摘　　要：本文采用吡啶吸附的傅立叶变换红外光谱法 ( Py- FTIR)对三类典型工业 FCC催化剂基体的新鲜样品及其水热处理样品 (模拟平衡态 )进行了详细的酸性表征 ,并与基体的催化裂化反应性能尤其是氢转移反应能力进行了关联研究 ,发现基体的催化功能与其平衡态直接相关 ,而不是其新鲜态。Acidity of the fresh and hydrothermal treated samples of three typical FCC catalyst matrix was characterized using Py FTIR.The acidity of the matrix was correlated with its catalytic property for catalytic cracking,especially for hydrogen transfer reactions.It was found that catalytic property of the matrix was directly related to acidity of its equilibrium sample,not fresh one.
