The Intermetallic Catalysts for Oxidative Esterification of Methacrolein to Methyl Methacrylate
methyl methacrylate Pd-Pb catalyst oxidative esterification
2009/11/13
A series of supported intermetallic Pb-Pb catalysts were prepared with the impregnation method by changing the support (silica, molecular sieve or g-alumina ) and the pore size. The chemical states of...
EFFECT OF CHAR LAYER ON TRANSIENT THERMAL OXIDATIVE DEGRADATION OF POLYETHYLENE
thermal oxidative degradation polyethylene reflectivity
2009/10/14
A transient one dimensional model has been presented to simulate degradation and gasification of polyethylene, in early stage of fire growth. In the present model effect of oxygen on degradation and r...
