Definitions
- Gasification of biomass by thermal methods involving pyrolysis and/or partial oxidation is known as a method to produce a synthesis gas, composed of carbon oxides and hydrogen, or a fuel gas.
- Many of the known methods use a dry biomass feedstock with less than 10 wt % moisture.
- much of the biomass resource contains higher levels of moisture, more typically 50 wt% and some even consist of wet biomass, or biomass in water slurries at 85 wt% moisture or higher.
- One approach to efficiently process such wet biomass is gasification employing an active catalyst in a pressurized water environment (e.g., hydrothermal gasification).
- the present invention includes apparatuses and methods for treating wet biomass by catalytic hydro thermal gasification that address the problem of poisoning and fouling of the catalyst, especially for long-term and/or continuous use.
- the inorganic wastes that precipitate in the catalyst and cause plugging and poisoning can be precipitated by heating the wet biomass feedstock prior to exposure to the catalyst.
- treatment of the wet biomass feedstock comprises heating the wet biomass with a heating unit to a temperature sufficient for organic constituents in the feedstock to decompose, for precipitates of inorganic wastes to form, for preheating the wet feedstock in preparation for subsequent separation of sulfur contaminants, or combinations thereof.
- Treatment further comprises separating the precipitates out of the wet feedstock, removing sulfur contaminants, or both using a solids separation unit and a sulfur separation unit, respectively. Having removed much of the inorganic wastes and the sulfur that can cause poisoning and fouling, the wet biomass feedstock can be exposed to the heterogeneous catalyst for gasification.
- biomass refers to biological material that can be used for fuel or for industrial production.
- Exemplary biomass can include, but is not limited to, biosludge from wastewater treatment facilities, sewage sludge from municipal treatment systems, wet byproducts from bioreflnery operations, wet byproducts/residues from food processing, animal waste and waste from centralized animal raising facilities, organic chemical manufacturing wastewater streams, and industrial wastewater containing organics.
- Biomass commonly comprises organic matter that can be treated in a continuous reactor, according to embodiments of the present invention, to yield a gas containing hydrogen or useful for hydrogen production (e.g., methane).
- Common inorganic contaminants, which can poison and/or foul the catalyst can include, but are not limited to minerals comprising Ca, Mg, P, and/or Fe.
- the heterogeneous catalysts comprise Ru, Ni, and/or Ni with added Na.
- the Na can be in the form of a sodium carbonate co-catalyst.
- the catalyst comprises Ru on a carbon support.
- the catalyst can be configured to gasify Ih ⁇ organic constituents into a hydrogen- containing feedstock' for subsequent catalytic reformation.
- Separation of solids from the heated wet biomass feedstock can be achieved using a solids separation unit, which can include, but is not limited to, a gravity separation unit, a hydrocyelonie separation unit, and/or a filtration unit.
- Removal of sulfur can be achieved using a sulfur separation unit comprising, for example, an adsorbent bed with a metal or metal oxide.
- the catalytic hydro thermal gasification occurs at conditions in which water is below its critical point (i.e., sub-critical), in a particular embodiment, the wet biomass feedstock is heated to at least 300 0 C. In another embodiment, a catalytic reactor containing the heterogeneous catalyst is heated to a temperature between 250 0 C and 374 0 C. The pressure in the catalytic reactor can be up to 23 MPa. In a preferred embodiment the catalytic reactor is operated at temperatures between 340 0 C and 360 0 C and pressures between 18 MPa and 21 MPa.
- FIG. 1 is a diagram depicting system for hydrothcrmal gasification of biomass according to one embodiment of the present invention.
- the wet biomass feedstock typically comprises at least two types of solids that can clog, plug, and/or poison the catalyst including organic matter and mineral materials.
- proper preheating of the biomass feedstock can transform the solid organic matter to liquid and/or gas, both of which can pass into the catalytic reactor without causing plugging and/or poisoning.
- char can be a major product at sub-critical conditions.
