  • Patent number: 9266804
    Abstract: A dual-bed catalytic distillation tower has a catalytic column having an upper catalytic bed filled with low temperature dehydration catalysts and a lower catalytic bed filled with high temperature dehydration catalysts. When using the dual-bed catalytic distillation tower, the feeding may be fed to the tower at the top of the upper catalytic bed, between the upper and lower catalytic beds, or at the bottom of the lower catalytic bed for dehydration to obtain DME. The dual-bed catalytic distillation tower has the advantage of flexible set-up depending on various feedings such as anhydrous or crude methanol and on different grades of DME to be obtained.

  • Patent number: 9181159
    Abstract: This invention describes a method for co-producing isobutene and methyl tert-butyl ether in a catalytic distillation column, wherein contacting with solid acid catalysts the charged tert-butanol mixture undergoes dehydration and etherification. The mixture of isobutene and methyl tert-butyl ether withdrawn from the column top can be further separated, thus high purity isobutene and fuel-additive methyl tert-butyl ether are obtained.

  • Patent number: 9169183
    Abstract: This invention describes a method for co-producing isobutene and ethyl tert-butyl ether from tert-butanol mixture in a catalytic distillation column, wherein catalyzing the tert-butanol mixture with the ethanol undergoes dehydration and etherification. The tert-butanol mixture contains absolute ethanol or aqueous ethanol as the antifreeze agent. The isobutene and the ethyl tert-butyl ether withdrawn from the column top are further separated, thus high purity isobutene and ethyl tert-butyl ether for fuel-additive are obtained.

  • Publication number: 20150175502
    Abstract: A method for making high purity dicyclopentadiene comprises the following steps: providing a dimer feedstock comprising dicyclopentadiene and methyl dicyclopentadiene; blending the dimer feedstock and a diluent to obtain a first blend; cracking the first blend in a vapor phase at 300° C. to 400° C. to obtain a cracked feedstock; separating the cracked feedstock into a second blend and a third blend; dimerizing the second blend at 50° C. to 120° C. to obtain a fourth blend; and separating the fourth blend to obtain a recycled diluent and high purity dicyclopentadiene. By using saturated C5 hydrocarbon, saturated C6 hydrocarbon, benzene and the mixture thereof as the diluent and the steps mentioned above, the clogging problem of cracker tubes is solved and the cost of makeup diluent usage is lowered.
