摘要: A process for the oligomerization of propylene is disclosed wherein MCM-22 zeolite prepared as a distillation structure is used in a reaction distillation zone under conditions of temperature and pressure to concurrently react the propylene to produce oligomers thereof and separate the oligomer products from unreacted propylene by fractional distillation in a distillation column reactor. Compared to the prior art tubular or plug flow reactors, lower temperatures and pressures are used to produce higher conversions and selectivities to preferred isomeric forms.

摘要: A process for the oligomerization of propylene is disclosed wherein a tungstated zirconia catalyst prepared as a distillation structure is used in a reaction distillation zone under conditions of temperature and pressure to concurrently react the propylene to produce oligomers thereof and separate the oligomer products from unreacted propylene by fractional distillation in a distillation column reactor. Compared to the prior art tubular or plug flow reactors, lower temperatures and pressures are used to produce higher conversions and selectivities to preferred isomeric forms useful for preparing neo acids.

摘要: A process for the reduction of naphthalene in process streams containing alkylaromatic solvents. Naphthalene is contacted with alkylbenzenes in a distillation column reactor in the presence of transalkylation catalyst to produce alkylnaphthalenes which are concurrently separated by fractional distillation as bottoms and the alkylbenzenes are separated as overheads.

摘要: Alkenes, such as normal butenes in a mixed C4 stream are oligomerized, preferably to dimers, which are dimerized in a distillation column reactor over ZSM-57 zeolite catalyst at high conversions and high selectivity to octenes. Prior to oligomerization the mixed C4 stream is pretreated to remove dimethyl ether, butadienes and sulfur compounds.
