一、前言在烃类蒸汽转化过程中,由于炭在催化剂表面沉积,使催化剂活性降低、床层阻力增加、催化剂寿命缩短,严重时会因催化剂破碎而导致反应管堵塞,故研制出一种抗炭能力强的催化剂是十分必要的。在评价催化剂时,必须准确测出催化剂中的炭含量。其炭含量的测定过去大都采用热重法、元

I. INTRODUCTION In the process of hydrocarbon steam reforming, due to the deposition of carbon on the surface of the catalyst, the activity of the catalyst is reduced, the resistance of the bed is increased, the life of the catalyst is shortened, and when the catalyst is broken, the reaction tube is blocked due to the catalyst crushing. Therefore, Carbon-based catalyst is very necessary. In evaluating the catalyst, the carbon content in the catalyst must be accurately measured. The determination of its carbon content in the past mostly used thermal gravimetric method, yuan
