Abstract
The present disclosure relates to processes for production of alkene products from their alkene precursors, such as 3-hydroxyacid and alcohols, via either (1) high temperature reactive distillation with steam contact at optimal pH, (2) solvent extraction and Mulzer dehydration, (3) solid phase adsorption, desorption into an organic solvent and catalytic reaction and (4) high temperature reactive distillation with steam contact at optimal pH followed by catalytic conversion.
Claims77
A method for preparing an alkene product comprising,
- providing a 3-hydroxyacid precursor or an alcohol precursor;
- using high temperature reactive distillation with steam contact;
- and
- forming at least one alkene product.
A method producing an alkene product comprising:
- (a) extracting fermentation broth to produce an extracted alkene precursor mixture;
- and
- (b) implementing a dehydration reaction to produce from the extracted alkene precursor mixture an alkene product mixture comprising the alkene product.
A method of producing an alkene product comprising:
- (a) contacting a fermentation broth and a solid phase adsorbent;
- (b) desorbing at least one alkene precursor from the solid phase adsorbent;
- (c) distilling the desorbed alkene precursor;
- and
- (d) producing an alkene product mixture comprising the alkene product by reacting the distilled alkene precursor in a catalytic reactor.
A method for preparing an alkene product from a 3-hydroxyacid precursor or an alcohol precursor using high temperature reactive distillation with steam contact and catalytic reaction.
