In this paper, three kinds of MgO with different specific surface area were prepared, and their effects on the catalytic performance of nickel catalysts for the
SO2-4–Mo O3–Zr O2–Nd2O3/Si O2(SMZN/Si O2) catalysts for the production of biodiesel via both esterification and transesterification were prepared and charact
A series of phosphorus-modified PITQ-13 catalysts was prepared by wet impregnation of NH4H2PO4solution into an HITQ-13 parent. The catalysts were characterized
