TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Method: The gasification temperature is 300-800 degrees C. In method (M1), the methyl cyclopentadienyl manganese tricarbonyl combined at 0.5-10 wt.% with the biomass comprises wood chips, where the biomass and organometallic compound are fed into a gasifier combustion unit containing a heating medium, fluidized with a flowing gas comprising nitrogen, and heated to a temperature of 300-800 degrees , where gasification product is produced. Preferred Biomass: The biomass is selected from wild and/or anthropomorphically cultivated, and/or genetically engineered, and/or bioengineered trees, bushes, grasses, algae, plankton, aquatic plants, animals, yard trimmings and waste, wood chips, saw dust, mariculture products, animal parts and carcasses, animal waste, farm waste, agricultural waste, fodder, silage, organic waste and/or by-products, and their mixtures, and emulsions, suspensions, and/or dispersions in water, alcohol, or other carrier fluids.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The organometallic compound is selected from cyclomatic manganese carbonyl compounds, manganese carbonyl materials, ferrocene, iron carbonyl materials, cerium-containing compounds, and/or platinum group metal compounds. The biomass is selected from coal, coal dust and their mixtures, and emulsions, suspensions, and/or dispersions in a carrier fluid.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The organometallic compound is selected from methyl cyclopentadienyl manganese tricarbonyl, and cyclopentadienyl manganese tricarbonyl (preferably methyl cyclopentadienyl manganese tricarbonyl and is present in a resulting biomass plus organometallic compound mixture at a weight ratio of greater than 11%). In method (M3), the components are selected from levoglucosans and hydroxyacetaldehydes; or sugars, carbohydrates and carboxy phenols.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: In method (M2), the aromatic rings of materials in the biomass are selected from lignin heteropolymer backbones derived from guaiacyl and syringyl monomers.
