According to the low yield of propylene existing in gas fractionation device due to higher C2 content in LPG, the factors affecting on LPG quality in the absorbing-stabilizing system were analyzed. Some technics such as optimization of operating condition and energy-efficient process were adopted to intensify the separation effect, offering the advice with lower C2 content (no more than 0.1%χ) in...
This research reviews the effects of the single component, the mixed oxides and the mesoporous materials on catalyst. Titanium dioxide and zirconium dioxide as single component support show higher activity than alumina in hydrodesulfurization, but their specific surface area need be increased further. Compared with the single component, the mixed oxides with higher specific surface area and strength...
