  • Patent number: 9611439
    Abstract: The present invention relates to a method of fractionating bio-oil vapors which involves providing bio-oil vapors comprising bio-oil constituents. The bio-oil vapors are cooled in a first stage which comprises a condenser having passages for the bio-oil separated by a heat conducting wall from passages for a coolant. The coolant in the condenser of the first stage is maintained at a substantially constant temperature, set at a temperature in the range of 75 to 100° C., to condense a first liquid fraction of liquefied bio-oil constituents in the condenser of the first stage. The first liquid fraction of liquified bio-oil constituents from the condenser in the first stage is collected. Also disclosed are steps for subsequently recovering further liquid fractions of liquefied bio-oil constituents. Particular compositions of bio-oil condensation products are also described.

  • Patent number: 6146842
    Abstract: A high throughput enzyme screen has been developed which relies on metal chelate interaction for capture of the product of the enzymatic reaction. In the present assay system, a detectable moiety is attached to a substrate having a chelating capturable moiety, which can be captured by an immobilized metal. Detection is effected due to the presence of a detectable label on the reaction product immobilized on the solid phase. Only signal associated with tagged protein bound to the solid phase is detected. The present assay can reliably measure enzyme activity, and has high reproducibility, which benefits high throughput screening.
