制备方法与用途

水合碳酸铽概述

水合碳酸铽是一种稀土离子金属化合物。碳酸铽可溶于酸，并释放二氧化碳。高温下，碳酸铽分解生成铽的氧化物。有文献报道，水合碳酸铽可用于制备一种高效、稳定的铂基正构链烷烃芳构化催化剂。

应用

CN202010564426.5公开了一种高效的铂基正构链烷烃芳构化催化剂及其制备方法。该发明提供了一种铂基正构链烷烃芳构化催化剂，其特征在于包括以下组分（以重量份计）：铂盐0.01~2份、一种IV A族元素0.001~3.0份、一种稀土离子或碱土金属0~4.8份，所有组分均按金属量计算。通过将上述组分负载在KL分子筛上制得。

所述的稀土离子金属化合物包括硝酸铈、硝酸亚铈、氯化亚铈、硫酸亚铈、二氧化铈、草酸铈、氟化铈、硝酸镨、氧化镨、三氯化镨六水合物、乙酸镨水合物、氯化镨、氟化镨、硝酸钕、氧化钕、氢氧化钕、六水硝酸钐、氧化钐、水合氢氧化钐、氯化钐、氧化铕、硝酸铕、无水三氯化铕、硫酸铕、硝酸钆、氧化钆、氢氧化钆、氯化钆、氧化铽、硝酸铽、氯化铽、水合乙酸铽、三(环戊二烯基)铽以及水合碳酸铽。

本发明的有益效果包括：所得催化剂的铂颗粒尺寸小，活性位点Pt在KL分子筛上的吸附能力强，并且积碳在活性位PtxM团簇上的吸附能被减弱。这些特点有效解决了催化剂易积碳和稳定性不足的问题，提高了芳烃的选择性。

具体来说，本发明通过添加一种IV A族元素和一种稀土离子或碱土金属，减少了Pt颗粒的尺寸，增强了活性位点Pt在KL分子筛上的吸附能力，并抑制了PtxM团簇对积碳的吸附作用。这不仅有效抑制了Pt的团聚现象，提高了催化剂抗积碳性能；还实现了对Pt电子性质的适宜调控，使其更有利于烷烃芳构化反应的发生，同时抑制氢解或二次氢解反应的发生，从而显著提升了催化剂在芳构化过程中的性能和芳烃的选择性。

此外，本发明制备的催化剂特别适用于正构链烷烃的芳构化反应。对于C6~C8正构链烷烃，该催化剂能明显提高芳烃选择性和液收率，并表现出高稳定性，具有很好的工业化前景。
