The ZRP zeolite with high n(SiO2)/n(Al2O3) possessed more strong acid so that the conversion of olefin and the selectivity of light olefin were both increased. But the selectivity of butylene was higher than that of propylene.
INVESTIGATION OF ALKENE OLIGOMERIZATION CATALYST SERIES DERIVED FROM COMPLEX OF FERRIC SULFATE AND NICKEL SULFATE Ⅰ.A Study on Catalytic Behavior of Fe (2/3) x Ni 1- x SO 4 P 2O 5/ γ Al 2O 3 for Propene
The experimental results show that the yields of cracking gases, gasolines, light oils and cokes, the conversions of heavy oils and the contents of various constituents of cracking gases, especially C_3~+ and C_4~= alkenes increase obviously, while the yields of heavier oils and diesel oils decrease remarkably with the increasing of the ratio of catalyst/heavy oil under the given test conditions.
Design and synthesis of structurally well-defined functional polypropylenes via transition metal-mediated olefin polymerization
This paper summarizes our recent effort to access structurally well-defined functional polypropylenes via transition metal-mediated olefin polymerization.
The separations of olefin/paraffin, aromatic/aliphatic hydrocarbons or olefin isomers using ionic liquids instead of volatile solvents have interested many researchers.
Quantitative determination of olefin oxide, chlorohydrin, and cyclocarbonate in the presence of each other
A procedure was developed for the quantitative determination of olefin oxide, chlorohydrin, and cyclocarbonate simultaneously present in the reaction mixture of the synthesis of cyclocarbonate from olefin oxide and CO2.
Continuous reaction performances of benzene alkylation with long chain olefins catalyzed by ionic liquid
Based on a compulsive mixing-reacting-separating-recycling small experimental setup,the continuous reaction performances of benzene alkylation with long chain olefins catalyzed by [BMIM]Cl-AlCl3 ionic liquid were investigated.
The refined industrial olefins as raw material could meet with the requirements of continuous alkylation.
The influences of impurities such as di-olefins and non-benzene aromatics on the catalytic activity and stability should be studied further.
Study on reformulation of fluid catalytic cracking gasoline and increasing production of light olefins
The liquid phase is mainly composed of alkane and alkene (C5-C29), and the gas phase is dominantly HCS and H2.
The Mechanism of Cp2ZrCl2-Catalyzed Alkene Cycloalumination with Triethylaluminum to Give Alumacyclopentanes
Meanwhile, much lower K values (～ 2 to 3) were observed for alkane-alkene pairs, in spite of a rather high difference in the ionization potentials (ca.
This effect was explained by the conformation dispersion and distribution of environment configurations of ionized molecules for the alkane-alkene pairs.
The results of studying homogeneous and heterogeneous catalytic systems for alkene arylation (the Heck reaction) illustrate the influence of the main catalytic cycle on the efficiency of the formation and regeneration of catalytically active species.
