以双酚a、溴水和过氧化氢为原料，采用非均相催化反应技术合成四溴双酚a的新工艺。
The new preparation process of tetrabromobisphenol - a with bisphenol - a, bromine and hydrogen peroxide as raw materials by a heterogeneous catalyst reaction has been introduced in this paper.
催化转化器中CO化学反应属于气固非均相催化反应，在载体蜂窝孔内CO向催化剂固体表面的质量传输过程对CO的转化率有着重要影响。
Chemical reaction of co is a gas-solid catalytic reaction in catalytic converter. The mass transfer course of co in honeycomb holes has very important effects on co conversion ratio.
又由于这种负载型的催化剂不能较好地分散于反应介质中，影响了催化反应效率，反应时间通常比均相催化长。
In addition, usually prolonged reaction time is needed in the supported metal catalyzed reaction due to the solid catalyst can not be dispersed in the reaction medium.
