Abstract
The present invention relates generally to methods and systems for mixing at least two different solid materials (e.g., adsorbents) and loading the mixture into a vessel, such as an adsorption vessel or reactor.
Claims28
A method of mixing at least two solid materials in the form of free flowing particles, the method comprising:
- discharging a first material from a first discharge hopper onto an inner surface of a main funnel such that substantially all of the first discharged material directly impacts the inner surface of the main funnel within a first predetermined distance from a central axis of the main funnel;
- discharging at least one second material from at least one second discharge hopper onto the inner surface of the main funnel such that substantial all of the at the least one second discharged material directly impacts the inner surface of the main funnel within a second predetermined distance from the central axis of the main funnel;
- wherein upon impact on the inner surface of the main funnel, the at least first and second materials bounce from the inner surface of the main funnel to form a homogeneous mixture [with one another] and the volume percentage of the at least first and second materials in the mixture is controlled by the flow area of each of the discharge hoppers to obtain a predetermined composition.

- wherein upon impact on the inner surface of the main funnel, the at least first and second materials bounce from the inner surface of the main funnel and form a homogeneous mixture with one another;
- and
- wherein the discharging of the first and second materials can be continuously adjusted based on feedback from a microprocessor to form a homogenous mixture having a variation of the first and second materials in the mixture is less than 10%.
