摘要:
采用硫碳仪、电感耦合等离子体发射光谱（ICP-OES）仪等仪器，对沸腾床渣油加氢催化剂进行了性质分析。结果表明：当利用石油醚清洗、硫碳仪测试温度为1 100 ℃，催化剂样品用量为0.05 g时，仪器能很好地检测出样品S和C质量分数；当除碳预处理的焙烧温度为800 ℃，并利用微波消解和ICP-OES法测定催化剂的含金属量时，结果重复性好，且废催化剂含Fe，Ni，V量明显高于新催化剂；利用数学分割和统计法测定催化剂长度时，结果重复性好，且相比新催化剂，废催化剂长度明显呈现变短的趋势。
Abstract:
The properties of ebullated bed residue hydrogenation catalyst were analyzed by using instruments such as sulfur carbon analyzer and inductively coupled plasma optical emission spectrometer （ICP-OES）. The results showed that the mass fraction of S and C in the sample could be well detected by the instrument when the petroleum ether was used for cleaning， the test temperature of the sulfur carbon instrument was 1 100 ℃， and the amount of catalyst sample was 0.05 g. When the calcination temperature of carbon removal pretreatment was 800 ℃， and the metal content of the catalyst was determined by microwave digestion and ICP-OES method， the results were reproducible， and the amount of Fe， Ni and V in the spent catalyst was significantly higher than that of the fresh catalyst. When the length of the catalyst was determined by mathematical segmentation and statistical method， the repeatability of the results was good， and the length of the spent catalyst was significantly shorter than that of the fresh catalyst.
