| Abstract: | The optimization of various amount of hydrogenation catalyst has been studied by pyrolysis hydrogenation gas chromatography in the presence of 10wt% Pt on 80/100 mesh Diasolid H as a sample of high density Polyethylene(HDPE).The catalyst caoacity range is from 0.00mg to 94.00mg.As a result,it was found that≥54.00mg hydrogenation catalyst is to meet the needs of the pyrolysis hydrogenation technology during a sample amount is controlled≤80μg. |
