Two kinds of cycloalkoxy silane compounds were synthesized and used as the internal electron donors(IEDs) of supported Ziegler-Natta catalyst for ethylene polym
Catalytic pyrolysis process(CPP)producing ethylene and propylene from paraffin base atmospheric residue was developed by RIPP and its first in the world unit wa
The doping effects of Sm in La0.67Ca0.33MnO3 oxide were studied. The results show that with increasing the doping amount of Sm the phase transition temperature
This paper relates to highly dispersed supported Pd/MWCNTs and Pd/α-Al 2 O 3 catalysts prepared by biological reduction method. The physico-chemical properties
