目前我国处理量15万吨/年催化重整装置,大部份采用单铂催化剂。为了提高芳烃产率,近年来相继试制成功双金属及多金属催化剂,并投入生产。双金属和多金属重整操作压力和空速都比较低,一般压力在14～16公斤/厘米~2,空速为2时C_ 右。(单铂重整操作压力一般为25～30公斤/厘米‘,空速3时~(-1)左右),要求循环氢系统压力降尽量小,以节省压缩机功率的消耗。我厂新建15万吨/年多金属重整装置如按原设计采用轴向反应器,当空速为2时~(-1), At present, China’s handling capacity of 150,000 tons / year catalytic reformer, most of the single-platinum catalyst. In order to improve the yield of aromatic hydrocarbons, in recent years have successfully trial bimetallic and polymetallic catalysts, and put into production. Bimetallic and multimetal reforming operation pressure and airspeed are relatively low, the general pressure at 14 ~ 16 kg / cm ~ 2, airspeed at 2:00 C_ right. (Single platinum reforming operation pressure is generally 25 ~ 30 kg / cm ’, airspeed 3 ~ (-1) or so), the pressure required to recycle hydrogen system as small as possible to save the compressor power consumption. I plant a new 150,000 tons / year multi-metal reformer, such as the original design of the axial reactor, when the airspeed 2 ~ (-1),
