During the oligomerization of ethylene over heterogeneous catalysts, the production of α-olefins may be lowered because of an accompanying deactivation of catalyst resulting from strong adsorption of products, by isomerization or by a tendency to co

A novel slurry reactor was used to investigate the copolymerization behavior of ethylene and 1-butene in the presence of 1 wt % Cr on Davison silica (Phillips-type) catalyst over the temperature range of 0–50°C, space velocity of about 0.0051 [m3

The reaction rates for the hydrolysis of CS2 on either alumina (Kaiser 201) or titania (CRS 31) were measured at 150 kPa and from 270 to 330°C using a laboratory Berty reactor over ranges of water concentration (2–12 mol%) and CS2 concentration (0

Prior studies on the adsorption of SO 2 on γ-alumina are not particularly revealing about the SO 2 -alumina surface interactions. Chemisorbed SO 2 on alumina was examined using a TPD-MS approach. The use of S 18 O 2 clearly demonstrated that both mo

Industrial alumina- and titania-based catalysts were tested for CS2 hydrolysis in a Berty reactor. Activated bauxite is the most active catalyst below 290°C and titanium oxide above 290°C. TGA experiments examining water desorption from 50°C to 55

Ethylene polymerization was carried out over both porous and non-porous 5 wt% Cr/silica catalysts in a slurry reactor. The polymerization was stopped at selected times to obtain samples for SEM and TEM characterization. Despite the different physical

High temperature treatment under vacuum or in a pure N2 atmosphere can be used instead of a reduction step to activate Cr/SiO2 catalysts used for ethylene polymerization. After this procedure, the Cr species active over a range of temperature has bee
