2756 results about "Corn stover" patented technology

Corn stover consists of the leaves, stalks, and cobs of maize (corn) (Zea mays ssp. mays L.) plants left in a field after harvest. Such stover makes up about half of the yield of a corn crop and is similar to straw from other cereal grasses; in Britain it is sometimes called corn straw. Corn stover is a very common agricultural product in areas of large amounts of corn production. As well as the non-grain part of harvested corn, the stover can also contain other weeds and grasses. Field corn and sweet corn, two different types of maize, have relatively similar corn stover.

Integrated process for separation of lignocellulosic components to fermentable sugars for production of ethanol and chemicals

A continuous and modular process converts lignocellulosic materials for the production of ethanol principally and / or chemicals such as methanol, butanediol, propanediol, hydrocarbon fuel, etc. Renewable lignocellulosic biomass such as but not all inclusive hardwoods (gum, beech, oak, sweet gum, poplar, eucalyptus, etc.), soft woods (pines, firs, spruce, etc.), corn stovers, straws, grasses, recycled papers, waste products from pulp and paper mills, etc can be used as feedstock. The process is designed to be modular and the feed entry point can be selected to adapt to different biomass feedstock. Lignocellulosic biomass such as hardwood and softwood are subjected to chemical / pressure treatment stages using potent and selective chemicals such as sodium chlorite / acetic acid (anhydrous) and chlorine / chlorine dioxide to separate the main components—lignin, cellulose (glucose) and hemicelluloses (xylose, arabinose, galactose)—into three process streams. The separated carbohydrates are further subjected to washing, cleaning, neutralization, and / or mild hydrolysis and subsequently fermented to produce ethanol. Residual lignin and extractives remained with the cellulose are removed by chemical treatment steps to enhance the fermentations of cellulose. Pre-hydrolysate after neutralization to neutralize and remove toxic components such as acetic acid, furfural, phenolics, etc. containing (xylose, arabinose, galactose) and hexoses (glucose) can be either separately or together with the purified cellulosic fraction fermented to produce ethanol. Approximately 100 gallons of ethanol, suitable to be used as a fuel, can be produced from one dried ton of wood. Significant amount of lignin are separated as a by-product and can be converted to hydrocarbon fuel, surfactant, drilling aid, or can be incinerated for generation of power and steam.
