 th the catalyst and the reactor should be close to perfect. Although popul
 ar for good reasons (high catalyst loading\, convenient\, low cost) random
  packed beds do not fulfil this requirement. Structured catalysts and reac
 tors offer high precision in catalysis\, from the scale of the catalyst sp
 ecies up to the scale of the reactor. Monoliths are the prime example beca
 use of their high popularity in several high-profile applications.\n\nAs a
  rule\, the flow in monoliths is laminar\, and\, as a consequence\, they a
 re associated with high efficiency and reduced chaotic characteristics. Un
 der most conditions\, in multiphase systems Taylor flow (segmented flow) p
 revails\, associated with high rates of mass transfer notwithstanding low 
 energy consumption\, but under other conditions the film flow regime can b
 e realized either in cocurrent or countercurrent flow of gas and liquid st
 reams.\n\nMonoliths offer freedom of design of reactor configurations. Exa
 mples are loop reactors for strong exo- and endothermal reactions\, rotati
 ng monoliths for air conditioning and monoliths with fast radial mass tran
 sport suitable for highly endo/exothermal gas phase reactions.\n\nIn appli
 cations in which high gas flows have to be accommodated\, structured react
 ors are the state-of-the-art reactor bodies in many cases\, exemplified by
  automobile exhaust abatement monolithic reactors.\n\nApplications in liqu
 id-phase and gas-liquid-phases processes in structured reactors are scarce
 \, but they are applied in commercial production processes. Well-known app
 lications are in the the reduction step in the production of hydrogen pero
 xide\, in several plants based on catalytic distillation and\, last but no
 t least\, in (challenging) production processes in fine chemistry.\n\n*Bio
 graphy:* Jacob A. Moulijn (Google Scholar) is an Emeritus Professor of Che
 mical Engineering at the Delft University of Technology (1990-2007) and at
  the University of Amsterdam (1986-1990). He was a well-recognised visitin
 g professor at several universities in USA\, UK\, China\, Belgium\, Singap
 ore and India. He was active in China for the United Nations – World Ban
 k. Back to 1972\, he received his PhD on adsorption and diffusion phenomen
 a in porous materials and packed beds from University of Amsterdam. His re
 search interests include catalysis engineering\, catalytic reactors\, zeol
 itic membranes\, kinetics\, mass transfer\, multiphase monolithic reactors
 \, catalyst testing\, petroleum conversion (Hydroteating\, FCC\, Fischer-T
 ropsch)\, exhaust gas catalysis (soot from diesel engines\, N2O removal\, 
 NO\nabatement\, H2S removal\, CFC conversion)\, selective hydrogenation\, 
 selective oxidation\, photo- and electrocatalysis. He is a (co-) author of
  over 750 technical papers\, co-author of two books\, editor of seven book
 s\, holder of several patents (reactor design\, zeolitic membranes\, catal
 yst development). In addition\, he is a consultant in the field of biomass
  conversion and a co-founder of a start-up – Delft IMP.
