Abstract
Official abstract text for this publication.
The present invention provides methods, reactor systems, and catalysts for increasing the yield of aromatic hydrocarbons produced while converting alkanols to hydrocarbons. The invention includes methods of using catalysts to increase the yield of benzene, toluene, and mixed xylenes in the hydrocarbon product.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of converting alkanols to aromatic hydrocarbons comprising: partially dehydrogenating a C 1 -C 6 alkanol feedstock in the presence of a dehydrogenation catalyst at an effective dehydrogenation temperature and dehydrogenation pressure to produce hydrogen and a mixture of oxygenate components comprising (a) unreacted C 1 -C 6 alkanol and (b) a carboxylic acid, an aldehyde, an ester or any combination thereof; wherein at least a portion of the…
