China's first large-scale export of hydrogenation catalysts

Recently, at the bidding meeting for residue hydrotreating catalysts organized by the Indonesian National Petroleum Corporation, the China Petrochemical Tendering Group won the bid and won orders for nearly 500 tons of residue hydrogenation catalyst, achieving the first large-scale hydrogenation technology and catalyst in China. Exports indicate that China's residual oil hydrogenation technology and catalyst have reached the international advanced level.
Residue hydrotreating catalysts and process technologies are complete sets of technologies developed by Sinopec Research Institute after 20 years of development with independent intellectual property rights. This technology won the first prize of National Science and Technology Progress Award in 2002 and successively applied in Qilu Petrochemical, Dalian West Pacific, Maoming Petrochemical, and Hainan Refining and Chemical Industry, providing strong technical support for rational utilization and deep processing of inferior or heavy crude oil. Maoming Petrochemical The 2 million-ton/year resid hydrotreating unit is designed and constructed based on this technology, which breaks the monopoly of resid hydropower technology by foreign large companies. At present, more than 130 patents have been filed around this technology and have become the fist technology of Futusian Academy.
While serving domestic enterprises, the Fudan Institute joined hands with catalyst producers to actively expand the international market. Since 2002, they have conducted technical discussions with Indonesian National Petroleum Corporation on residue hydrogenation technology and have conducted two more than 10,000 hours of catalyst life tests. Together with the test results and successful experience gained in domestic industrial installations, they put forward a complete technical solution that has been approved by the Indonesian side, established as a qualified supplier, and invited to participate in the residue hydrogenation catalyst organized by the Indonesian National Petroleum Corporation. .
At the tender meeting, the Sinopec bidding team, which consists of the Fushun Research Institute, the Catalyst Branch, and Sinopec International Division, competed with the large foreign companies such as Chevron and Albemarle. After many rounds of hard negotiations and unremitting efforts, Sinopec won the bid with rigorous bidding plans, reasonable prices, and rigorous and pragmatic style, fully demonstrating that China's residual oil hydrogenation technology and catalysts are at the same level as international petrochemical companies. Competing strength.

Weld Materials

1.Welding materials

In Welding, substances called filler materials or consumables are used. As the name implies, these substances provide filler or a body of molten materials that provides a strong bond to be formed between the base metals used. Most welding processes will also require some form of shielding to protect both the main components and filler from being oxidized during the process.


The type of welding materials used during welding depends on the nature of the job intended. Electrodes draw the necessary energy in order to perform welding applications. Luoyang Golden Egret Company has any kind of welding materials include CTC Welding Rod /rope, SCTC welding rod/rope, TC electronic welding rod, Ni-based welding rod, flux-cored Welding Wires, solid welding wires and etc.

Welding can be applied in different kinds of industries such as building and construction, oil and gas, marine, power generation, steel, mine tools, automobile, transportation and etc.
