ZSM-5 nanowires assembly supported on medium surface area foam beta-SiC composite with nanoscopic surface properties.

The present study reports the synthesis of supported zeolite with nanoscopic size on the SiC-based composite combining nanoscopic properties, i.e., SiC nanofibers, and macroscopic shaping, i.

Efficient synthesis of dimethyl ether over HZSM-5 supported on medium-surface-area beta-SiC foam.

In this study, we aimed to produce a highly selective and stable catalyst for the production of dimethyl ether by methanol dehydration. The activities were compared of different active phases of the employed system, zeolite HZSM-5 or gamma-alumina, supported on silicon carbide as foam, and it was found that the supported zeolite catalysts are more active than and as selective as the alumina-based catalysts. The as-prepared zeolite/SiC composites reveal good stability in long-term tests in the presence or absence of steam.
