First claim
Opening claim text (preview).
The invention claimed is: 1. A method of converting carboxylic acids to aromatic hydrocarbons, the method comprising: (a) partially hydrogenating a feedstock comprising carboxylic acids in the presence of hydrogen and a hydrogenation catalyst at a hydrogenation temperature in the range of 80° C. to 350° C. a hydrogenation pressure in the range of 50 psig to 2000 psig, and a weight hourly space velocity in the range of 0.01 to 30 to produce an oxygenate mixture comprising (1) an un…
