A new chemical additive for biodiesel fuel offered by Dover Chemical Corp. of Ohio is formulated to prevent engine deposits. "It acts as a detergent to prevent carbon contamination on engines," said Corky Thacker, spokesman for Dover.

Polyisobutylene succinic anhydride (PIBSA) is a versatile chemical intermediate that adds functionality, particularly dispersion, to hydrocarbon products used in a wide range of applications including biodiesel. Dover also manufactures PIB succinimide (PIBSI) derivative for commercial scale operations. "It's an alternative to the polyethers currently being used in the market," Thacker said.

With the increase in biodiesel blended into petroleum there have been complaints about increased deposits, said Brad Barth of Dover. "So biodiesel marketers who offer fuel packages to distributors can leverage their use of PIBSA and PIBSA as selling points that their products will have minimal deposit formation," he said.

Dover supplies PIBSA and PIBSI in drums, totes, tank wagons and rail cars to customers in North America, available through Dover's parent company, ICC Industries Inc.
