Honeycomb structure

摘要

A honeycomb structure includes at least one honeycomb unit including zeolite; an inorganic binder; and cell walls defining cells extending along the longitudinal direction of the honeycomb unit. The honeycomb unit has one or more peak values of the log differential pore volume in a pore diameter range between 0.006 and 0.06 µm and has one or more peak values of the log differential pore volume in a pore diameter range greater than 0.06 µm and less than or equal to 1 µm. The volume of pores having diameters in a range plus or minus 0.03 µm of a pore diameter corresponding to the highest peak value in the pore diameter range greater than 0.06 µm and less than or equal to 1 µm, amounts to 60% to 95% of the volume of pores having diameters greater than 0.06 µm and less than or equal to 1 µm.
