The first industrial plant for the hydrogenation purification of crude benzene using domestically produced catalysts was successfully commissioned. Volume 40, Issue 4, 2009, \"Zhejiang Chemical Industry\" – The hydrogenation purification catalyst developed by Group 602 of the Shandong Coal Chemistry Research Institute was used in the 8-ton/year hydrogenation purification plant operated by Shandong Tengzhou Shengyuan Chemical Co., Ltd.; production of qualified products began on March 29th. This is our country’s first set of industrial production facilities for domestic hydrogenation refining catalysts; previously, all domestic facilities used imported catalysts. Crude benzene is a by-product of the coking process; currently, China’s production of crude benzene amounts to nearly 3 million tons per year. The hydrorefining technology for crude benzene is an advanced green and environmentally friendly process, as it gradually replaces the acid washing method, which is energy-intensive and causes severe environmental pollution. The main products of this process are benzene, toluene, and xylene, all of which meet the standard requirements for Jian Petroleum products and can satisfy the needs of the production of high-end downstream products. The pre-hydrogenation catalyst and main hydrogenation catalyst for the hydrorefining of crude benzene, developed by Group 602 of the Shanxi Coal Chemistry Institute of the Chinese Academy of Sciences, feature high activity, good selectivity, and a long service life, and can fully replace similar catalysts from other sources. Previously, the processes and equipment for crude benzene hydrogenation had already been localized in China; the successful application of this catalyst signifies that the entire set of technologies for the hydrogenation purification of crude benzene is now available domestically.
Warm congratulations on the successful commissioning of the first industrial plant for the hydrogenation refining of crude benzene using domestically produced catalysts.
The successful first operation of domestic benzene hydrogenation technology is no easy feat; many domestic companies wanted to cooperate with foreign parties in this area of production. Now that we are able to do it on our own, it is a source of pride for the Chinese people and a source of honor for the chemical industry.
Positive outlook! I hope the company can also undertake a benzene hydrogenation project! Make the chemical industry stronger!
Will BASF’s attitude toward customers be better in the future?
I hope that domestic catalysts will enhance our country’s prestige and ultimately drive foreign brands out of the Chinese market!
There have been domestic versions for a long time; there’s nothing to boast about.
Well, they’ve been around for a while already… Domestic catalysts; they look good, but I’m not sure about their longevity and stability. It is understood that there is still a gap between domestically produced products and imported ones at present.
The Shanxi Coal Chemical Research Institute has in-depth research in benzene hydrogenation and benzene desulfurization.
The trend is toward domestic production of catalysts; it’s just not clear what their service life will be like or what their performance will be
Domestic catalysts have existed for a long time; it’s a shame they haven’t been used in benzene hydrogenation units! This is the first one! 7# sjdy
