| titleOfInvention | Oxygen conversion to propylene using selective hydrogenation of heavy olefin recycle stream |
| abstract | Average cyclic propylene selectivity from oxygenate to propylene (OTP) using one or more fixed or mobile phases of a dual function oxygenate conversion catalyst with recycling of one or more C 4 + olefin rich fractions is detrimental to harmful such as dienes and acetylene hydrocarbons Substantially improved by using selective hydrogenation techniques for this C 4 + olefin rich recycle stream to substantially remove the coke precursor. This hydrotreatment step helps to maintain the accumulation of harmful coke deposition on the catalyst at levels that do not substantially degrade dual function catalytic activity, oxygenate conversion and propylene selectivity, thereby substantially improving the propylene average circulation yield. have. Compared to prior art systems that do not use a hydrotreatment step for the C 4 + olefin rich recycle stream, the propylene average circulation yield improvement possible by the present invention is on the order of 1.5 to 5.5% by weight or more.n n n n Propylene, oxygenate, dual function catalyst |
