Hydro-pyrolysis of lignocellulosic biomass over alumina supported Platinum, Mo

Songbo He, Jeffrey Boom, Rolf van der Gaast, K. Seshan

Frontiers of Chemical Science and Engineering 2018, Volume 12, Issue 1, Pages 155-161 doi: 10.1007/s11705-017-1655-x

Abstract: In-line hydro-treatment of bio-oil vapor from fast pyrolysis of lignocellulosic biomass (hydro-pyrolysis of biomass) is studied as a method of upgrading the liquefied bio-oil for a possible precursor to green fuels. The nobel metal (Pt) and non-noble metal catalysts (Mo C and WC) were compared at 500 °C and atmospheric pressure which are same as the reaction conditions for fast pyrolysis of biomass. Results indicated that under the pyrolysis conditions, the major components, such as acids and carbonyls, of the fast pyrolysis bio-oil can be completely and partially hydrogenated to form hydrocarbons, an ideal fossil fuel blend, in the hydro-treated bio-oil. The carbide catalysts perform equally well as the Pt catalyst regarding to the aliphatic and aromatic hydrocarbon formation (ca. 60%), showing the feasibility of using the cheap non-noble catalysts for hydro-pyrolysis of biomass.

Light olefins synthesis from С

Anton SHALYGIN, Evgenii PAUKSHTIS, Evgenii KOVALYOV, Bair BAL’ZHINIMAEV

Frontiers of Chemical Science and Engineering 2013, Volume 7, Issue 3, Pages 279-288 doi: 10.1007/s11705-013-1338-1

Abstract: A two-step process was employed to convert methane or ethane to light olefins via the formation of an intermediate monoalkyl halide. A novel K RuOCl /TiO catalyst was tested for the oxidative chlorination of methane and ethane. The catalyst had high selectivity for methyl and ethyl chlorides, 80% and 90%, respectively. During the oxychlorination of ethane at ≥250°C, the formation of ethylene as a reaction product along with ethyl chloride was observed. In situ Fourier transform infrared studies showed that the key intermediate for monoalkyl chloride and ethylene formation is the alkoxy group. The reaction mechanism for the oxidative chlorination of methane and ethane over the Ru-oxychloride catalyst was proposed. The novel fiber glass catalyst was also tested for the dehydrochlorination of alkyl chlorides to ethylene and propylene. Very high selectivities (up to 94%–98%) for ethylene and propylene formation as well as high stability were demonstrated.

Catalytic ozonation of organic compounds in water over the catalyst of RuO

Jianbing WANG,Guoqing WANG,Chunli YANG,Shaoxia YANG,Qing HUANG

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 4, Pages 615-624 doi: 10.1007/s11783-014-0706-5

Abstract: This research investigates the performances of RuO /ZrO -CeO in catalytic ozonation for water treatment. The results show that RuO /ZrO -CeO was active for the catalytic ozonation of oxalic acid and possessed higher stability than RuO /Al O and Ru/AC. In the catalytic ozonation of dimethyl phthalate (DMP), RuO /ZrO -CeO did not enhance the DMP degradation rate but significantly improved the total organic carbon (TOC) removal rate. The TOC removal in catalytic ozonation was 56% more than that in noncatalytic ozonation. However this does not mean the catalyst was very active because the contribution of catalysis to the overall TOC removal was only 30%. The adsorption of the intermediates on RuO /ZrO -CeO played an important role on the overall TOC removal while the adsorption of DMP on it was negligible. This adsorption difference was due to their different ozonation rates. In the catalytic ozonation of disinfection byproduct precursors with RuO /ZrO -CeO , the reductions of the haloacetic acid and trihalomethane formation potentials (HAAFPs and THMFPs) for the natural water samples were 38%–57% and 50%–64%, respectively. The catalyst significantly promoted the reduction of HAAFPs but insignificantly improved the reduction of THMFPs as ozone reacts fast with the THMs precursors. These results illustrate the good promise of RuO /ZrO -CeO in catalytic ozonation for water treatment.

Fabrication of ionic polymer-metal composites (IPMCs) and robot design

Hanmin PENG, Qingjun Ding, Huafeng LI

Frontiers of Mechanical Engineering 2009, Volume 4, Issue 3, Pages 332-338 doi: 10.1007/s11465-009-0046-5

Abstract: This paper describes a method for preliminary manufacturing experiments on a type of smart materials—ionic polymer-metal composites (IPMCs). They belong to EAP materials and are famous for their capability of huge displacement within a low voltage (1–3 V). With best operation quality in the humid environment, they can be made as underwater robots in simple structures. In this paper, two purposes are embodied. One focuses on the research on the IPMCs characteristics, including the actuating principle, manufacturing process, and parameters of performance. The other is that a relevant robot driven by IPMCs strips is designed. According to imitation propulsion mechanism of undulatory fins, IPMCs are designed for a novel bionic water vehicle propelled by undulatory multiple fish-like fins (made by IPMCs). The robot consists of three fins on the bottom tightly contacting by plastic foils with each other.
