“…A more comprehensive understanding of the impact that the chemical composition of direct liquefaction biocrudes has on upgrading is becoming possible as more advanced methods are developed for characterizing biocrudes and the hydrotreated biocrude products. ,− Correlating the oxygen content of direct liquefaction intermediates with biocrude upgrading performance can be extended to evaluating the impact of individual components with specific oxygen functionality on the performance of hydrotreating catalysts. The various pyrolysis technologies being developed produce biocrude intermediates with a wide range of oxygen contents that depend on the catalyst, process conditions (temperature, pressure, hydrogen partial pressure), and feedstock. , …”

This study investigates hydrotreating biocrude produced by reactive catalytic fast pyrolysis (RCFP), a direct biomass liquefaction process that combines a robust hydrodeoxygenation catalyst for in situ pyrolysis with excess hydrogen at ambient (low) pressure. The RCFP process leverages advantages from catalytic fast pyrolysis (process simplicity and improved biocrude quality) and biomass hydropyrolysis (enhanced hydrodeoxygenation) to produce a thermally stable biocrude that can be upgraded in a single hydroprocessing step or coprocessed with petroleum refining intermediates to produce gasoline- and diesel-range hydrocarbons. RCFP biocrude (9.4 kg, 19.3 wt % oxygen, dry basis) was hydrotreated continuously for 144 h, in a pilot-scale hydroprocessing unit, at 138 barg (2000 psig) hydrogen pressure, 0.31 h–1 space velocity, and an average temperature of 300 °C. Blends of 10%, 15%, and 20% RCFP biocrude in light gas oil were also upgraded over a NiMo hydrotreating catalyst at 350 °C in hydrogen at 50–70 barg (725–1015 psig). The stand-alone hydrotreating results indicate that, even though there was no pressure drop increase indicative of reactor fouling, hydrotreating catalyst deactivation was evident as the product density increased from 0.852 to 0.955 kg/L after 144 h time-on-stream. Additionally, the oxygen content of the upgraded liquid product increased from 1.4 wt % to 5.5 wt % over the course of the experiment. In the coprocessing test, little or no catalyst deactivation was observed with the 10% RCFP blend on the basis of the density of the hydrotreated products. However, the hydrotreating catalyst activity was lower during upgrading of the 20% and 15% blends. On the basis of hydrodesulfurization of light gas oil, the relative activity of the hydrotreating catalyst decreased by 40% during the 1000 h coprocessing test. Fortunately, this level of deactivation measured at this small scale does not correlate to a prohibitively large deactivation rate at the industrial scale.

“…Analysis was achieved using ICP-MS with an assortment of internal standards introduced as a mixture on-line rather than being spiked into individual samples. The internal standards used were 45 Sc for those elements with a mass up to and including 59 Co, 72 Ge for the analytes 62 Ni to 95 Mo, 125 Te for 101 Ru to 137 Ba, 175 Lu for the analytes 189 Os to 197 Au and 209 Bi for analytes with a higher mass. Any polyatomic interferences were removed through the introduction of helium at a ow rate of 5 mL min −1 into the collision/reaction chamber.…”

“…282 The sample and LAMP reagents were mixed and encapsulated in agarose droplets, generated by inhouse fabricated centrifugal droplet generators, and only agarose particles, containing virus DNA were labelled with Ru compound. The copy number of virus DNA was estimated from the 101 Ru : 153 Eu ratio detected using SV-ICP-MS. The lowest quantication achieved was 25 copy per mL virus DNA in one analysis without the need for a calibration curve.…”

Background Pyroligneous acid (PA) is an aqueous smoky fraction produced during pyrolysis of biomass. The chemical composition of PA from different plant biomass has been studied, but reports on PA metabolites and elemental profiles are rare. In this study, we examined the metabolites, elemental profiles and the associated chemical activities of PA derived from white pine (Pinus strobus) at 1100 °C compared to similar work done elsewhere using different biomass at lower temperatures. Results PA from P. strobus biomass exhibited a lower electrical conductivity (2.05 mS/cm), salinity (1.03 g/L) and total dissolved solids (1.42 g/L) but higher oBrix content (9.35 ± 0.06) compared to PA from other feedstock. The P. strobus PA showed a higher antioxidant activity characterized by enhanced radical scavenging activity against 1,1-diphenyl-2-picrylhydrazyl free-radical (78.52%) and accumulation of higher total phenolic (95.81 ± 1.45 gallic acid equivalents (GAE)/mL) and flavonoid content (49.46 µg quercetin/mL). Metabolite profiling by direct injection mass spectrometry with a reverse-phase liquid chromatography–mass spectrometry (DI/LC–MS/MS) identified a total of 156 metabolites. Four (4) main groups including organic acids (90.87%), hexose (8.60%), carnitine (0.3%) and phospholipids (0.24%) were found in the PA. Mineral element analysis revealed that the P. strobus PA contained high concentrations of nitrogen (N), potassium (K), calcium (Ca) and zinc (Zn), while the content of sodium (Na) and trace/heavy metals were present at levels below the reported limit. Conclusion This study indicates that P. strobus PA is a valuable product that can be used in agriculture to improve plant growth and productivity under normal and environmentally stressful conditions.
