Definitions
- Examples 4 and 5 pertain to conversion of a partially or non-bleached kraft paper sludge.
- the cellulose content of this sludge has been measured to be 80% by weight on average. That is, 100 lbs of bone dry sludge contains 80 lbs of cellulose which is available for conversion to levulinic acid.
- Example 6 pertains to conversion of raw wood flour. The cellulose content of this has been measured to be, on average, 42% by weight. That is, 100 lbs of bone dry sludge contains 42 lbs of cellulose which is available for conversion to levulinic acid.
- EXAMPLE 4 1.02 liters per minute of a 1.0% by weight slurry of paper sludge originating from a non-bleached Kraft pulping process containing 1.15% by weight of the aqueous portion sulfuric acid is fed to the reactor system.
- the first stage tubular reaction is fifteen feet in length and 0.41 inches in inside diameter.
- High pressure steam is injected into the process stream at an average rate of 0.476 liters per minute (condensed volume) as it passes into the tubular reactor.
- the residence time of the reaction mixture in the first stage tubular reactor is 14 seconds.
- the mixture passes through the pressure let ⁇ down valve and flashes directly into the second stage reactor vessel via the dip tube.
- the second stage reactor is a 10 inch I.D.
- the liquid product outflow containing levulinic acid was measured at 1.34 liters per minute and the vent outflow was measured at 0.02 liters per minute after condensation.
- the levulinic acid and glucose concentration in the liquid outflow was measured at steady state after three and a half hours of operation.
- the yield of levulinic acid was calculated to be 71% of theoretical. No levulinic acid was measured in the vent stream.
- EXAMPLE 6 0.70 liters per minute of a 10% by weight slurry of hardwood flour containing 5.0% by weight of the aqueous portion sulfuric acid is fed to the reactor system.
- the first stage tubular reactor is fifteen feet in length and 0.41 inches in inside diameter. High pressure steam is injected into the process stream at an average rate of 0.65 liters per minute (condensed volume) as it passes into the tubular reactor.
- the residence time of the reaction mixture in the first stage tubular reactor is 15.7 seconds.
- the mixture passes through the pressure let-down valve and flashes directly into the second stage reactor vessel via the dip tube.
- the second stage reactor is a 10 inch I.D. (Schedule 20 pipe section) vessel of overall length 27 inches.
- the liquid product outflow containing levulinic acid was measured at 1.15 liters per minute and the vent outflow was measured at 0.23 liters per minute after condensation.
- the levulinic acid concentration in the liquid outflow was measured by analysis to be 1.05% at steady state.
- the product outflow from the reactor system was therefore calculated to be 0.0121 kg per minute representing a yield of levulinic acid of 62% of theoretical.
- a small quantity (0.000069 Kg per min) of levulinic acid was measured in the vent stream this was accounted for as additional yield.
