Large scale production of multi-walled carbon nanotubes by fluidized bed catalytic chemical vapor deposition : a parametric study [PDF]
A parametric study investigating the impact of temperature, run duration, total pressure, and composition of the gaseous phase on the catalytic growth of multi-walled carbon nanotubes (MWNT) has been performed.

Recycling Of Carbone Oxides (Co, Co2) Conversion Into Methanol At Atmospheric Pressure Over Mechanochemical Achtivated Cuo-zno-al2o3 Catalyst [PDF]
The catalytic process for methanol production by synthesis gas conversion under the conditions of mechanochemical activation (MCA) of copper-zinc-aluminum oxide catalyst in the temperature range 160–280 °C at a pressure of 0.1 MPa are investigated.

Cyclones are endured, but often dreaded in tropical regions such as Far North Queensland. Memories, and often myth, of their destructive effects permeate written, visual and spoken text from and about this area. This paper presents findings from a qualitative research project which examined the impact of tropical north Queensland’s 2006 Cyclone Larry ...

Selective hydrogenation in trickle-bed reactor. Experimental and modelling including partial wetting. [PDF]
A steady state model of a trickle bed reactor is developed for the consecutive hydrogenation of 1,5,9-cyclododecatriene on a Pd/Al2O3 catalyst. Various experiments have shown that the selectivity of this reaction towards the product of interest is much ...

Integration as a catalyst for assimilation [PDF]
We draw a distinction between the social integration and economic assimilation of migrants, and study an interaction between the two. We define social integration as blending into the host country’s society, and economic assimilation as acquisition of human capital that is specific to the host country’s labor market.

Characterization of a new iron-on-zeolite Y Fischer-Tropsch catalyst [PDF]
Iron pentacarbonyl adsorbed on dry Na-Y zeolite can be oxidized at subambient temperatures into Fe203 located in the zeolite supercages (catalyst I). When catalyst I is hydrogen reduced at 575 K most of the iron has agglomerated externally to the zeolite

Diffusion and catalyst efficiency in hierarchical zeolite catalysts
Abstract The preparation of hierarchical zeolites with reduced diffusion limitation and enhanced catalyst efficiency has become a vital focus in the field of zeolites and porous materials chemistry within the past decades. This review will focus on the diffusion and catalyst efficiency of hierarchical zeolites and industrial catalysts ...

Structural behaviour of copper chloride catalysts during the chlorination of CO to phosgene [PDF]
The interaction of CO with an attapulgite-supported Cu(II)Cl2 catalyst has been examined in a micro-reactor arrangement. CO exposure to the dried, as-received catalyst at elevated temperatures leads to the formation of CO2 as the only identifiable ...
