Catalyst New Materials Co., Ltd. is mainly engaged in the research and development, production and sales of special molecular sieves and catalytic new materials, as well as chemical technology and chemical process services.
The main products are special molecular sieves and catalysts, non-molecular sieve catalysts, catalytic application technology and chemical technical services, and the application fields include environmental protection, energy and chemical industry. The company is currently applying for listing on the Science and Technology Innovation Board.
Moreover, the issuer of the Raw Material Purchase Agreement signed between the company and BASF on April 7, 20 17 is authorized to use BASF's four patented technologies for automobile exhaust treatment for free, which is the second in the world and the only company authorized to use them in the Asia-Pacific region.
Judging from the above information, the production of the core products of China Catalyst must use BASF's authorized patents, and BASF is the only customer of the mobile source denitration molecular sieve of the corresponding core products, which makes people doubt whether China Catalyst has the ability to operate independently.
There are several kinds of numbers, and Arabic numerals are the most common one. Arabic numerals were not invented by Arabs, but by Indians. In fact, it should be listed as Hindi, but it spread to Arabia first and then to the world, so it is called "Arabic numerals".
Numbers are written symbols used to represent numbers. Different counting systems can use the same number.
About 700 years ago, the Arabs conquered Punjab, and they were surprised to find that the mathematics in the conquered area was more advanced than theirs. Later, Arabs introduced this figure to Spain. In 10 century, it was spread to other European countries by Pope Gelber Auriac.
Arabic numerals originated in ancient India, not invented by Arabs. Numbers were later mastered by Arabs for business and spread to the west.
In ancient India, urban construction needed design and planning, and sacrifices needed to calculate the movements of the sun, the moon and the stars, so mathematical calculation came into being. Around 3000 BC, the number of residents in the Indus Valley was relatively advanced, and the decimal calculation method was adopted.
