Abstract: A process for catalytic conversion of low value hydrocarbon streams to light olefins in comparatively higher yields is disclosed. Propylene is obtained in amounts higher than 20 wt. % and ethylene higher than 6 wt. %. The process is carried out in a preheated cracking reactor having a single riser and circulating an FCC catalyst. The riser is divided into three temperature zones in which different hydrocarbon feeds are introduced. An oxygenate feed is introduced in the operative top zone in the riser. Heat for the endothermic cracking is obtained by the exothermic reaction of converting the oxygenate feed into gas and / or from a regenerator in which the spent FCC catalyst is burnt.

Abstract: A process is disclosed for enhanced recovery of propylene and LPG from the fuel gas produced in Fluid catalytic cracking unit by contacting a heavier hydrocarbon feed with FCC catalyst. In the conventional process, the product mixture from FCC main column overhead comprising naphtha, LPG and fuel gas, are first condensed and gravity separated to produce unstabilized naphtha, which is subsequently used in the absorber to absorb propylene and LPG from fuel gas. However, the recovery of propylene beyond 97 wt% is difficult in this process since unstabilized naphtha already contains propylene of 5 mol% or above. In the present invention, C 4 and lighter components from unstabilized naphtha are first stripped off in a separate column to obtain a liquid fraction almost free from propylene (

Abstract translation: 公开了一种通过使较重烃进料与FCC催化剂接触，从流化床催化裂化装置产生的燃料气体中提高丙烯和LPG回收率的方法。 在常规方法中，首先将包含石脑油，液化石油气和燃料气体的FCC主塔架塔的产物混合物冷凝并重力分离以产生不稳定的石脑油，随后在吸收器中使用该燃料从燃料气体中吸收丙烯和LPG。 然而，在该方法中，丙烯的回收率超过97wt％是困难的，因为未稳定的石脑油已经含有5mol％或更高的丙烯。 在本发明中，C4和来自不稳定石脑油的较轻组分首先在单独的塔中汽提，得到几乎不含丙烯（<0.1mol％）和其它LPG组分的液体组分。 在吸收器中使用这种汽提的液体馏分，在冷却至20℃至30℃后，从燃料气体中吸收较高量的丙烯和LPG，导致丙烯的回收率提高。
