High Temperature Solid Acid Alkylation
Thread Content
This post was last edited by Chen Wentao on 2016-11-11 13:17 Domestic independent high-temperature solid acid alkylation pilot phase has begun. With a super luxury lineup, the door to a new era of alkylation has been opened. Pay tribute to the frontline researchers engaged in the research and development of solid acid alkylation technology. This pilot test is not a fixed bed yet. . . . A new page has been turned, what is the effect? Will it break the monopoly of the sulfuric acid process? Let’s wait and see! According to the information summary, there are 13 sets of solid acids, plus those who are investigating projects and want to solid acid alkylation. There are quite a lot of them at present. The investment is not low. It has not been localized yet. The catalyst needs to be imported. Currently, Lanzhou Global is responsible for the translation of the KBR process package of Haike Petrochemical. Currently, the project is being followed up. The cost is too high. Is there any legendary low operating cost? We still need to make reference to the actual operating cost of Haike Petrochemical. Wanting to localize it is useless without a catalyst. We look forward to localizing the catalyst. Zhida’s version is called low-temperature sulfuric acid alkylation, so should Lanzhou Global’s version be called medium-high temperature solid acid alkylation?
I wish you success in research and development, and great economic and social benefits.
I wish you complete success, great economic and social benefits.
From my personal point of view, it is still a bit difficult. Since the 1990s, there have been high hopes for solid acid replacement of sulfuric acid alkylation, but with little success for such a long time, it seems that it is not that simple.
The key is that the first set of foreign versions has been released, and if there is a catalyst, it can be imitated and manufactured. Besides, domestic refinement is still very good in this area. On a corresponding basis, the performance may be even better! For example, the ammonia synthesis catalyst is also the second generation introduced and developed from abroad, not to mention it is superior to similar foreign products.

I don’t know what the alkylation process in Zhejiang Zhoushang is, but I know it is 450,000 tons of alkylation.
You are right about this. Solid acid alkylation is indeed difficult, and it did not start in the 1990s. The earliest zeolite-catalyzed carbon tetraalkylation literature I have read is from 1968, and there may be even earlier patents. Solid acids that are not zeolites are even earlier.
