| Abstract: | The analysis of the shortened service life of non-aromatics hydrotreating catalysts concluded that the main culprit of catalyst deactivation was coke deposit on the catalysts.The following countermeasures have been taken on the basis of study on the factors affecting the coke on the catalysts:(1) the inlet temperature of reactor was adjusted;(2) feedstock dehydration was improved.In addition,the appropriate distribution of reactor temperature rise has changed the situation that the hydrotreating reaction ma... |
