## Abstract

The invention comprises a product. The product comprises a carbonation aid or a microporous material or a combination thereof and a carbonatable mineral containing one or more of un-carbonated Ca, Mg, Na, K, Fe, wherein the carbonation aid facilitates the conversion of one or more of CaO, MgO, Na2O, K2O or FeO to a carbonate or a CO3 containing mineral in the presence of CO2, wherein the carbonatable mineral has a volume-based mean particle size of less than or equal to 100 μm and wherein one or more of the carbonation aid or a microporous material or a combination thereof or the carbonatable mineral has carbon dioxide bound thereto at a concentration greater than its atmospheric concentration.

## Claims

### Claim 1

A product comprising:

### Claim 7 (depends on 1)

The product of claim 1, wherein the carbon dioxide adsorbent clay is a phyllosilicate clay.

### Claim 8 (depends on 1)

The product of claim 1, wherein the carbon dioxide adsorbent clay is smectite, kaolinite, bentonite, montmorillonite, saponite, sepiolite, palygorskite, or mica either in a raw state, calcined, partially calcined, acid treated, microwave treated, organically modified or synthetically modified.

### Claim 9 (depends on 1)
