Technology for isomerizing n-butylene to isobutylene

Currently, carbon tetra resources after etherification are in short supply in the domestic market. Launching isomerization projects does not yield good returns, unless the process is extended downstream via isobutylene

The overall energy consumption for conversion is too high, resulting in poor efficiency

Reply to 3# yilu: Are there any specific figures? Material balance, utility consumption

Several sets have already been installed in China; the raw materials are of good quality and the returns are satisfactory.

The technology is no problem; several sets have been built, and the performance is satisfactory. The current processing of C4 olefin liquefied gas involves aromatization, isomerization, cracking to produce propylene, and alkylation. Further processing steps include propane dehydrogenation, isobutane dehydrogenation, and even n-butane isomerization. C4 olefin reprocessing technology: Aromatization is already well-developed, but due to the fact that the price of liquefied gas after aromatization is 400–500 yuan per ton lower than that of the raw material liquefied gas, the economic viability of aromatization becomes very poor ； Isomerization technology converts butylene into isobutylene for further processing, offering decent overall benefits ； The production of propylene via C4 olefin cracking also offers good benefits ； Alkylation is currently mainly based on the introduction of technology ； Propane dehydrogenation is relatively well-developed in China within the C4 hydrocarbon processing technology; extending the industrial chain further also yields good benefits ； Isobutane dehydrogenation technology still relies on technology imports at present ； There is currently no technology for butane isomerization.

Approximately 33 tons of steam are used per shift, and about 18,000 kWh of electricity is consumed per shift

Could the poster leave a contact method? We are a manufacturer of catalysts for the isomerization of n-butylene to isobutylene. Would it be possible to discuss this further? My phone number is 13795382798; I’m Liu.

Currently, there is a system in China for producing isobutylene from isobutane dehydrogenation; it’s just not clear whether its efficiency is good or not

Does anyone know which company in Shandong is going to put into operation a butylene isomerization unit with a capacity of 150,000 tons this second half of the year?

Does the statement that \"about 33 tons of steam are used per shift, and about 18,000 kWh of electricity is consumed per shift\" refer to the isobutylene isomerization unit? What is the scale of this heterogenization?
