Title:
COAL-DERIVED CARBON-BASED INSULATION FOAM AND METHODS OF MAKING THE SAME
Document Type and Number:
WIPO Patent Application WO/2024/072946
Kind Code:
A3
Abstract:
Embodiments of the present disclosure related carbon-based foams (CBF). The CBF includes a cured composition. The cured composition includes about 5% to about 20% pyrolysis char (PC) by weight and about 80% to about 95% lignin solution by weight. The lignin solution includes a lignin and a solvent. The solvent includes water, a polyol and a polyisocyanate. A method of making a composition includes grinding and sieving a pyrolysis char (PC) to form a PC powder; mixing a lignin with a solvent to form a lignin solution; mixing the PC powder with the lignin solution to form a lignin-PC solution; mixing a surfactant and a catalyst with the lignin-PC solution to form a raw materials mixture; mixing a foaming agent with the raw materials mixture to form a lignin-PC foam; and curing the lignin-PC foam to form a CBF.
