摘要：

Pores for thought: Chemical liquid deposition of silica onto ZSM-5 catalysts led to smaller pore openings that resulted in >90 % selectivity for p-xylene over the other xylenes in the catalytic fast pyrolysis of furan and 2-methylfuran (see scheme). The p-xylene selectivity increased from 51 % with gallium spray-dried ZSM-5 to 72 % with a pore-mouth-modified catalyst in the pyrolysis of pine wood. Copyright © 2012 WILEY-VCH Verlag GmbH & Co.
