求翻译：移动床：主要特征是设有专门的再生器，反应器和再生器都是采用移动床反应器，催化剂在反应器和再生器之间不断地进行循环反应和再生，一般每 3～7d 全部催化剂再生一遍。是什么意思？

Moving Bed: The main feature is equipped with a special regenerator, reactor and regenerator are based on the moving bed reactor, the catalyst in the reactor and regenerator loop continuously between the reaction and regeneration, usually every 3 ~ 7d all catalysts recycled again.

Mobile bed: main feature is that there are dedicated server that is renewable, reactors and renewable sources are used in mobile bed and fluidized catalytic reactors and renewable sources, and continuous cycle between server response and renewable sources in general, every 3 to 7 D catalyst all rene

Moves the bed: The main characteristic is equipped with the special regenerator, the reactor and the regenerator all is uses the motion bed reactor, the catalyst carries on the circular reactions unceasingly between the reactor and the regenerator and regenerates, general each 3~7d complete catalyst

Moving bed: the main characteristic is the regenerator dedicated, reactor and regenerator is using moving bed reactor, catalyst in the reactor and regenerator constantly circulating between reaction and regeneration, General catalyst regeneration per 3~7d all over again.
