UOP 822 – Specific Gravity of Coke and Powdered Asphalts
This method is for determining the specific gravity of coke derived from either petroleum or coal. Other granular materials can be analyzed if they can be ground to pass a No. 200 sieve, are essentially insoluble in ethylene glycol and have a specific gravity greater than ethylene glycol. The method is also applicable to hard asphalts and similar materials that can be ground to pass through a No. 100 sieve and are essentially insoluble in tert-amyl alcohol.
