Abstract
Low-quality sulfur petroleum coke usually not widely qualified for use and is stockpiled at refineries around the world or used as solid fuel. One of the promising uses of low-quality petroleum coke is its physical or chemical activation in order to obtain a highly porous carbon material that can be used as a catalyst carrier, adsorbent, the basis for capacitive electrodes. In this work, four types of hydrocarbon which differ in origin, group hydrocarbon composition and properties, were used for petroleum coke production (vacuum residue, asphalt, heavy catalytic gasoil, heavy shale oil). In order to experimentally simulate the process of coke production was used a laboratory delayed coking unit with varying process parameters from 1.5 to 3.5 atmg at a temperature of 500 °C. The produced coke was subjected to chemical activation with KOH at 750 °C. Regularities of changes in the composition, structure and properties of coke produced with the examined raw materials at the typical regime parameters of the coking process during activation were studied by XRF, SEM, FT-IR spectroscopy, BET. It was shown that after activation the crystallinity of the coke and the mass of sulfur in the samples decreases, but increases the content of potassium. The largest surface area of 2302 m2/g and porosity 83% was obtained when using coke from vacuum residue at 1.5 atmg as a carbon feedstock for the activation process. In order to obtain a highly porous material it is necessary to use raw materials with less aromatic compounds, but containing comparable amounts of resins and saturated hydrocarbons.
