      Gasification. Like coal gasification, biomass gasification operates at high temperatures (> ° C) with steam or air or oxygen, and can be tuned to make “synthetic natural gas” (SNG), i.e. methane, or synthesis gas (CO, H 2, CO 2). Several processes occur in a gasification reactor, as shown in Figure 2 for a typical down-flow gasifier.

Black liquor gasification occurs in several stages: drying of the black liquor droplets, devolatilization or pyrolysis, gasification of the resulting char and, depending on the temperature, coalescence and melting of the inorganic salts.

The knowledge of each of these individual stages is important for a better understanding of the global by: 1. simultaneously using the GC-FID.8 With the success of these methods using the FID, capillary gas chromatography-mass spectroscopy (GC-MS) seemed an ideal approach. Although the MS detector is more expensive, the GC-MS combines all the positive aspects of this methodology and promises very accurate results using a variety of source matrices and.

-MS analysis of these extracts were performed using a Perkin Elmer GC Clarus and Gas chromatograph interfaced to a Mass spectrometer (GC-MS) equipped with a Journal of Applied Pharmaceutical Science 01 (09); tightly.

Properly executed, GC/FID should be an ideal tool for this sort of quantitative analysis, because the ethanol matrix of whiskey along with all the trace components are of a class that is easily detected by FID to high accuracy, due to the dominating presence of hydrocarbons in the sample.

Sample preparation for mass spectrometry is used for the optimization of a sample for analysis in a mass spectrometer (MS). Each ionization method has certain factors that must be considered for that method to be successful, such as volume, concentration, sample phase, and composition of the analyte solution.

Quite possibly the most important consideration in sample preparation.

Black liquor can be gasified and then combusted in a turbine to generate electricity. With a heat recovery steam generator (HRSG), the plant can be run in a combined cycle, similar to an integrated gasification combined cycle (IGCC).This specific configuration using black liquor is sometimes called a black liquor gasification combined cycle (BLGCC).
