Dilute-sulfuric acid pretreatment of cattails for cellulose conversion.

The use of aquatic plant cattails to produce biofuel will add value to land and reduce emissions of greenhouse gases by replacing petroleum products. Dilute-sulfuric acid pretreatment of cattails was studied using a Dionex accelerated solvent extractor (ASE) varying acid concentration (0.1-1%), treatment temperature (140-180 °C), and residence time (5-10 min).

Hot-water pretreatment of cattails for extraction of cellulose.

To date in the US, production of renewable fuels, particularly ethanol, is primarily from food crops that are high in sugar and starch. The use of arable land for fuel rather than food production and the use of a food source for fuel rather than food have created issues in pricing and availability of traditional foods and feed. The use of cattails to produce biofuel will add value to land and also reduce emissions of greenhouse gases by replacing petroleum products.
