متن کاملNoble metal ionic catalysts.
Because of growing environmental concerns and increasingly stringent regulations governing auto emissions, new more efficient exhaust catalysts are needed to reduce the amount of pollutants released from internal combustion engines. To accomplish this goal, the major pollutants in exhaust-CO, NO(x), and unburned hydrocarbons-need to be fully converted to CO(2), N(2), and H(2)O. Most exhaust cat...
متن کاملKraft Lignin Depolymerization in an Ionic Liquid without a Catalyst
In this paper, the depolymerization of lignin was successfully achieved by the thermal treatment of kraft lignin in butyl-1,8-diazabicyclo[5.4.0]undec7-enium chloride ([DBUC4][Cl]) without a catalyst. The thermal treatment experiments were performed in an oven at 150, 200, and 250 °C for 1 h. The changes in kraft lignin structure over the course of depolymerization were characterized by gel per...
متن کاملBright Side of Lignin Depolymerization: Toward New Platform Chemicals
Lignin, a major component of lignocellulose, is the largest source of aromatic building blocks on the planet and harbors great potential to serve as starting material for the production of biobased products. Despite the initial challenges associated with the robust and irregular structure of lignin, the valorization of this intriguing aromatic biopolymer has come a long way: recently, many crea...
متن کاملBond cleavage of lignin model compounds into aromatic monomers using supported metal catalysts in supercritical water
More efficient use of lignin carbon is necessary for carbon-efficient utilization of lignocellulosic biomass. Conversion of lignin into valuable aromatic compounds requires the cleavage of C-O ether bonds and C-C bonds between lignin monomer units. The catalytic cleavage of C-O bonds is still challenging, and cleavage of C-C bonds is even more difficult. Here, we report cleavage of the aromatic...
