DOI: 10.1007/s40242-018-7236-9
Abstract: A series of HZSM-5 zeolites modified with different amounts of phosphoric acid(P/HZSM-5) was pre-pared. The physicochemical features of the P/HZSM-5 catalysts were characterized via X-ray diffraction(XRD), N2 adsorption-desorption, NH3-temperature programmed desorption(NH3-TPD) and Fourier tranform infrared(FTIR)… read more here.
