sintering period

Sintering process and Mixed combination process developed based on Chinese bauxite characteristics and a given historical period are facing sharp international competitive and lack of reserve strength in development.

以我国铝土矿特点在特定历史条件下发展起来的烧结法和混联法氧化铝工业面临激烈国际竞争，发展后劲不足。

During reaction period, the partial reduction of CeO_2 stimulates the redispersion between Ce and Cu, strengthens the interreaction of Ce and Cu and depresses the sintering of the Ce and Cu crystallite, thus promotes the heat stability of the catalyst.

在反应过程中由于CeO2部分还原，促进了铈与铜之间的重新分散，加强了二者间的相互作用，抑制铜晶烧结，从而提高了催化剂的热稳定性。
