摘要:
A flow reactor has a module having a process fluid passage with an interior surface, a portion of the passage including a cross section along the portion having a cross-sectional shape, and a cross-sectional area with multiple minima along the passage. The cross-sectional shape varies continually along the portion and the interior surface of the portion includes either no pairs of opposing flat parallel sides or only pairs of opposing flat parallel sides which extend for a length of no more than 4 times a distance between said opposing flat parallel sides along the portion and the portion contains a plurality of obstacles distributed along the portion.

A flow reactor fluidic module (12) includes a reactant fluid module (20) having an internal process fluid passage (22) and a first major planar outer surface (24a) and a thermal resistance R between the internal process fluid passage (22) and the first major planar surface (24); a thermal control fluid module (30) having an internal thermal control fluid passage (32) and a second major planar outer surface (34a); a holding structure (50) holding the reactant fluid module (20) and the thermal control fluid module (30); and a gap (25) separating the first major planar surface (24a) from the second major planar surface (34a). The gap (25) comprises an interchangeable or replaceable substance or sheet (26) having a thermal resistance G across the gap (25), wherein G is not equal to R.
摘要:
A microreactor device (100) comprises a microcircuit (110) defining a reaction microchamber (112) containing a liquid and reaction medium (114), in which a chemical reaction takes place generating the gas (116), and is characterized in that the device (100) is disposed substantially vertically or inclined, defining an upper part (120) and a lower part (130) of the microchamber, and in that means (150) are provided in the upper part (120) of the said microcircuit for the in situ collection and removal of the gas formed during the reaction.
