Negative observed activation enthalpies obtained in hydride transfer reactions and in Diels Alder reactions indicate that CT complexes act as true intermediates in these react.

Based on the Daqing vacuum gas oil’s reaction on an acid Y zeolite catalyst, hydride transfer and hydrogen transfer were distinguished as two different reaction stages during the catalytic cracking.

The theoretical studies on a series of α-hydrogen shift reactions between the alkylidene and alky-lidyne organometallic molybdenum complexes R3R4Mo(=CH)(CHR1R2) and R3R4Mo(=CH2)(=CR1R2) were carried out with the density functional theory B3LYP method.

The theoretical studies on a series of α-hydrogen shift reactions of the organometallic tungsten complexes were carried out with the density functional theory B3LYP method.

Effects of hydrogen transfer reaction on the olefin content of gasoline in FCC process;

Through the study of associated technical information, the impact of modification elements on the zeolite acidity, zeolite pore structure and distribution, Si-Al ratio, activity and selectivity of hydrogen transfer reaction are analyzed.

The controllability of cracking reaction was realized by utilizing the hydrogen transfer reaction to terminate the cracking reaction, and thus the functions of two reaction zones were extended to provide diversified modes of production according to MIP process technology.

Secondary reaction in gasoline upgrading process such as hydrogen transfer, isomerization, cyclization, oligomerization as well as the ratio between two kinds of hydrogen transfer reactions have been quantitatively calculated with the lumping dynamic model.
