摘要： An integrated process for utilizing waste heat from a glass making furnace. The hot off-gas from the furnace is initially partially cooled, then fed to a reformer. In the reformer, the partially cooled off-gas is further cooled against a hydrocarbon which is thus reformed into a synthesis gas, which is then fed into the glass making furnace as a fuel. The further cooled off-gas is then recycled back to absorb the heat from the hot off-gas to perform the initial cooling.

摘要： A process for preparing an alkyl-tert-alkyl ether wherein an olefin having a double bond on a tertiary carbon atom and a primary alcohol are reacted in the presence of a catalyst under conditions sufficient to produce an azeotropic alcohol/ether/hydrocarbon mixture containing the alkyl-tert-alkyl ether. The azeotropic alcohol/ether/hydrocarbon mixture is subjected to a cyclic liquid phase adsorption process sequence to selectively remove the alcohol. The resulting non-azeotropic ether/hydrocarbon stream can then be easily separated by distillation to provide the desired alkyl-tert-alkyl ether product and a hydrocarbon product. The cyclic adsorption process employed to separate the alcohol from the ether/hydrocarbon mixture comprises introducing the alcohol/ether/hydrocarbon mixture into a plurality of adsorption colums containing an alcohol selective adsorbent, wherein each respective absorption column undergoes successive steps of adsorption and desorption.
