Some effects of carbonation on keeping qualities, flavor, and sanitary quality of dairy products
Milk and even cream were carbonated during the following processes: separation, pasteurization and during storage. Solid and gaseous carbon dioxide were used in these treatments. Untreated milk and cream were processed and stored as checks. Various methods of carbonation were employed. The …

The formation of carbon nanofibers and thin films from the catalytic decomposition of ethylene by palladium
… an exceptional catalyst toward the deposition of solid carbon from ethylene in two distinct forms: nanofibers and thin films. Four forms of palladium were tested: sputtered film, foil, sub-micron powder, and nanopowder. The deposition of carbon can be achieved by a very simple method. In this …

Simulation of Combustion and Thermal-flow Inside a Pyroscrubber
… coke calcining process is to oxidize the carbonaceous contents, including hydrocarbon volatiles, of the exhaust gas from the calcination kiln, so as to leave no more than small traces of unburned volatiles, solid carbon, ashes, or emissions (e.g. CO, NOx and SOx) in the flue gas finally …

Selective area synthesis of 3-D carbon nanotube forest microsctructures
… THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Carbon nanotubes (CNTs) are solid carbon allotropes that feature high strength and high transport capabilities. When large populations of CNTs are synthesized simultaneously, they self-assemble into vertically oriented CNT forests (also called CNT …

Selective thermal transformation of e-waste to novel metallic alloys
… the nanoparticles from oxidation, while solid carbon minimized agglomeration. Also, two step heat treatment approach has been investigated to remove the toxic and low melting point elements first and then go to high temperature and produce Cu-based alloys without toxic elements. Results …

Reduction of greenhouse gas emissions using the sustainable systems-thinking approach by utilizing cost-effective hydrogen production with a lower environmental footprint
… clean Hydrogen (without CO₂ emissions) and Solid Carbon. For Hydrogen demand, eXtremOS simulation model was used to forecast European socio-technical energy system scenarios and clean energy transformation pathways. The forecasted H₂ demand was used as an input assumption for the simple …

Feasibility study to extract iron and chromium from chromium contaminated soils
… rapid at temperature higher than 1100 C. The solid carbon was used as a reducing agent for the study of reduction in Thermo-Gravimetric Analyzer. The reduction process was found to be controlled by gasification with the activation energy of 45-55 kcal/mol based on the selected kinetic models. …

An Experimental Investigation of the Role of Small Hydrocarbons and Combustion-Generated Nanoparticles on the Formation and Growth Reactions of Polycyclic Aromatic Hydrocarbons during the Pyrolysis of a Model-Fuel and Hydrocarbon Gases
<p align = "justify">Polycyclic aromatic hydrocarbons (PAH) are an important class of environmental pollutants formed during fuel combustion or pyrolysis. Therefore, an experimental study has been undertaken to better understand the formation and growth pathways of PAH.</p> <p align = "justify">To …

Biomass gasification in small scale plants: experimental and modelling analysis
… whenever possible, direct combustion of solid biomass and, rather, pursuing fuel upgrade processes allowing a better combustion or direct conversion to electricity through fuel cells. The products originating from the gasification process mainly comprise a mixture of the permanent gases …

Reduction and softening/melting behaviour of olivine pellet in the experimental blast furnace
… a higher melting point. From the analysis of carbon contents of the excavated pellets in cohesive zone, it was observed that the carburization of iron pellets began after the complete reduction. This study has established that the reduction rate of iron pellet is the rate controlling step for …

Electrical current generation by wild type and mutant Shewanella strains
… of electrons to insoluble metal oxides and solid carbon electrodes with cellular growth. While this process may be useful as an energy generation strategy or biotechnological tool, the electron transfer pathway by which this process occurs is not completely understood, and better techniques …
