Development and field testing of a miniaturized sampling system for simultaneous sampling of vapours and droplets

16.12.2014 | Dietmar Breuer; George C. Dragan; Claudia Friedrich; Carsten Möhlmann; Ralf Zimmermann, Journal of Environmental Monitoring, 2014

The sampling of semi volatiles (SV) in workplaces may lead to different results as measurements may be affected by sampling bias. The new European Standard EN 13936 defines “semi-volatiles” as substances with vapour pressures in the range between 0.001 and 100 Pa at room temperature. EN 13936 ...

Catalytic reforming of acetic acid as a model compound of bio‐oil for hydrogen production over Ni‐CeO2‐MgO/olivine catalysts

11.12.2014 | Xingmin Xu, Changsen Zhang, Yonggang Liu, Yunpu Zhai, Ruiqin Zhang, Xiaoyan Tang, Environmental Progress, 2014

Olivine was used as a support with CeO2/MgO as promoters to synthesize a series of Ni‐based catalysts by wet impregnation for reforming acetic acid as a model compound of bio‐oil for H2 production. These catalysts were characterized by X‐ray diffraction, N2 physisorption, and scanning electron ...

KF‐impregnated clam shells for biodiesel production and its effect on a diesel engine performance and emission characteristics

11.12.2014 | Subramaniapillai Niju, Muhammed Niyas, Kader Mohamed Meera Sheriffa Begum, Narayanan Anantharaman, Environmental Progress, 2014

Natural white bivalve clam shells were calcined to obtain calcium oxide (CaO) and KF/CaO catalyst was synthesized by impregnating potassium fluoride (KF) on calcined clam shells. This solid catalyst was tested for transesterification of waste frying oil. A high biodiesel yield of 95.77% was ...

Foam Mat Drying of Food Materials: A Review

11.12.2014 | Sangamithra A, Sivakumar Venkatachalam, Swamy Gabriela John, Kannan Kuppuswamy, Journal of Food Processing and Preservation, 2014

Abstract Foam mat drying is an economical alternative to drum, spray and freeze‐drying for the production of food powders. The liquid is whipped to form stable foam, and dehydrated by thermal means. The larger surface area of the foam accelerated the drying process for the rapid moisture ...
