摘要
由于催化裂化投资和操作费用低 ,原料适应性强 ,转化率高 ,自 194 2年第一套工业化流化催化裂化装置运转以来 ,它已发展成为炼油厂中的核心加工工艺 ,是重油轻质化的主要手段之一。催化裂化产品是主要的运输燃料调合组分。在世界范围内 ,FCC汽油占总汽油产量的 2 5 %～ 80 % ,FCC柴油占总柴油量的 10 %～30 % ,而且是仅次于蒸汽裂解制取丙烯的又一大生产装置。面对日益严格的环保法规的要求 ,通过装置改造和与其它上下游工艺结合 (如进料加氢 ,产品后处理等 ) ,催化裂化能以合适的费用生产合适的产品。即使从更长远的目标看 。
Since the first commercial fluid catalytic cracking unit was put into operation in 1942, FCC has become a leading processing technology and one of the residue upgrading technologies in refinery due to its low operating cost, good adaptability to different feedstocks and high conversion for light products. As one of the main blending components of transportation fuel, FCC gasoline takes 25%-80% of the total gasoline pool and FCC diesel 10%-30% of the total diesel pool in the world. FCC ranks the second place to the steam cracker to produce propylene. To meet the increasing stringent environmental regulations, FCCU can produce superior products at proper cost through revamping and integrating with other upper stream or down stream processes (such as feedstock hydrotreating, product post-treating). From a long-term point of view, the hydrosaturated FCC gasoline will also become a fuel component of fuel cells.
