This invention relates to a method and device to produce esterified, olefinated/esterified, or thermochemolytic reacted bio-oils as fuels. The olefinated/esterified product may be utilized as a biocrude for input to a refinery, either alone or in combination with petroleum crude oils. The bio-oil esterification reaction is catalyzed by addition of alcohol and acid catalyst. The olefination/esterification reaction is catalyzed by addition of resin acid or other heterogeneous catalyst to catalyze olefins added to previously etherified bio-oil; the olefins and alcohol may also be simultaneously combined and catalyzed by addition of resin acid or other heterogeneous catalyst to produce the olefinated/esterified product.

Method to upgrade bio-oils to fuel and bio-crude

Provided is a solid rocket motor (SRM) insulation, wherein carbon nano fibers (CNF) are blended into a polyurethane matrix so as to disperse the CNF in the polymer. The so blended material is then extruded, injection molded or sprayed on or into the desired shape. Such SRM insulation has reduced ablation over prior art insulations, resulting in reduction in weight of the insulation needed in such rockets, permitting increase of payload therein.

A composition for removing resists and etching residue from substrates containing at least one nucleophilic amine compound having oxidation and reduction potentials, at least one organic solvent, water and, optionally, a chelating agent is described. The chelating agent is preferred to be included since it provides added stability and activity to the cleaning composition so that the composition has long term effectiveness. If a chelating agent is not present, the composition, while providing for adequate stripping and cleaning upon initial use of the composition following mixing, has only short term stability. In this latter instance, the nucleophilic amine compound and organic solvent components of the composition preferably are maintained separate from each other until it is desired to use the composition. Thereafter, the components are combined.

A method and process for treating wood. The steps include preparing isocyanate-based reactive prepolymer resins for impregnation, impregnating wood with these impregnation resins, curing the impregnated wood at elevated temperatures, preparing isocyanate resin-based coating materials and applying these coating materials on the cured impregnated wood and curing the coatings at room or elevated temperatures. The resulting treated wood has substantially improved de-contaminability of the chemical warfare agent VX both initially and after long exposure to degradation effects from sunlight.

A process for preparing 1,7-octadiene by dimerizing butadiene in the presence of a catalytic amount of palladium acetate and a tertiary phosphine, a solvent in an amount sufficient to dissolve the catalyst, a strong base and formic acid, wherein: (a) the molar ratio of the strong base to the formic acid is 1:1-2, (b) the mole ratio of tertiary phosphine to palladium is at least 1, (c) the amount of strong base present is such that the pH of the reaction medium is from 7.5 to 10.5 and (d) the solvent is at least one member selected from the group consisting of aromatic hydrocarbons, lower alkyl substituted aromatic hydrocarbon, halogenated aromatic hydrocarbons, halogenated lower aliphatic hydrocarbons, nitriles, amides, dilower alkyl ethers, lower alkyl phenyl ethers, lower alkyl esters of lower alkanoic acids, ketones and lower alkanols.

1,7-Octadiene synthesis

A method is disclosed of delineating a desired integrated circuit pattern upon a circuit substrate. According to the method, the copolymer poly(methyl alpha-chloroacrylate-co-methacrylonitrile) is formed by emulsion polymerization techniques. The copolymer is then dissolved in a spinning solvent that will dissolve the copolymer and form a viscous solution. The solution is applied to the surface of the substrate and the substrate spinned to form a smooth, uniform resist film of about 0.3 to 1.0 micron in thickness. The resist film is heated and the region of the resist film to be patterned then exposed to ionizing radiation until exposures greater than 1.5.times.10.sup.-5 C/cm.sup.2 are obtained. The exposed regions of the resist are then developed to the substrate.
