摘要： Processes for the production of high purity alpha olefins from a mixture of olefins are disclosed. The processes may include: contacting propylene and a hydrocarbon mixture comprising a mixture of olefins having a carbon number n with a first metathesis catalyst to form a metathesis product comprising a beta-olefin having a carbon number n+1, an alpha-olefin having a carbon number n−1, as well as any unreacted propylene and olefins having a carbon number n. The metathesis product may be fractionated to recover a fraction comprising the beta-olefin having a carbon number n+1. Ethylene and the fraction comprising the beta-olefin having a carbon number n+1 may then be contacted with a second metathesis catalyst to form a second metathesis product comprising an alpha-olefin having a carbon number n and propylene, which may be fractionated to form a propylene fraction and a fraction comprising the alpha olefin having a carbon number n.

摘要： 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.
