摘要:
A process is provided for the production of xylenes from reformate. The process is carried out by methylating under conditions effective for the methylation, the benzene/toluene present in the reformate outside the reforming loop, to produce a resulting product having a higher xylenes content that the reformate. Greater than equilibrium amounts of para-xylene can be produced by the process.
摘要:
The invention relates to removal of styrene from hydrocarbon mixtures, and more particularly, removal of styrene from hydrocarbon mixtures containing higher than equilibrium paraxylene concentrations.
摘要:
The invention is directed to a process to produce para-xylene and, optionally, ortho-xylene, including coupling two in-series xylenes separation systems with two parallel isomerization systems for energy savings and/or productivity increases.
