Mixed butene streams containing butene-1 and isobutylene and optionally butene-2 are hydroformylated under conditions that hydroformylates all the monomers to yield a mixture of valeraldehydes. Higher temperatures and/or longer residence times and/or higher partial pressure of carbon monoxide than in conventional processes are used to ensure hydroformylation of all the monomers.

Hydroformylation of butenes

Mixed butene streams containing butene-1 and isobutylene and optionally butene-2 are hydroformylated under conditions that hydroformylates all the monomers to yield a mixture of valeraldehydes.

Processes related to the hydroformylation of butenes

The invention relates to the use of isobutene-containing olefin feedstock in oligomerization reactions, particularly in the production of octenes as feedstock for the manufacture of plasticizer alcohols, the process comprising contacting a feed comprising isobutene with a molecular sieve at a temperature in excess of 240&#xb0; C. to produce a product low in triple-branched octenes.

Oligomerization of isobutene-containing feedstocks

In a process for producing a hydrocarbon composition, a feed comprising at least one Cto Colefin and an olefinic recycle stream rich in C&#x2212; hydrocarbons is contacted with a crystalline molecular sieve catalyst having an average crystal size no greater than 0.05 micron and an alpha value between about 100 and about 600 in at least one reaction zone under olefin oligomerization conditions including an inlet temperature between about 150&#xb0; C. and about 350&#xb0; C., a pressure of at least 2,860 kPa and a recycle to feed weight ratio of about 0.1 to about 3.0. The contacting produces an oligomerization effluent stream, which is separated into at least a hydrocarbon product stream rich in C+ hydrocarbons and the olefinic recycle stream.

Olefin oligomerization to produce hydrocarbon compositions useful as fuels

Herein are fluid compositions and methods of making such compositions, wherein the compositions comprise Cto Cesters of a mixture of C&#x2013;Cbranched carboxylic acids and C&#x2013;Clinear carboxylic acids.

Ester-containing fluid compositions

Disclosed are ester-containing fluid compositions, methods of making such compositions, and methods of using such compositions. The fluid compositions comprise a mix of branched and linear ester compounds, and the fluid compositions are characterized by certain performance limitations. The preferred method of making the fluid compositions enables the ester mix to be made in a one step process with little finishing required to obtain desirable performance characteristics.

The present invention relates to processes for making a reaction product comprising trimethylpentene(s) which comprises contacting a Colefinic feedstock containing isobutene and n-butene(s) with a catalyst comprising zeolite beta under conditions allowing selective dimerization of isobutene to trimethylpentene(s). It also relates to the products obtained by these processes.

Process for the selective dimerization of isobutene

Disclosed is an olefin containing stream from an oxygenate to olefin process, and a process for making olefin dimer and oligomer product from the olefin containing stream using a nickel based oligomerization catalyst. The dimer/oligomer product is optionally converted to hydroformylated product. The olefin containing stream that is used to make the higher olefin product has low levels of impurities including nitrogen, sulfur and/or chlorine.
