China University of Petroleum (East China) announced on June 22 that a new type of propane/butane dehydrogenation (ADHO) technology developed by the State Key Laboratory of Heavy Oil at the school and designed by the East China Design Branch of China Petroleum Engineering and Construction Company.
The industrialization test in Shandong Hengyuan Petrochemical Co.
, Ltd.
was successful
.
This alkane dehydrogenation technology, which has been studied with great concentration for seven years, has filled the domestic gap
.
At present, China's propane and isobutane dehydrogenation technologies are all imported from abroad.
In industry, the catalysts used in propane and isobutane dehydrogenation devices are generally supported precious metal platinum or toxic chromium catalysts.
Platinum catalysts are expensive and raw materials Deep purification is required, and the use of chromium-based catalysts has serious environmental problems
.
The development of environmentally friendly non-precious metal catalysts has always been a technical problem for propane/butane dehydrogenation
.
In order to solve this problem, the research group of Professor Li Chunyi of the State Key Laboratory of Heavy Oil, China University of Petroleum (East China), after seven years of painstaking research, successfully developed a non-toxic and non-corrosive non-noble metal oxide catalyst, and developed supporting facilities for it.
The high-efficiency circulating fluidized bed reactor successfully realized the dehydrogenation reaction and the continuous catalyst coking regeneration
.
The industrialization test results of Shandong Hengyuan Petrochemical Co.
, Ltd.
showed that the single-pass conversion rate of alkanes, the yield and selectivity of olefins are equivalent to the more imported Russian Snamprogetti technology in China, filling the gap in this technical field in China
.
The new propane/butane dehydrogenation (ADHO) technology has the following characteristics: raw materials can be directly reacted into the device without pretreatment, eliminating the need for complex technical processes such as desulfurization, arsenic removal, and lead removal; it is suitable for propane, Isobutane dehydrogenation alone is also suitable for the mixed dehydrogenation of propane and butane; the reaction and catalyst regeneration are carried out continuously, and the production efficiency is high; the catalyst is non-toxic and does not pollute the environment; the catalyst is a refractory oxide, which is non-corrosive and beneficial The device operates safely and stably for a long period of time; the catalyst has high mechanical strength and low agent consumption
.
It is reported that China has relatively abundant liquefied petroleum gas.
The liquefied petroleum gas is mainly composed of propane, n-butane and isobutane.
The dehydrogenation of alkanes to olefins can not only increase the high added value of products, and reduce the impact of olefin production on the cracking process.
Dependence, and can also by-produce hydrogen with higher added value, and improve the level of comprehensive utilization of oil and gas resources
