Get rid of dependence on imported raw materials! 40,000 tons/year of biological sebacic acid trial production

Recently, Shanghai Cathay Biotechnology Co.
, Ltd.
's 40,000 tons/year biological sebacic acid project production line trial production line located in Shanxi Synthetic Biology Industry Ecological Park has been recognized by domestic polymerization application customers and began to form sales, and international customers are in the process of
acceptance.
This is the first large-scale industrial production of sebacic acid by chemical production in decades!

Bioassay sebacic acid

Bio-method sebacic acid is another important milestone of Cathay Biologics after the industrialization of 11-18 carbon long-chain diacid, bio-based pentadiamine and series of bio-based polyamide, which not only further enriches the company's product layout, improves the quality of sebacic acid products, but also solves the problems
of raw material import dependence and supply stability that have always existed in the production of chemical sebacic acid in the long-chain nylon industry.

The biological method solves the problem that chemical production raw materials are heavily dependent on castor oil imports and ensures product supply
.
Theoretical utilization rate of raw materials: chemical method is only 55%, biological method can reach 100%.

Full Intellectual Property

Cathay exclusively developed the industrialization technology of bio-sebacic acid, has complete intellectual property rights, realized the large-scale production of bio-sebacic acid for the first time, and realized intellectual property protection
by combining patents and trade secrets.

Up to now, Cathay has three production bases in Jinxiang, Shandong, Wusu, Xinjiang and Taiyuan, Shanxi, and its product production capacity and supply stability have been further improved
.

The market for bio-based sebacic acid has broad prospects

Biogenic sebacic acid has significant advantages and is expected to replace chemical processes
.
Sebacic acid is a saturated aliphatic dicarboxylic acid containing ten carbon atoms, sebacic acid can synthesize aliphatic polyester, used in fibers, film-forming, casting resins, plasticizers, synthetic lubricants and adhesives and other fields
.

At present, the industry mainly uses castor oil as raw material to prepare sebacic acid by chemical method of high-temperature alkali melting and cracking, which has problems such as high energy consumption, low yield, environmental pollution, and raw material import dependence
.
The biological method can prepare sebacic acid by fermentation of yeast under room temperature and pressure, using n-decane and other alkanes as substrates, which has the performance advantages of high product purity, high yield, ash content and high temperature color performance, and can form obvious cost advantages for chemical methods with easily available raw materials and high-yield processes, and in terms of environmental protection, biological methods can also reduce carbon emissions
by 22% compared with chemical methods.

The biological process of sebacic acid has many large-scale difficulties such as difficulty in strain selection and fermentation impurities, and Cathay's breakthrough once again highlights its moat advantage in the field of biological long-chain diacids, and is expected to realize the replacement
of biological methods with chemical methods.

The global market size of sebacic acid is about 110,000 tons/year, with an output value of
about 3 billion yuan.
According to the company's announcement, the global chemical sebacic acid market size is about 110,000 tons, of which the domestic production capacity exceeds 100,000 tons / year, according to the average export unit price of sebacic acid and its salts and esters of 33,100 yuan this year, the global sebacic acid output value is about 3 billion yuan
.

Planning 900,000 tons/year bio-based polyamide project

As a global leader in bio-based long-chain diacids, Cathay Biologics focuses on the "chain" to open up and aggregate various upstream and downstream enterprises
in the industry chain.
The company has planned an annual output of 500,000 tons of bio-based pentanediamine and 900,000 tons of bio-based polyamide project; The total investment of the new project is about 13.
8 billion yuan; The new project is implemented
by Cathay (Taiyuan) Biomaterials Co.
, Ltd.
, a holding subsidiary of the company.

In addition, Cathay (Wusu) has an annual output of 50,000 tons of bio-based pentylenediamine and an annual output of 100,000 tons of bio-based polyamide production line has been put into operation as scheduled at the end of the first half of 2021, which is the world's first bio-based pentylene diamine industrialization and the world's first 10,000-ton bio-based polyamide production line
