Disclosed herein is a process for upgrading a raffinate butene (C4 Raffinate) stream to propylene which can produce polymer grade propylene (PGP) by a metathesis process, without consuming fresh ethylene as a feedstock. By recycling ethylene byproduct in the metathesis equilibrium, propylene selectivity can be further improved without negatively impacting butene conversion. Additionally, upon PGP separation, this technology can provide an effluent acceptable for alkylate production by achieving a balanced butene conversion and heavies coproduction. The disclosed process is a relatively low temperature process which can be deployed as a drop-in option for conventional ethylene/butene metathesis unit and provide additional flexibility to existing operations to balance the supply and demand of C2-C4 light olefins.

Process for converting raffinate butenes to propylene

A process of producing allyl alcohol by reacting glycerin with ReO&#x2014;AlOin the presence of gamma-valerolactone (GVL) in a reactor is described. More specifically, a process to produce allyl alcohol, comprising the step of: a) reacting glycerin with ReO&#x2014;AlOin the presence of an inert solvent, GVL, in a reactor, and b) collecting the product comprising allyl alcohol.

Glycerin-only reaction for allyl alcohol production

A process for producing furan dicarboxylic acid or an ester thereof from a feedstock comprising hydroxymethyl furfural (HMF) and humins is disclosed. Humins are a byproduct from reactions forming HMF from sugars and are typically removed from the HMF prior to any further processing. A humins-containing HMF feedstock is utilized to produce furan dicarboxylic acids and ester substantially free from humins.

Processes for preparing 2,5-furandicarboxylic acid and esters thereof

The present disclosure relates to a method including subjecting an organic stream comprising at least one oxygenate to hydrotreatment, whereby a hydrotreatment product comprising ethylbenzene is produced, wherein the organic stream is a product of a process for the production of propylene oxide; and separating an ethylbenzene product stream from the hydrotreatment product, to yield a residual stream.

By-product stream upgrading in a propylene oxide/styrene coproduction process

Furfural is produced by contacting a feedstock solution containing Csugar and/or Csugar with a solid acid catalyst using reactive distillation. Both high yield and high conversion are obtained, without production of insoluble char in the reaction vessel. Degradation of furfural is minimized by its low residence time in contact with the solid acid catalyst. Higher catalyst lifetime can be achieved because the catalyst is continually washed with the refluxing aqueous solution and not sitting in high-boiling byproducts like humins, which are known to be deleterious to catalyst lifetime.
