Abstract: Ammonium sulfate nitrate double salts may be produced using a process that result in complete or nearly complete conversion to the 2:1 double salt. In some embodiments, the disclosure pertains to methods of controlling moisture content during the production process.

Abstract: A fast pyrolysis system employs a plant for use in the processing of bio-fuels. The plant includes a base frame having a first end and a second end, as well as a first lateral side and a second lateral side. The plant also includes an inlet shaped and dimensioned for the input of carbonaceous feedstock mounted to the base frame adjacent the first end, a reactor chamber mounted to the base frame and coupled to the inlet by a feed mechanism which directs carbonaceous feedstock from the inlet to the reactor chamber, a condenser system positioned and supported along the first lateral side of the base frame by a vertical supporting framework, a char separation and recovery system mounted upon the base frame and coupled to the reactor chamber by an auger for transporting char and heat carrier from the reactor chamber to the char separation and recovery system, and a heat exchanger circulating the heat carrier from the char separation and recovery system back to the reactor chamber.
