【Alkylation】Alkylated gasoline

This post was last edited by Xiao Gong 1985 on 2016-3-4 08:49. Nowadays, in addition to sulfuric acid and hydrofluoric acid being used as catalysts for alkylated gasoline, it is said that solid acid catalysis is now also in use. Does anyone know what kind of catalysts are employed in solid acid catalysis?
I really don’t know about this; you can check online. Solid acids aren’t yet very mature, so it’s advised not to consider them.
I heard that some manufacturers in Shandong have already adopted this technology; I’m not sure what catalysts are being used, and I’d like to find out
Acidic platinum catalysts eliminate the need for sulfuric acid, making them highly environmentally friendly! !
Do you know which catalyst the PT is loaded on? Is it from the ZSM series? Do you know the specific model?
Could you give a general explanation of this catalyst?
Foreign catalysts include BF3/Al2O3, SbF5/SiS2, CF3-HSO3/SiO2, etc.
I’ve heard about it too; there are solid acids available now, but I don’t know much about them in detail. Another option is ionic liquids, which also do not involve acid consumption.
There are solid acid catalysts, but very few have been industrialized; it seems none exist in China either. Solid acids are primarily used as the catalytic component, and sometimes Pt is added to facilitate catalyst regeneration. The main problem is that the catalyst needs to be regenerated frequently, and its performance is slightly inferior to that of liquid acids. Ion liquids from the Petroleum University have also been introduced in Shandong; they require less catalyst, but ion liquids are extremely expensive ； Secondly, it is said that the energy consumption might be a bit higher.
Recently, KBR announced that it had signed a transfer agreement with Dongying Haikelerlin Chemical Co., Ltd. regarding its K-SAAT solid acid alkylation technology; this marks the first time that this technology has received recognition in China. It is reported that the K-SAAT solid acid alkylation technology is a safe and revolutionary method for producing alkylated oils, which are the cleanest and highest-quality components used in gasoline blending. Unlike the alkylation processes traditionally used in refineries, which rely on strong acids, the K-SAAT solid acid alkylation technology utilizes safer and more environmentally friendly solid catalysts to convert low-carbon olefins and isobutane into high-quality alkylated oils.
