  • Method to upgrade bio-oils to fuel and bio-crude
    Patent number: 8603199
    Abstract: 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.

  • Container for 4-allylanisole and analog scolytid pesticides
    Patent number: 6306913
    Abstract: A projectile can be used to administer pesticides such as one or more from the group consisting of 4-allylanisole, anisole, allylbenzene, 4-isopropylanisole, p-anisaldehyde, ethylbenzene, cumene, 4-methoxyacetophenone, 4-methylstyrene, 2-propylphenol, phenetole, and toluene, for scolytid infestation. Conifers, which are a target for scolytids, are protected by the application of the pesticides by use of a projectile containing the compound which explodes upon contact with the conifer thereby emitting the compound.

  • 4-allylanisole analog scolytid repellents
    Patent number: 5518757
    Abstract: 4-allylanisole, and three analogs, anisole, allylbenzene, and 4-isopropylanisole are demonstrated to be effective repellents for scolytid infestation. Conifers, a particular target for the scolytids, are protected by application of the compounds, either directly or suspended in a carrier.
