the purpose of this study is the utilization of furfural residue for heating energy and activated carbon production. to evaluate the energy production of the residue, bulk density, melting point, and heating value were measured. furthermore, moisture, ash, volatile compounds, fixed carbon, lignin, and elements were determined. ash and volatile content average were measured at 15.4% and 68.9%, r...

In the present work, the in¯uence of the nucleation time-lag on the non-isothermal glass crystallization is discussed. Di€erential thermal analysis (DTA) results of an iron-rich glass nucleated by Cr 2 O 3 were obtained at di€erent heating rates. The activation energy of crystallization, E c , and the Avrami parameter, m, estimated by Kissinger's and Ozawa's equations were shown to be dependent...

the present study attempts to investigate the effect of thermal treatment at 180 °c for 8 hours on chemical changes, quality indexes and oxidative stability of three iranian common virgin olive oils (zard, mari and phishomi). oil samples were taken every 2h of heating treatment and assessed for fatty acid composition, conjugated diene value, carbonyl value, color index and oxidative stability i...

Direct electron heating of compact ignition devices by radio-frequency power OSTI Abstract. in the 300-400 MHz,range is discussed. The possible advantage of this approach to heating an ignition device, as opposed to resonant heating of an ion population, is the insensitivity to the exact value of the magnitude field. Heating with central power deposition during a toroidal field ramp is therefor...

In this paper, a new power, heating and hydrogen cogeneration cycle from Sabalan geothermal two wells is proposed and analyzed. In the proposed system, a new double flash cycle and organic Rankine cycle are used for power production. A proton exchange membrane (PEM) is also used for hydrogen production and the domestic water heater is used for heating. The impacts of some design parameters, suc...

Chemical degradation of edible oils has been studied using conventional spectroscopic methods spanning the spectrum from ultraviolet to mid-IR. However, the possibility of morphological changes of oil molecules that can be detected at terahertz frequencies is beginning to receive some attention. Furthermore, the rapidly decreasing cost of this technology and its capability for convenient, in si...

Introduction: Paterae on Io are similar to calderas on the Earth and other planets, yet they have some differences, such as their great sizes (from 2 to 206 km diameter) and lack of high edifices. Tidal heating from Jupiter leads to the production of molten material and the eruption of large amounts of mafic to ultramafic lava within Io’s paterae, as well as across its surface. Formation of pat...

abstract: the history of food science, technology and nutrition and their expansion in respect of raw material, processing, finished products and nutritional value goes back to many years and is still the interests of many researchers. in this work ascorbic acid has been taken not only as an important and vital vitamin to be investigated during the course of different heat processes but also as...
