Abstract: A system for producing biocoal and biochar includes at least one rotary compression unit (RCU) having a barrel, a compression screw housed within the barrel, a feed for receiving biomass and at least one exit for releasing biochar and gasses formed in the RCU. A first exit stream is produced that includes biochar and a portion of the remaining gasses, and a second exit stream is produced that includes biocoal. A gas crossover is provided that connects the first and second exit stream having a mechanism for transporting gasses from the first exit stream to the second exit stream thereby condensing a portion of the remaining gasses into the biocoal. In one form two RCUs are included connected to two condensers.

Abstract: A fertilizer/soil conditioner or a fuel source material is formed by processing animal waste by-products through the use of a rotary biomass dryer system. The animal waste by-product includes without limitation manure obtained from cattle or swine; feed lot bedding, poultry litter, a digestate of animal waste by-products obtained from an anaerobic digester, municipal waste, waste meat renderings, waste meat, or a mixture thereof. The processed material may comprise a higher amount of ash and a lower amount of volatile material than the animal waste by-product. The processed material may be stored as a powder or processed into pellets, logs, pucks, briquettes or another convenient shape form.

Abstract: The invention relates generally to dual mode bipropellant chemical rocket propulsion systems to be used in aerospace applications for 1) orbit raising, orbit maneuvers and maintenance, attitude control and deorbiting of spacecraft, and/or 2) propellant settling, attitude and roll control of missiles, launchers and space planes. The present invention also relates to a dual mode chemical rocket engine for use in such systems. The engine uses low-hazardous storable liquid propellants and can be operated either in monopropellant mode or in bipropellant mode. The monopropellants used are a low-hazard liquid fuel-rich monopropellant, and a low-hazard liquid oxidizer-rich monopropellant, respectively.

Abstract: The present invention relates to a reactor for the decomposition of ammonium dinitramide-based liquid monopropellants into hot, combustible gases for combustion in a combustion chamber, and a rocket engine or thruster comprising such reactor, wherein the reactor comprises a heat bed exhibiting catalytic activity.

Abstract: Preparation of sintering resistant hexaaluminates, AAl11O18, wherein A is an alka-line earth or rare earth metal, and more particularly lanthanum, by a combination of sol-gel and microemulsion techniques using a water soluble salt of A, and a method of forming spherical pellets thereof are disclosed.
