Abstract

Baker Hughes Inc. (BHI) announces use of novel composite materials based on carbon nanotubes, multiwall carbon nanotubes and/or 2D grapheme and functionalized grapheme materials functionalized with MgO and CaO nanoparticles to react with naphthenic acids in crude oil or biofuels and biocrude in a process and thus reduce their corrosion activity significantly.

Novel Composite Materials for High Temperature Removal of Naphthenic Acid Corrosion

Baker Hughes Inc. (BHI) announces use of novel composite materials based on carbon nanotubes, multiwall carbon nanotubes and/or 2D grapheme and functionalized grapheme materials functionalized with MgO and CaO nanoparticles to react with naphthenic acids in crude oil or biofuels and biocrude in a process and thus reduce their corrosion activity significantly.

BHI claims the following application benefits:

·                Carbon nanotubes, multiwall carbon nanotubes and/or 2D grapheme structures are excellent supports for decarboxylation catalyst such as MgO and CaO.

·                Use of carbon nanotubes, multiwall carbon nanotubes and/or 2D grapheme allow high concentrations of well dispersed catalyst to be added to hydrocarbon or biofuel and biocrude streams containing carboxylic acids. Better distribution and higher catalyst levels improve efficiency of the decarboxylation reactions that reduce total acid number (TAN) of the material to which it is applied. .

·                TAN reduction can be accomplished in petroleum or bio based crude oils, resids and distillates obtained from these feedstock in a refining process.

·                A larger reduction of TAN can be accomplished under conditions less severe than can be accomplished with other forms of MgO or CaO. The conditions include lower temperatures and shorter duration of contact than are possible with other forms of decarboxylation aids.

·                The composites have good high temperatur...