- the present invention also calls for sub-critical operating conditions and provides approaches for the minerals to be precipitated and separated from the stream while allowing the liquefied biomass organics to pass on to the catalytic reactor. With the solids separated, a sulfur scrubber bed could also be used without plugging, as well as the catalytic bed for gasification.
- a more stable nickel catalyst was used and was effective (97.7% COD reduction @ 2.3 LHSV) but lost activity (71.2% COD reduction @ 2.0 LHSV) after several hours.
- Analysis of the catalyst showed deposits of biomass-derived minerals on the catalyst such as hydroxylapatite (Ca 5 (PO ⁇ )OH) and nickel subsulfid ⁇ (Ni 3 S 2 ).
- apatite and nickel subsuifide but also iron phosphate, ammonium iron sulfate, potassium alurainosiiicate, calcium carbonate, calcium magnesium sulfate, and anorrhoelasc, an alkali silicoaiuminate. All of these precipitates were attributed to components in the biomass feedstock. Furthermore, in tubular-reactor-only configurations, biomass slurry pumping difficulties became evident. Processing of slurries of ground potato or apple peels were short-lived because of pump failures and plugging of solids at the front end of the catalytic bed. The plugging appeared to be primarily organic solids produced from partially pyrolyzed biomass. These short-lived tests verified the high activity (95.4% COD reduction @ 2.67 LHSV) of the ruthenium stabilized nickel catalyst for biomass gasification.
- a continuous-flow reactor system comprises a wet biomass feedstock heater, a sulfur removal unit, a solids separation unit, and a catalytic reactor.
- FIG. 1 One particular system similar to the one illustrated in Fig. 1 was based on a throughput of 0.5-10 Ib of slurry or solution per hour and was typically operated over a range of 1 to 3 liter/hour. These operating parameters are not to be construed as limitations to the present invention, but are rather descriptive by way of example.
- Slimy feeding to the pressurized system was accomplished using a syringe pump having a large-bore valve package that controls the feeding from one cylinder or the other.
- the valve package comprised four 3/8-inch air-actuated (6000 psi rated) ball valves with 3/8- inch stainless steel (SS) tubing connections. Oversize caps were installed on the barrels that accommodate 3/8-inch NPT fittings.
- the large bore head, valve, and tubing allowed suctioning and pumping of the viscous slurries while still allowing the pump to operate at 3500 psi max. All valves and valve trim (except the pressure-control valve) were made of SS. The feeding rates were measured directly by the screw drive of the positive displacement syringe pump.
- the preheater was a 1 -liter 316 SS vessel that functioned as a continuous- flow, stirred-tank reactor in which the feedstock was brought to the reaction temperature.
- the organics in the biomass were pyrolyzed and liquefied while inorganic components, such as calcium phosphates, formed and precipitated as solids.
- the catalytic reactor was constructed of 304 SS and had an inner diameter of one inch with a length of 72 inches.
- the reactor had boltcd-closurc cndeaps with metal o-rings on each end.
- Catalyst pellets were supported in the reactor on a circle of fine screen.
- the reactor furnace was a 6-kWe resistance heater split into three separately controllable zones. The pressure was controlled with a dome-loaded diaphragm backpressure regulator.
- a solid separations unit was placed in the process line between the preheater and the reactor to capture and remove the solids before they reached the catalyst bed, where, in previous tests, they have collected and caused flow plugging.
- a sulfur scrubber trap incorporated a chemical trap for reduced sulfur forms.
- the sulfur components reacted with the trap material to form insoluble sulfide, which prevented their passing into the catalyst bed where they could react with the metal of the catalyst and destroy its catalytic capability.
- the mineral recovery system recovered a solid with 91 % ash content and which accounted for less than 1% of the carbon in the feedstock. Phosphate in the feedstock at about 2700 ppm was found to be absent, ⁇ lppm, following the processing.
- Phosphate in the feedstock at about 940 ppm was found to be absent, ⁇ lppm, following the processing. Sulfate was also present in the feed at 35 ppm but was found in the range of 2 to 10 ppm in the effluent.
