    Abstract: Processes for the production of olefins are disclosed, which may include: contacting a hydrocarbon mixture comprising linear butenes with an isomerization catalyst to form an isomerization product comprising 2-butenes and 1-butenes; contacting the isomerization product with a first metathesis catalyst to form a first metathesis product comprising 2-pentene and propylene, as well as any unreacted C4 olefins, and byproducts ethylene and 3-hexene; and fractionating the first metathesis product to form a C3-fraction and a C5 fraction comprising 2-pentene. The 2-pentene may then be advantageously used to produce high purity 1-butene, 3-hexene, 1-hexene, propylene, or other desired products.

    Abstract: Mixed pentenes may be converted to propylene by feeding an alcohol, linear pentenes, and isopentenes to an etherification reactor. The alcohol and isopentenes may be reacted in the etherification reactor to convert isopentenes to tertiary amyl alkyl ether, which may be separated from the linear pentenes, recovered as a linear pentene fraction. The tertiary amyl alkyl ether may be fed to a decomposition reactor to convert at least a portion of the tertiary amyl alkyl ether to alcohol and isopentenes. The alcohol and isopentenes may then be separated to recover an isopentene fraction and an alcohol fraction. The isopentene fraction is then fed to a skeletal isomerization reactor to convert at least a portion of the isopentenes to linear pentenes, the effluent from which may be recycled to the etherification reactor. Ethylene and the linear pentene fraction may then be to a metathesis reactor to produce propylene.

    Abstract translation: 混合的戊烯可以通过将醇，线性戊烯和异戊烯加入到醚化反应器中而转化成丙烯。 醇和异戊烯可以在醚化反应器中反应，以将异戊烯转化成叔戊基烷基醚，其可与线性戊烯分离，作为线性戊烯馏分回收。 叔戊基烷基醚可以进料到分解反应器中以将至少一部分叔戊基烷基醚转化为醇和异戊烯。 然后可以分离醇和异戊烯以回收异戊烯馏分和醇馏分。 然后将异戊烯级分进料到骨架异构化反应器中以将至少一部分异戊烯转化为线性戊烯，其中可将其流出物再循环至醚化反应器。 然后可以将乙烯和线性戊烯馏分转移到复分解反应器以产生丙烯。
