Separation device and chemical reaction apparatus made from polycrystalline diamond, apparatuses including same such as separation apparatuses, and methods of use

摘要

The present invention relates to a porous polycrystalline diamond structure that may be employed as a separation device in a separation apparatus for separating at least one reaction product of a chemical reaction, as a stationary phase support and/or stationary phase in chromatography or separation apparatuses, or as a chemical reaction apparatus for conducting a chemical reaction therein. A separation device includes a body of sintered diamond particles. The body includes a proximal inlet end, a distal outlet end, and an intermediate region therebetween. The body further includes a plurality of at least partially interconnected pores that extend between the proximal inlet end and the distal outlet end. The at least partially interconnected pores are capable of communicating fluid from the proximal inlet end to the distal outlet end. Separation apparatuses that utilize the separation device, such as gas or liquid chromatography apparatuses, and chemical reaction apparatuses are also disclosed.

1. A separation device, comprising:
a sintered body comprised of a plurality of diamond-to-diamond bonded grains extending from a proximal inlet end to a distal outlet end and through an intermediate region between the proximal inlet end and distal the outlet end, the body further including a plurality of at least partially interconnected pores disposed among the plurality of diamond-to-diamond bonded grains, wherein the at least partially interconnected pores provide at least one fluid passage that extends through the sintered body from the proximal inlet end to the distal outlet end, wherein the pores associated with the at least one fluid passage exhibit a larger pore size at a location adjacent the proximal inlet end than they do at a location adjacent the distal outlet end.
