Definitions
- the invention relates generally to the use of inorganic carbonates in the conversion of biomass, and more specifically to the decomposition and regeneration of such inorganic carbonates.
- Inorganic carbonates in particular sodium carbonate and potassium carbonate, have been proposed as catalysts for the conversion of biomass. It is also known that carbonates, in particular potassium carbonate, are formed as a byproduct of the conversion of certain types of biomass.
- carbonates in particular potassium carbonate
- the role of inorganic carbonates in biomass conversion has been poorly understood, which has led to on the one hand a sub-optimal use of these carbonates and, on the other hand, to an undesirable accumulation of carbonates in biomass conversion reactors due to the formation of carbonates as a byproduct.
- the present invention addresses these problems by providing a process for the catalytic conversion of solid biomass material, said process comprising the steps of:
- Another aspect of the invention comprises a method for recovering heat from char and coke that are formed during the biomass conversion.
- the step of regenerating the hydroxide to the corresponding carbonate is combined with the step of recovering heat from char and coke.
- the present invention is based on the discovery that inorganic carbonates decompose to the corresponding metal oxide and carbon dioxide under conditions that are suitable for their catalytic conversion of biomass material to a bio-oil.
- the temperature in step (i) is generally in the range of from 200°C to 500°C, more preferably in the range of from 350°C to 450°C. These temperatures are normally not considered high enough to cause the decomposition of inorganic carbonates. However, due to interactions that exist between the carbonate and the biomass material, at least partial decomposition of the organic carbonates occurs at these temperatures.
- bio-oil that is formed in the conversion of biomass is highly acidic, due to the presence of organic acids such as carboxylic acids.
- bio-oils produced in these reactions have a pH of less than 3. This is low enough to convert an inorganic carbonate to the corresponding hydrogen carbonate, or bicarbonate.
- the bicarbonates are thermally considerably less stable than the carbonates from which they derive.
- the reaction is self catalyzed.
- the formation of a small amount of a bio-oil lowers the pH, thereby accelerating the decomposition of the carbonate.
- the metal hydroxide resulting from the decomposition of the carbonate access a sink for the acidic bio-oil compounds that are formed. The presence of the metal hydroxide thereby facilitates the formation of the acidic bio-oil.
- regeneration of the hydroxide to the carbonate may take place in situ , as sufficient CO 2 may be formed in the biomass conversion to react at least some of the hydroxide back to the corresponding carbonate. This may be a reason why the need for regeneration is not generally recognized by those active in this field.
- biomass material from most sources contains considerable amounts of inorganic materials, which form a solid byproduct generally referred to as "ash".
- ash a solid byproduct
- at least part of the ash will be in the form of inorganic carbonates.
- the process of the present invention addresses the former issue by providing a regeneration step in which hydroxide is converted to the corresponding carbonate.
- the process of the invention addresses the latter issue by recovering carbonates present in the ash by-product and recycling them back into the process to the extent required.
- the process of the invention is suitable for conversion of any type of solid biomass material to form a bio-oil.
- the process is particularly suitable for the conversion of biomass comprising cellulose.
- the biomass feedstock used in the process may further comprise lignin.
- An important aspect of the process of invention is the formation of bio-oil.
- part of the biomass is converted to non-condensable gases.
- the solid residue may contain any unconverted solid biomass material.
- the solid residue further comprises solid reaction products of the biomass conversion reaction, in general coke and char.
- the inorganic materials present in the biomass feedstock to some extent end up in the gas phase in the form of fly ash; for the most part, however, the ash is present in the solid residue, generally embedded in the char.
- any inorganic carbonate that was added to the reaction mixture will also find its way to the solid residue of the biomass conversion reaction.
- at least some of the inorganic carbonate may be present in the solid residue in the form of the hydroxide.
- a suitable example of an oxygen containing gas is air.
- Heat generated by burning the char and/or coke can be used to supply heat to the biomass conversion step.
- Significant amounts of CO 2 are formed during the burning of the char and coke.
- Any metal hydroxide or metal oxide present in the solid residue is converted to the corresponding carbonate during this regeneration step.
- a suitable regeneration temperature is in the range of from 550°C to 800°C, typically around 650°C.
- Regenerated carbonate is recycled back into step (i).
- the carbonate particles may be used to carry heat from the regeneration reaction to the biomass conversion step.
- any inorganic carbonate is suitable for use as a catalyst in step (i) of the process.
- Particularly suitable are the carbonates of the monovalent and divalent metals.
- the monovalent alkali metals are particularly preferred, especially sodium and potassium.
- the ash formed in the solid residue of the biomass conversion reaction may comprise the oxide, the hydroxide or the carbonate of alkali metals and earth alkaline metals.
- the ash can be converted to the carbonate ash in step (ii), and the carbonate ash can be recycled to step (i).
