催化剂

• The setting of mechanical specifications for catalysts should take into consideration the needs of the user .
  催化剂的机械测试技术规范的制定应考虑到用户的需要。
• On vaporization it reduces the bulk density of upflowing mixture and promotes the circulation of catalyst .
  在汽化时使向上流动的混合物的松密度减少，并促使催化剂循环。
• The swiss chemists think that the catalyst first draws the sensitizer to its surface and holds it there .
  瑞士化学家认为，催化剂首先把敏化剂吸到它的表面并附着在那里。
• There are inherent difficulties in selecting any method as a standard for catalytic surface area determinations .
  要选定一种测定催化剂表面积的标准方法具有其特有的困难。
• A second more severe water test is to place the catalyst in boiling water and observe for any disintegration .
  第二个更苛刻的泡水试验是将催化剂放在开水中检查有没有开裂。
• In the thermal reactor it promotes corrosion, and in the catalystic reactor it tends to poison the catalyst .
  在热反应器中，它促进腐蚀，在催化反应器中，它能使催化剂中毒。
• We would like to measure the intrinsic selectivity behavior of a catalyst independent of any potential disguises .
  我们很想去掉任何可能的假象以测定催化剂固有选择性的可能。
• The catalyst vendors came out with a catalyst incorporating a low surface area, high purity alumina carrier .
  催化剂出售商供应了一种具有表面积小，纯度高的氧化铝载体催化剂。
• In this manner a set of tests has evolved to the satisfaction of vendor and catalyst user for each catalyst .
  用这种方式对每种催化剂建立一套催化剂卖主和用户都满意的测试方法。
