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 distillers dried grains with solubles (DDGS). The ethanol is boiled off as vapor and then condensed back into a liquid in a process called distillation.

STEP 5
Transportation

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