Quality Products, Tested Processes

Ethanol is a high octane, high performance, renewable fuel used as an oxygenate in gasoline. Marquis’ ethanol is produced through the age-old process of fermentation, combined with cutting-edge and revolutionary enzymatic technological developments, to convert the starch in corn to fermentable sugar.

STEP 1
Storage & Milling

Corn is received by truck and stored in bins before being continuously ground into flour and fed to production.

STEP 2
Saccharification

During saccharification, complex carbohydrates (starch) are broken down into simple sugars or glucose.

STEP 3
Fermentation

Fermentation is the process by which a yeast organism converts simple sugars (glucose) into ethanol.

STEP 4
Distillation & Drying

Following fermentation, the remaining unfermented solids are removed and dried to produce dried distillers grain (DDG). The ethanol is boiled off as vapor and then condensed back into a liquid in a process called distillation.

STEP 5
Transportation

The ethanol, DDG or corn oil is then loaded into a truck, railcar, or barge for delivery all around the world.
