The U tubular reactor employed in this reaction practically achieves isothermal operation inside the bed, and presents good comparable results in screening new catalyst.
所采用的U型管式反应器基本实现床层内等温操作，用于筛选新型颗粒催化剂有较强的可比性。
An industrial catalyst from laboratory to commercial production, usually goes through three consecutive stages, namely, laboratory screening, pilot plant test and full-scall plant test.
催化剂从实验室研制到进行工业生产，一般要经过实验室初步筛选、中间试验、工业装置试验三个阶段。
