Title:
INTEGRATED PROCESS TO SELECTIVELY CONVERT RENEWABLE ISOBUTANOL TO P-XYLENE
Document Type and Number:
Japanese Patent JP2015193647
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for preparing renewable and relatively high purity p-xylene from biomass.SOLUTION: In one embodiment, for example, biomass treated to provide a fermentation feedstock is fermented with a microorganism capable of producing a Calcohol such as isobutanol, then sequentially dehydrating the isobutanol in the presence of a dehydration catalyst to provide a Calkene such as isobutylene, dimerizing the Calkene to form one or more Calkenes such as 2,4,4-trimethylpentenes or 2,5-dimethylhexene, then dehydrocyclizing the Calkenes in the presence of a dehydrocyclization catalyst to selectively form renewable p-xylene in high overall yield. The p-xylene can then be oxidized to form terephthalic acid or terephthalic acid esters.
