Foundry Coke

The Use of Metallurgical Coke as Carburizing Material in the Foundry

Original scientific paper The properties of metallurgical cokes obtained in a laboratory from pure coal and with additives (light atmospheric residue of oil distillation and coal tar pitch) after heat treatment to 1600 °C were investigated. Changes in the basic characteristics (density, moisture, ash, metal and sulphur contents) were examined. Crystallographic parameters (crystallite size, Lc a...

When Coke Is Not Hydrating

A 47-year-old African American man was admitted with 4 days of back pain, nausea and vomiting, and low urine output. There was no history of fever, dysuria, frequency, hesitancy, viral symptoms, trauma, rash, or constipation. Despite his past medical history of hypertension, diabetes mellitus, and hyperlipidemia he denied taking any medications for 18 months, including nonsteroidal anti-inflamm...

Enhanced Foundry Production Control

Mechanical properties are the attributes that measure the faculty of a metal to withstand several loads and tensions. Specifically, ultimate tensile strength is the force a material can resist until it breaks and, thus, it is one of the variables to control in the foundry process. The only way to examine this feature is the use of destructive inspections that renders the casting invalid with th...

Coke Inhibition During Naphtha Pyrolysis

Regeneration performance and carbon consumption of semi-coke and activated coke for SO₂ and NO removal.

To decrease the operating cost of flue gas purification technologies based on carbon-based materials, the adsorption and regeneration performance of low-price semi-coke and activated coke were compared for SO2 and NO removal in a simulated flue gas. The functional groups of the two adsorbents before and after regeneration were characterized by a Fourier transform infrared (FTIR) spectrometer, a...
