Abstract: The processing and properties of porous silicon carbide were studied. The dextrin was used as pore-making agent and binder. The porous silicon carbide with a porosity
from 27% to 70% was synthesized by adjusting the content of dextrin and at the same time the pore size and distribution of the specimen can be effectively controlled.
XRD and SEM were carried out to characterize phases and microstructure of the specimen. The isomerization behavior of molybdenum oxycarbide supported on such material was studied.
The selectivity of it is 70% for dodecane which is higher level compared to other porous materials. But the activity is only 20%. The reasons for this need to be further investigated.
