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.
