    catalysts Review Transition Metal Phosphides for the Catalytic Hydrodeoxygenation of Waste Oils into Green Diesel M. Consuelo Alvarez-Galvan * , Jose M. Campos-Martin * and Jose L. G. Fierro * Energy and Sustainable Chemistry Group (EQS), Instituto de Catálisis y Petroleoquímica, CSIC, c/Marie Curie, 2 Cantoblanco, 28049 Madrid, Spain * Correspondence: [email protected] (M.C.A.-G.); [email protected] (J.M.C.-M.); jlgfi[email protected] (J.L.G.F.) Received: 28 February 2019; Accepted: 15 March 2019; Published: 22 March 2019 Abstract: Recently, catalysts based on transition metal phosphides (TMPs) have attracted increasing interest for their use in hydrodeoxygenation (HDO) processes destined to synthesize biofuels (green or renewable diesel) from waste vegetable oils and fats (known as hydrotreated vegetable oils (HVO)), or from bio-oils. This fossil-free diesel product is produced completely from renewable raw materials with exceptional quality. These efficient HDO catalysts present electronic properties similar to noble metals, are cost-efficient, and are more stable and resistant to the presence of water than other classical catalytic formulations used for hydrotreatment reactions based on transition metal sulfides, but they do not require the continuous supply of a sulfide source. TMPs develop a bifunctional character (metallic and acidic) and present tunable catalytic properties related to the metal type, phosphorous-metal ratio, support nature, texture properties, and so on. Here, the recent progress in TMP-based catalysts for HDO of waste oils is reviewed. First, the use of TMPs in catalysis is addressed; then, the general aspects of green diesel (from bio-oils or from waste vegetable oils and fats) production by HDO of nonedible oil compounds are presented; and, finally, we attempt to describe the main advances in the development of catalysts based on TMPs for HDO, with an emphasis on the influence of the nature of active phases and effects of phosphorous, promoters, and preparation methods on reactivity.

The information in the summary is basic information and is not intended to provide emergency response information, medical information or treatment information. The summary should not be used to provide in-depth safety and health information. In-depth safety and health information can be found in the Safety Data Sheet (SDS) for the chemical substance. Names Fluorosilicic acid (FSA) Hexafluorosilicic acid (HFA or HFS) Sand acid Silicate(2-), hexafluoro- hydrogen (1:2) Silicofluoride Fluosilicic acid Hydroflurosilicic acid Silicofluoric acid Silicon hexafluoride dihydride Silicate(2-), hexafluoro-, dihydrogen Product Overview Solvay Fluorides, LLC does not sell fluorosilicic acid solutions directly to consumers. Most fluorosilicic acid is used in industrial or municipal applications/processes. Concentrated fluorosilicic acid solution (FSA) is used for water fluoridation, as a metal surface treatment and cleaner and for pH adjustment in industrial textile processing or laundries. It can also be used in the processing of hides, for hardening masonry and ceramics and in the manufacture of other chemicals. FSA can only exist as a liquid. There is no solid form. Fluorosilicic acid solutions are corrosive and contact can severely irritate and burn the skin and eyes causing possible permanent eye damage. Breathing concentrated fluorosilicic acid solutions can severely irritate and burn the nose, throat, and lungs, causing nosebleeds, cough, wheezing and shortness of breath. Many of the symptoms described are due to the hydrogen fluoride present as an impurity. Page 1 of 7 Copyright 2010-2013, Solvay America, Inc.

  • PRODUCTION of ELECTRONIC GRADE LUNAR SILICON by DISPROPORTIONATION of SILICON DIFLUORIDE, William N
    PRODUCTION OF ELECTRONIC GRADE LUNAR SILICON BY DISPROPORTIONATION OF SILICON DIFLUORIDE, William N. Agosto, Lunar Industries, P.O. Box 590004, Houston, TX 77259-0004 Waldron (1) has proposed to extract lunar silicon by sodium reduction of sodium fluorosilicate derived from reacting sodium fluoride with lunar silicon tetrafluoride. Silicon tetrafluoride is obtained by the action of hydrofluoric acid on lunar silicates. While these reactions are well understood, the resulting lunar silicon is not likely to meet electronic specifications of 5 nines purity. Dale and Margrave (2) have shown that silicon difluoride can be obtained by the action of silicon tetrafluoride on elemental silicon at elevated temperatures (1100-1200 C) and low pressures (1-2 torr). The resulting silicon difluoride will then spontaneously disproportionate into hyperpure silicon and silicon tetrafluoride in vacuum at approximately 400 C. On its own merits, silicon difluoride polymerizes into a tough waxy solid in the temperature range from liquid nitrogen to about 100 C. It is the silicon analog of teflon. Silicon difluoride ignites in moist air but is stable under lunar surface conditions and may prove to be a valuable industrial material that is largely lunar derived for lunar surface applications. The most effective driver for lunar industrialization may be the prospects for industrial space solar power systems in orbit or on the moon that are built with lunar materials. Such systems would require large quantities of electronic grade silicon or compound semiconductors for photovoltaics and electronic controls. Since silicon is the most abundant semimetal in the silicate portion of any solar system rock (approximately 20 wt%), lunar silicon production is bound to be an important process in such a solar power project.

  • Airway Nitrite Is Increased in Extremely Preterm Infants with Bronchopulmonary Dysplasia Samuel J
    Gentle et al. Respiratory Research (2020) 21:244 https://doi.org/10.1186/s12931-020-01508-8 LETTER TO THE EDITOR Open Access Airway nitrite is increased in extremely preterm infants with bronchopulmonary dysplasia Samuel J. Gentle1* , Amelia Freeman1, Rakesh P. Patel2, Namasivayam Ambalavanan1 and Charitharth V. Lal1 Abstract Rationale: Bronchopulmonary dysplasia (BPD) is the most common complication of prematurity and significantly contributes to mortality and morbidity with few predictive biomarkers. Given that nitrites have been implicated in pathways associated with lung disease, we hypothesized that nitrite levels would be altered in the airways of premature infants diagnosed with BPD. Methods: This was a prospective cohort study of extremely low birth infants (< 28 weeks’ gestation) at the University of Alabama at Birmingham. Nitrite levels from tracheal aspirates (TAs) were compared between intubated and ventilated infants with BPD and gestation matched full term (FT) controls. TA derived nitrite levels from day one after birth were also compared between preterm infants who did and did not develop BPD. Results: Infants with BPD were found to have significantly elevated nitrite levels in their tracheal aspirates compared to gestation matched FT controls (p < 0.05). There was a trend for increased nitrite levels on postnatal day one in infants that developed BPD compared to infants that did not develop BPD (p = 0.05). Conclusions: In conclusion, nitrite levels are significantly increased in airways of infants with BPD. Data from a larger cohort are needed to further support the utility of nitrite for BPD prediction. Trial registration: Not applicable. Keywords: Bronchopulmonary dysplasia, Preterm infants, Nitrite, Nitric oxide Introduction Nitric oxide a signaling molecule produced throughout Bronchopulmonary dysplasia (BPD) is a common morbid- the airway, has many physiologic roles in the lung in- ity of preterm infants for which few biomarkers exist.
