    摘要: The present invention pertains to Mg—Al anionic clay having 3R2 stacking. This new polytype of anionic clay has a three-layer repeat, but it has a different interlayer arrangement than the conventional 3R1 hydrotalcite. Said new polytype can be applied in all applications described before for the conventional 3R1 polytype anionic clay such as in catalyst compositions, catalyst additive compositions, catalyst supports, absorbent compositions, stabilizer compositions and in medicaments.

    摘要: A catalytic converter for cleaning exhaust gas includes a first coating layer formed on a heat-resistant support, and a second coating layer formed on the first coating layer. The first coating layer contains alumina which supports palladium. The second coating layer contains Ce—Zr complex oxide which coexistently carries platinum and rhodium, and Zr—Ce complex oxide which differs in composition from the Ce—Zr complex oxide and which coexistently carries platinum and rhodium.

    摘要: A process for improving the stability and/or preventing the deactivation of catalyst in processes of continuous manufacture of acetic acid and/or methyl acetate includes a first, reaction step wherein at least one methyl formate isomerization reaction is carried out in a liquid phase reaction medium, in the presence of carbon monoxide and of a catalytic system including at least one halogenated promoter and at least one iridium-based catalytic compound, and, a second, flash step in which partial vaporization of a reaction medium originating from the first step is carried out in a flash separator. In a non-vaporized liquid fraction resulting from the partial vaporization in the flash separator, an overall content of formic acid and methyl formate is maintained at least equal to 1% by weight of said non-vaporized liquid fraction.
