美国Ｐｈｉｌｌｉｐｓ石油公司开发了ＳＺｏｒｂ汽油吸附脱硫新工艺 ,该工艺可用于ＦＣＣ汽油脱硫 ,工艺过程中使用少量氮气 ,主要用于防止焦炭沉积在ＳＺｏｒｂ吸附剂上。氢气和汽油的混合物流在进料加热炉中蒸发 ,注入膨胀的流化床反应器底部 ,物流通过床层 ,与吸附剂接触 , Phillips Petroleum Company of the United States has developed a new SZorb gasoline adsorption desulfurization process, which can be used for FCC gasoline desulfurization, using a small amount of nitrogen in the process, is mainly used to prevent coke deposition on the SZorb adsorbent. The combined stream of hydrogen and gasoline is vaporized in a feed furnace, injected into the bottom of the expanded fluidized bed reactor, the stream is passed through the bed, contacted with the adsorbent,
