The highlight of the event was when the Coke Ambassadors, together with key Coke representatives in each venue, poured buckets of ice in the coolers – which made the temperature drop to 3˚ Celsius. It was a eureka moment as the audience realized that the key to getting the perfect Coke...
precursors that can readily evolve to polycyclic aromatic hydrocarbons (PAHs), the typical coke species, through cyclization17and cross-linked mechanism18,19, accelerating catalyst deactivation20. Therefore, such dual-role of HCPs impedes achieving superior light olefins selectivity while maintaining long c...

Because of high redox potential (2.5–3.1 V), strong selectivity, and flexibility of pH tolerance, PS can be used as an important substitute for H2O2 system. For PS-based AOPs, SO4•− is mainly generated by activating peroxymonosulfate or PS [18] via light radiation [19], heat [20...
A light optical microscope (LOM, Nikon ECLIPSE E600 POL, Tokyo, Japan) was used for studies of textures in bio-coal, coke and bio-cokes. The samples were mounted in epoxy resin, and the surface was polished, before studies in LOM. The chemical composition of coke was analyzed by SSAB Lu...
The liquid output of the flash separator consists mainly of condensed water, methanol, and solubilized compounds due to the high pressure, while the recycled gas stream mainly contains light compounds (CO, CO2, H2, N2). A second flash separator under a pressure of 2 bar is used to separate...
The key problem of butene catalytic cracking is the proper design of the catalyst. Zeolite is the most widely used type of catalyst. However, in the reaction process, its fast deactivation remains an urgent problem. Therefore, research on the catalyst deactivation mechanism of light olefins catalyt...
