A process of purifying acetic acid is provided. The process includes feeding a stream of acetic acid into a distillation column and distilling acetic acid in the presence of an oxidizing agent in the distillation column, to oxidize oxidizable impurities in the acetic acid, wherein the oxidizing agent is an oxidant capable of cleaving C&#x2550;C bonds. The process further includes removing a distilled acetic acid stream from the distillation column. Further processes for purifying acetic acid and systems for purifying acetic acid are also provided.

Method for generating a purified catalyst

A process of decomposing a biomass derivative to produce a gaseous product and then introducing the gaseous product into a steam reformer.

Method for producing renewable hydrogen from biomass derivatives using steam reforming technology

A method of making a heterogenously supported catalyst useful in dimerization, oligomerization or polymerization is provided in which a catalyst precursor containing a metal and an aromatic group are alkylated onto an oligomeric support having at least one terminal unsaturated group by Friedel Crafts alkylation.

Heterogeneous supports for homogeneous catalysts

Methods and apparatus relate to treating hydrocarbons recovered with steam condensate from a formation. The treating removes particulates from the hydrocarbons by addition of a flocculant to produced fluids containing the hydrocarbons and an aqueous phase with the condensate. The flocculant causes the particulates suspended in the hydrocarbons to agglomerate and be transferred to the aqueous phase, which is then separated from the hydrocarbons.

Processing oil from steam assisted production
