BDO core catalyst realizes localization

Sinochem News.
com reported last week from Henan Kaixiang Fine Chemical Co.
, Ltd.
that the first domestic production line of 1,4-butanediol (BDO) using domestic catalysts was installed in the company’s 2×45,000 tons/year1, Successful operation on the 4-butanediol device
.

The chosen core means --1,4- butynediol catalyst synthesis catalyst RK-17 (oxide) is provided by Dalian Rick Technology Corporation
.
The successful application of this catalyst makes Dalian Ruike the first manufacturer in China to realize the industrial production and application of this type of catalyst

At present, the catalyst has been successfully operated for more than one year in Henan Kaixiang Fine Chemical
.
The operating data shows that the performance of the Dalian Ruiker 1,4-butynediol synthesis catalyst RK-17 is relatively stable during the trial period compared with the imported catalyst

The 1,4-butanediol industry is in an upward cycle
.
Using acetylene and formaldehyde as raw materials, the production of 1,4-butanediol by the modified acetylene aldehyde method is still the mainstream process route, that is, acetylene and formaldehyde react to synthesize 1,4-butynediol under the action of a catalyst, and then add Hydrogen produces 1,4-butanediol

In 2017, Dalian Ruike developed 1,4-butynediol synthesis catalyst RK-17 (oxide type) with good activity, good stability, high selectivity and good filterability
.
The catalyst is mainly composed of oxides of copper, bismuth, magnesium, silicon, etc.

In January 2020, the first batch of 15 tons of catalysts was tested in Henan Kaixiang Fine Chemical Co.
, Ltd.
's 2×45,000 tons/year 1,4-butanediol column C reactor, and its performance indicators reached or exceeded foreign catalysts
.

In July 2020, the reactors of Column A and Column B of Kaixiang Chemical also used Dalian Ruiker's 1,4-butynediol synthesis catalyst RK-17
.
The catalyst promotes and increases the reaction rate of the formaldehyde solution and acetylene gas in the acetylation reactor of the 1,4-butanediol device, and increases the reaction conversion rate under the same reaction time, and finally increases the 1,4-butanediol product Production efficiency and quality
