【摘要】 本文首次合成出一类未见报道的三元金属复合柱交联蒙脱土催化剂（Ｎｉ－Ｃｒ－Ａｌ－ＣＬＭ）。通过镍、铬的改变来调变催化剂的表面酸性与孔结构。用ｘ－射线粉末衍射、吡啶吸附红外光谱测定催化剂的层间距及表面酸类型，并对催化剂中柱化液的Ａｌ３＋、Ｃｒ３＋、Ｎｉ２＋离子的配比，Ａｌ／Ｃｌａｙ比与反应活性相关联，确定了催化剂的最佳组成：Ａｌ／Ｎｉ＋Ｃｒ＝２．０（摩尔比）；Ｎｉ／Ｃｒ＝３／１及Ｎｉ／Ｃｒ＝１／１；Ａｌ／Ｃｌａｙ＝３．０（毫摩尔／克）。更多还原

【Abstract】 A kind of solid catalyst of hydroxy NiCrAl pillared clays was prepared for the first time.Surface acidity and pore structure were adjusted by means of changing Ni/Cr ratios.Basal spacing and types of surface acid were determined with x ray power differaction and IR spectra of adsorbed pyridine.When diffrent pillaring solution Al 3+ 、Cr 3+ 、Ni 3+ Cations ratio in pillaring solution and Al/clay are associated with reactive activity,the optima composition are determined as follows:Al/Ni+Cr=2.0(mol ratio),Ni/Cr=3/1 or Ni/Cr=1/1,Al/Clay=3.0(mmol/g).更多还原
