Abstract
Systems and methods for fabricating bodies (e.g., porous bodies) are described. Various aspects provide for reactors and the fabrication of reactors. Some reactors include surfaces that provide for heterogeneous reactions involving a fluid (and/or components thereof). A fluid may be a gas and/or a liquid. A contaminant in the fluid (e.g., a dissolved or suspended substance) may react in a reaction. A contaminant may be filtered from a fluid. Some reactors provide for independent control of heat transfer (between the fluid, the reactor, and the environment) with respect to mass transfer (e.g., fluid flow through the reactor).
Claims20
A substrate for use in a reactor having an inlet and an outlet, a line from the inlet to the outlet defining a flow direction, the substrate comprising:
- a first end configured to be in fluid communication with the inlet;
- a second end configured to be in fluid communication with the outlet;
- and
- a first channel having a porous wall and open to at least one of the inlet and the outlet, the first channel having a shape that causes a fluid flowing through the first channel to take a second direction that deviates from the flow direction by at least 5 degrees.
A method for fabricating a body, the method comprising:
- delivering a first layer comprising particles of a substrate material and a fugitive phase;
- bonding a portion of the first layer to attach the particles within the bonded portion to each other and to a previously delivered second layer beneath the bonded portion of the first layer;
- removing an unbonded portion of the first layer;
- and
- firing the bonded portion to remove the fugitive phase.
A method for fabricating a body, the method comprising:
- delivering a first layer comprising particles of a cementitious material;
- delivering an aqueous fluid to at least a portion of the first layer to create a bonded portion of the first layer, the bonded portion comprising cementitiously bonded particles attached to each other and to a previously delivered second layer beneath the bonded portion of the first layer;
- and
- removing an unbonded portion of the first layer to yield a cementitiously bonded body.
