| 摘要 |
<p>The invention concerns a method for catalytic chemical reaction being normally carried out at high temperature, which consists in providing a solid catalyst comprising an active metal phase, and a refractory catalytic support based on silicon nitride whereon the active phase is deposited, the catalytic support comprising mainly alpha silicon nitride, preferably in substantially non-porous state, and the reaction temperature being controlled at a value ranging between 200 °C and 600 °C.</p> |
