Reactors having varying cross-section, methods of making same, and methods of conducting reactions with varying local contact time

摘要

The present invention provides methods of conducting chemical reactions in a reaction channel that has an varying cross-sectional area such that a chemical reactant or reactants experience varying local contact time as the reactant(s) flow through the channel. The invention also provides reactors having reaction channels with varying cross-sectional areas. In a particularly preferred embodiment, the reaction channel section has a trapezoidal shape that becomes broader from the inlet toward the outlet.
