Atmospheric Photolytic Reduction of Hg(II) in Dry Aerosols

14-Aug-2013 | Yindong Tong; Terry Eichhorst; Michael R Olson; Jerome E McGinnis; Isabel Turner; Andrew P Rutter; Martin Shafer; Xu ..., Journal of Environmental Monitoring, 2013

A laboratory reactor system was developed to examine the role of light and aerosol composition on the reduction of oxidized mercury (Hg(II)) in laboratory-generated aerosols. Aerosolized sodium chloride, doped with mercury chloride, was exposed to light in a fixed-bed flow-through reactor. Three ...

Kinetics of o‐Xylene Combustion over a Pt/Alumina Catalyst

01-Nov-2012 | C. M. Manta, G. Bozga, G. Bercaru, C. S. Bîldea, Chemical Engineering & Technology, 2012

Abstract o‐Xylene combustion in air over a Pt/γ‐Al2O3 catalyst was investigated in a laboratory reactor at low concentrations typical for depollution applications. The results evidenced a slightly negative influence of o‐xylene concentration on combustion rate. A kinetic model of the ...

Process evaluation of the gasification of leningrad oil shale

15-Aug-2012 | Yu. A. Strizhakova, N. Ch. Movsum-Zade, T. A. Avakyan, T. V. Usova, Solid Fuel Chemistry, 2012

The results of experiments on the thermal processing of Leningrad oil shale in a laboratory reactor under the conditions of rapid heating (50 K/min) from 20 to 500, 550, 600, and 650°C in the flow of steam. The results were mathematically evaluated using a recirculation method.

Atmospheric Pressure Low Temperature Direct Plasma Technology: Status and Challenges for Thin Film Deposition

07-Aug-2012 | Francoise Massines, Christian Sarra‐Bournet, Fiorenza Fanelli, Nicolas Naudé, Nicolas Gherardi, Plasma Processes and Polymers, 2012

Abstract Over the last ten years, expansion of atmospheric pressure plasma solutions for surface treatment of materials has been remarkable, however direct plasma technology for thin film deposition needs still great effort. The objective of this paper is to establish the state of the art on ...

Hydrogen production via solar‐aided water splitting thermochemical cycles with nickel ferrite: Experiments and modeling

27-Jun-2012 | Christos Agrafiotis, Alexandra Zygogianni, Chrysoula Pagkoura, Margaritis Kostoglou, Athanasios G. Konstandopoulos, AIChE Journal, 2012

Abstract Water splitting – thermal reduction cyclic studies with NiFe2O4redox materials were performed in a differential fixed bed laboratory reactor in the temperature range 700‐1400°C to quantify the effects of operation temperatures and steam mole fraction on hydrogen and oxygen yields. ...

Quantification of polyethylene wax in semibatch laboratory reactor and a study of different parameters on wax production as a by‐product in the slurry ethylene polymerization

09-May-2012 | Bayat, Mohammad Hossein; Abdouss, Majid; Javanbakht, Mehran, Journal of Applied Polymer Science, 2012

Abstract In coordination polymerization of alpha‐olefins utilizing Ziegler‐Natta catalysts via slurry, polyolefin is produced with other by‐products such as polyethylene wax. Wax is defined as a linear short chain saturated by hydrocarbons in the relevant industries. Hexane and heptane are two ...

Photocatalysis for Continuous Air Purification in Wastewater Treatment Plants: From Lab to Reality

05-Apr-2012 | R. Portela; R.F. Tessinari; S. Suárez; S.B. Rasmussen; M.D. Hernández-Alonso; M.C. Canela; P. Ávila; B. Sánchez, Environmental Science & Technology, 2012

The photocatalytic efficiency of TiO2–SiMgOx plates to oxidize H2S was first evaluated in a flat laboratory reactor with 50 mL min–1 synthetic air containing 100 ppm H2S in the presence of humidity. The use of the photocatalyst-adsorbent hybrid material enhanced the photocatalytic activity in ...

Experimental Investigation of Initial Coke Formation over Stainless Steel, Chromium, and Iron in Thermal Cracking of Ethane with Hydrogen Sulfide as an Additive

06-Sep-2011 | Seyed Mahdi Jazayeri; Ramin Karimzadeh, Energy & Fuels, 2011

The effect of injection of hydrogen sulfide, an available inexpensive byproduct in Iran’s petrochemical industry, on the rate of coke formation over chromium, iron, and stainless-steel (SS) coupons in thermal cracking of ethane was investigated. In a laboratory reactor, coke formation on the ...

Feasibility of Tubular Microreactors for Emulsion Polymerization

07-Jan-2011 | Yadav, Arvind Kumar; de la Cal, José Carlos; Barandiaran, María Jesús, Macromolecular Reaction Engineering, 2011

Abstract The viability of a tubular microreactor for the production of polymer dispersions by emulsion polymerization was investigated. The reactor setup and operational conditions necessary to reach a very stable reactor operation were determined. It was found that stability of pre‐emulsion ...

Mild hydrotreating of biomass pyrolysis oils to produce a suitable refinery feedstock

01-Jul-2010 | French, Richard J.; Hrdlicka, Jason; Baldwin, Robert, Environmental Progress, 2010

Fast pyrolysis produces a liquid product that represents ∼70% of the mass of the starting material. However, since the raw oil is highly corrosive, largely immiscible with hydrocarbons, and only partly volatile, it is unsuitable for use in a conventional petroleum refinery or as a finished fuel. ...
