Effect of potassium phosphate trihydrate on the pyrolysis characteristics of camphorwood powder and the release characteristics of NOx precursors

Precipitation curves of NH3 and other nitrogen-containing compounds and K3PO4·3H2O during pyrolysis

Bing, Z. H. A. O., et al. Chemical Industry and Engineering Progress 37.03 (2018): 956.

The production of high-value-added chemicals by catalytic pyrolysis of biomass has broad application prospects, but the NOx emitted during the pyrolysis process will have an adverse impact on the environment. Thermogravimetric-mass spectrometry (TG-MS) was used to explore the pyrolysis characteristics of camphorwood powder and the release characteristics of the main NOx precursors during the pyrolysis process, and the effect of CaO-coupled phosphate on the reaction process of NOx precursor generation during the pyrolysis of camphorwood powder was compared and analyzed. The experimental results show that with the addition of potassium phosphate trihydrate and CaO, the release of volatile products during the pyrolysis of camphorwood powder increased and the yield of solid products decreased; at the same time, the ion current intensity curve of the main NOx precursors generated during the mixed pyrolysis process decreased. This shows that the coupling effect of potassium phosphate trihydrate and CaO can, on the one hand, improve the pyrolysis characteristics of camphorwood powder and make the pyrolysis process more thorough; on the other hand, it can effectively inhibit the primary cracking of nitrogen-containing compounds in camphorwood powder, delay the generation of NOx precursors such as NH3, and reduce the release of NOx precursors such as HCN.
The biomass used in the experiment was white camphor wood powder, which was dried at 105 °C under N2 atmosphere to constant weight before the experiment and sieved with a 90-mesh (less than 0.17 mm) standard sample sieve. The camphor wood powder was marked as sample 1. At the same time, camphor wood powder and CaO, camphor wood powder and potassium phosphate trihydrate, camphor wood powder, potassium phosphate trihydrate and CaO were mixed in mass ratios of 1:1, 1:1, and 1:1:1, respectively, and marked as sample 2, sample 3 and sample 4, and potassium phosphate trihydrate was marked as sample 5. During the experiment, the quality of camphor wood powder in each group of samples was ensured to be consistent. The connecting pipeline between TG and MS adopts gradient heating, that is, it is heated to 240℃, 260℃ and 280℃ respectively from the outlet of TG furnace to the inlet of MS instrument to prevent condensation of gas phase products; the experimental samples are placed in the aluminum oxide crucible of the thermogravimetric analyzer, and then high-purity argon gas with a purity of 99.999% is introduced to replace the air in the system, and the replacement is repeated 3 times. After the mass spectrometer signal is stable, the program temperature is started, and the mass spectrometer starts to record online. The argon flow rate is 50mL/min, the heating rate is 20℃/min, and the temperature range is 50~900℃. The experimental results have been normalized and corrected.

Recovery of biobutanol using potassium phosphate trihydrate

Acetone + 1-butanol + ethanol (ABE) fermentation has a long history but still faces the challenge of increasing low ABE concentrations to reduce production costs. Today, there is unprecedented interest in separation and purification techniques to recover ABE from fermentation broths. A simple salting-out procedure was developed for efficient extraction of ABE fermentation products from model solutions/fermentation broths by dissolving tripotassium phosphate trihydrate (K3PO4). Increasing the K3PO4 content allowed for liquid-liquid separation and enabled the recovery of ABE. The liquid-liquid equilibrium was determined primarily by the K3PO4 content and was less affected by temperature and the original solvent content. This was demonstrated by the correlation between the solubility of ABE and the molar concentration of K3PO4. More than 90 wt% of ABE was recovered from the model solution/fermentation broth and more than 99.75% of water was removed. This study provides a method to reduce the energy requirements of the subsequent distillation process for ABE purification.
The variable dilution feed used for the salting-out experiments can contain different concentrations of solvent (ABE). Two dilute model solutions were selected based on the typical composition of fermentation broths. Model solution A was used based on the typical approximate ratio of A:B:E = 3:6:1 ( / ). Model solution B is characterized by a higher total solvent concentration and a higher relative ethanol concentration. These model solutions are homogeneous due to the lower 1-butanol concentration and the co-solvents of acetone and ethanol. The acetone, 1-butanol, and ethanol contents of the fermentation broth were 0.39 wt%, 1.00 wt%, and 0.04 wt%, respectively. The butyric acid and acetic acid contents were neglected in this recovery study. Potassium phosphate trihydrate was dissolved in model solution A for phase separation. The initial aqueous concentration of K3PO4 in the salting-out system varied between 100 g/ kg and 650 g/ kg.
