for the preparation of th...
Catalytic and noncatalytic copyrolysis of plastic heavy oil was studied using thermogravimetric analysis (TGA), pyrolysis reactor experiments, GC the formed liquid. As revealed by TGA predegradation as a pretreatment method had further lowered decomposition temperature polypropylene– (PP?) bitumen mixtures reduced severity catalyst deactivation coke. The presence PP in increased liquid yield de...
