The adsorption pretreatment of crude oil and its effect on subsequent hydrotreating process were analyzed. Adsorptive pretreatment of crude oil over a series of the activated aluminas and activated carbons at 60 °C and 100 °C for 2 hour was conducted in a batch mode for screening adsorbents. It was found that the adsorption temperature has negligible effect on the performance of the all activated alumina in a temperature range of 60-120 °C. A significant improvement of the hydrotreatment performance can be attributed to reduction of nitrogen compounds, metal, and asphaltenes in the crude oil by the adsorption pretreatment.
