Abstract
Official abstract text for this publication.
Technologies to convert biomass to liquid hydrocarbon fuels are currently being developed to decrease our carbon footprint and increase use of renewable fuels. Since sugars/sugar derivatives from biomass have high oxygen content and low hydrogen content, coke becomes an issue during zeolite upgrading to liquid hydrocarbon fuels. A self-sustainable process was designed to reduce the coke by co-feeding sugars/sugar derivatives with the paraffin products from hydrogenation of sugars/sugar derivatives. Paraffins without complete conversion result in products with less aromatics and relatively low density compared with the products directly from zeolite upgrading. Thus, the process is more economically favorable.
First claim
Opening claim text (preview).
What is claimed is: 1. A system for producing gasoline from biomass comprising: a) a feedstock stream comprising at least one member selected from the group consisting of sugars, sugar derivatives, polyols and carbohydrates, b) a hydrotreater configured to convert a first portion of said feedstock stream to paraffins in the presence of hydrogen and a hydrotreating catalyst, c) a catalytic upgrader comprising a zeolite catalyst and configured to receive and convert a second por…
