Conference Alert: Three Biofuel Conferences You May Be Interested in

 “I have left orders to be awakened at any time in case of national emergency, even if I'm in a cabinet meeting.” -- Ronald Reagan (American 40th US President (1981- 89), 1911-2004)

Three biofuels conferences, all produced by BBI International (http://www.bbiinternational.com/) are coming up soon …

1. National Advanced Biofuels Conference & Expo, September 10-12, 2013, Omaha, NE (http://www.advancedbiofuelsconference.com/ema/DisplayPage.aspx?pageId=Home)
2. Algae Biomass Summit, September 30-October 3, 2013, Orlando, Florida (http://algaebiomasssummit.org/ema/DisplayPage.aspx?pageId=About)

It may surprise newcomers to the field that the production of biodiesel requires desulfurization technology.

For example, here is an excerpt from an item produced by Preprocess Inc (www.preprocessinc.com) …

Sulfur Removal Strategies for Biodiesel
High FFA fats, oils and grease are feedstock for ASTM 6751 biodiesel. These feedstocks contain higher levels of sulfur than traditional feedstocks. Common oil crops contain sulfur species that are water soluble and remain with the meal during oil processing. High FFA feedstocks from cooking and rendering operations contain oil soluble sulfur species that require additional processing steps to produce ASTM 6751 biodiesel that meets the 15 ppm sulfur specification. It all begins with good feedstock characterization.
Biodiesel Feedstock Species and Sources
Biodiesel feedstock can contain sulfur in many different species. The most prevalent are mercaptans. They can be high molecular weight complex mercaptans with aromatic ring backbones, or simple lower molecular weight species with straight chain backbones. Other more complex sulfur containing products can be found where there is significant animal protein degradation. Characterize each feedstock for sulfur and use a high/low sulfur feedstock blending strategy targeting the average sulfur feedstock levels so the process will output the 15 ppm sulfur limit.
