Fuel briquetting composition and the manufacturing of fuel briquettes using it |
(57) A fuel briquetting composition comprising a mixture of fuel particles, e.g., coal
or petroleum coke, an alkaline phenol-formaldehyde resin, an esterified phenol-formaldehyde
resole resin, a water-activatable green strength additive and water. Fuel briquettes
can be made using this mixture by forming it into briquettes and allowing the resinous
components of the mixture to react with the result of hardening the briquettes.
The use of an esterified phenol-formaldehyde resole resin as the curing agent for
the alkaline phenol-formaldehyde resin binder has the advantage that the reaction
product does not result in the incorporation of unreactive by-products into the polymer
matrix which would, if present, lower the water resistance of the product.
