Abstract
Official abstract text for this publication.
A xylan-containing feed is contacted, in the first reactor essentially operated at plug flow, with an aqueous solution of an acid at a temperature in the range from equal to or more than 140° C. to equal to or less than 210° C. to produce an intermediate product. Then, the intermediate product is contacted, in the second reactor which comprises a continuously stirred tank reactor, with an aqueous solution of an acid at a temperature in the range from more than 130° C. to equal to or less than 200° C. to produce a final product.
First claim
Opening claim text (preview).
What is claimed is: 1. A process for the conversion of a xylan-containing feed comprising: a) contacting, in a first reactor essentially operated at plug flow, the xylan-containing feed with an aqueous solution of an acid at a temperature in the range from equal to or more than 140° C. to equal to or less than 210° C. under conditions to produce an undercooked intermediate product; and b) contacting, in a second reactor which comprises a continuously stirred tank reactor, the un…
