Synthetic diesel fuel from coal - Energy And Climate

A decade ago, subsidies for biofuel growth and development in many countries (especially the U.S.) were high. However, better understanding of global warming, increased awareness of the fragility of the food supply, and a general trend toward “greener” alternatives have all led to a decline in the popularity of biofuels. In 2011, The U.S. Senate voted 73 to 27 to end tax credits and trade protections for corn-based ethanol production. As the second largest producer of ethanol, this is a substantial move that reflects the changing pressures on our energy needs and shifted focus to environmentally friendly energy sources.

Once separated from the glycerin, the biodiesel is sometimes purified by washing gently with warm water to remove residual catalyst or soaps, dried, and sent to storage. In some processes this step is unnecessary. This is normally the end of the production process resulting in a clear amber-yellow liquid with a viscosity similar to petrodiesel. In some systems the biodiesel is distilled in an additional step to remove small amounts of color bodies to produce a colorless biodiesel.
