摘要

在CoCl2和MnCl2两种催化剂的作用下，对不同药剂鞣制的皮革进行了热解研究。用两种无机鞣剂(铬和钛盐)和两种有机鞣剂(戊二醛和甲基丙烯酸树脂)鞣牛皮样品。将样品浸泡在已知浓度的CoCl2或MnCl2溶液中。采用热重分析(TG/DTG)和快速热解(Py-GC/MS)评价了热解温度对热解产物的影响。对热解产物进行了多变量分析，证实了催化剂处理对皮革的影响。

Thermal Characterization and Pyrolysis of Waste Leather Treated with CoCl₂ And MnC₂

Leather tanned with different agents was pyrolyzed in the presence of CoCl2 and MnCl2 catalysts. A bovine leather sample tanned with two inorganic tanning agents (chromium and titanium salts) and two organic tanning agents (glutaraldehyde and methylacrylic resin) has been used in this study. The samples were soaked in solutions of CoCl2 or MnCl2 of known concentration. The influence on decomposition temperature and the resultant pyrolysis compounds has been evaluated by using thermogravimetric analysis (TG/DTG) and flash pyrolysis (Py-GC/MS). A multivariate analysis has been applied to the pyrolysis products obtained confirming the effect of the catalyst treatment on leather,
