Microreactor process for making biodiesel

USPTO Application #: 20090165366
Title: Microreactor process for making biodiesel
Abstract: Embodiments of a method for using a microreactor to produce biodiesel. For example, the method may comprise flowing a first fluid comprising an alcohol and a second fluid comprising an oil to the microreactor. Alcohols typically, but not necessarily, are lower aliphatic alcohols, including methanol, ethanol, amyl alcohol or combinations thereof. Biodiesel production can be under supercritical conditions, where such conditions typically are determined relative to the alcohol component. Suitable sources of oil products include soy, inedible tallow and grease, corn, edible tallow and lard, cotton, rapeseed, sunflower, canola, peanut, safflower, and combinations thereof. Catalysts can be used to facilitate biodiesel production, such as metal oxides, metal hydroxides, metal carbonates, alcoholic metal carbonates, alkoxides, mineral acids and enzymes. Oil conversion to biodiesel typically increases with increasing mean microreactor residence time. Certain embodiments of the present invention can include blending biodiesel produced by the method with petroleum-based products. (end of abstract)

  monitor keywords CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Application No. 60/810,569, filed on Jun. 1, 2006. The entire disclosure of the provisional application is considered to be part of the disclosure of the following application and is hereby incorporated by reference.

FIELD

The present disclosure concerns embodiments of a process for making biodiesel, particularly a process that utilizes at least one microreactor device.

BACKGROUND A. Biodiesel Generally

Biodiesel is registered with the U.S. Environmental Protection Agency as a pure fuel or as a fuel additive, is a legal fuel for commerce, and meets clean diesel standards established by the California Air Resources. Its physical and chemical properties as they relate to operation of diesel engines are similar to petroleum-based diesel fuel as per the ASTM fuel tests shown in Table 1.
