Corn Stover Agglomerates for Oil Absorption

详细技术说明

Lightweight, Biodegradable Alternative to Clay-Based SorbentsA lightweight, biodegradable oil absorbent material created from corn stover shows desirable oil sorbency characteristics, making it an effective alternative to clay-based sorbents. Dust-free corn stover agglomerates are produced by a gentle agglomeration and rolling action using a novel, two part bonding system that forms a web onto which additional particles adhere and roll upon. The web is formed as a result of crosslinking of liquid and solid portions of binding system. The cellular structure of the corn stover is conserved: particles remain intact in an undensified, “non-collapsed” state, allowing oil and other hydrocarbon fluids to wick into its porous structure. The ground corn stover is gently agglomerated into 4 to 8 mm beads with a very high open porosity, creating pore surfaces and pore volume for oil and other liquids to be captured.Better Sorbency, Significantly Less Ash, and More Recoverable EnergyConventional technology, such as compression pelleting, uses high compression dies where material is forced under friction through a die cavity. This new process uses gentle growth agglomeration, where properly prepared feed is self-agglomerated in a balling drum, disc or tire with significant emphasis on minimal densification, assuring the delicate corn stover fibers are attached to one another with pendular bridging. Overall, the process creates agglomerate sooner, at lower moisture and with superior green strength compared to single stage binders. Compared to conventional clay based absorbents, agglomerated corn stover fiber has over 5 times more sorbency, significantly less ash, and provides more recoverable energy.BENEFITS AND FEATURES:Lightweight, biodegradable oil absorbent material from corn stoverAlternative to clay-based sorbentsAgglomerated corn stover fiber has over 5 times more sorbency, significantly less ash, and provides more recoverable energy than conventional clay based absorbentsProcess creates agglomerate sooner, at lower moisture and with superior green strength compared to single stage bindersGentle agglomeration and rolling action using two part bonding systemConserves cellular structure: particles remain intact in an undensified, “non-collapsed” state, allowing oil and other hydrocarbon fluids to wick into its porous structureVery high open porositySimple process uses commonly available agricultural equipmentAPPLICATIONS:Oil AbsorbentAlternative to clay-based sorbentsAnimal and pet beddingRenewable materialsEngineered carrier for biological fertilizersPhase of Development - Pilot scale demonstration
