The application results show that in comparison with the base catalyst, the yield of dry gas and slurry was reduced, while the total liquid yield, gasoline yield and LPG yield increased by 1.34, 5.05 and 1.43 percentage points,respectively. The properties of the products showed no significant change while the anti-abrasion strength of the catalyst was relatively high. Based on the mid-term calibration test, the summary calibration test and the daily statistics of long term industrial application practice, the HSC catalyst features a strong conversion ability of heavy oil, a high gasoline yield, a satisfactory product distribution and a good selectivity.展开更多

The same method was used to investigate the presence of elements ranging from silicon to lead in different soils samples and seaweed collected upstream from the site of Safi-El Jadida industrial zone, inside lands and downstream of it, in the entrance of the Casablanca region. This study allows us to highlight the influence of activities of this industrial zone on the neighbouring areas the site.展开更多
