ALKALI METAL-CARRYING SUBSTANCE, AND ITS USE AS CATALYST

摘要

PCT No. PCT/JP85/00291 Sec. 371 Date Jan. 23, 1986 Sec. 102(e) Date Jan. 23, 1986 PCT Filed May 28, 1985 PCT Pub. No. WO85/05562 PCT Pub. Date Dec. 19, 1985.An alkali metal-supported substance comprising a calcination product of a hydrotalcite-like compound having Mg as a divalent metal and a carbonate ion as an anion and an alkali metal supported on the calcination product. When this substance is treated with a gas containing molecular oxygen, part of the alkali metal is converted to its oxide to give a more stable substance. These substances act, for example, as an isomerization catalyst for olefins.
