网页2018/11/15 · Nickel/cerium–zirconium oxide (Ni/Ce50–Zr50) and manganese promoted Ni/Ce50–Zr50 (Ni–Mn/Ce50-Zr50) catalysts were prepared using an impregnation method and used in the dry reforming of methane. The catalysts were characterized by H2 temperature-programmed reduction, transmission electron microscopy, X-ray

网页1984/07/01 · Methanobacterium thermoautotrophicum when grown on ordinary culture medium has a tough cell wall which is lysozyme-resistant and difficult to disrupt by physical means. The cell wall, however, can be weakened by the addition of D-sorbitol to the growth medium and the organisms form protoplasts after
