Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a system and a process for the recovery of at least one halogenated hydrocarbon from a gas stream.

SOLUTION: The recovery includes adsorption by exposing the gas stream to an adsorbent with a lattice structure having pore diameters with an average pore opening of between about 5 and about 50 Å. The adsorbent is then regenerated by exposing the adsorbent to a purge gas under conditions which efficiently desorb the at least one adsorbed halogenated hydrocarbon from the adsorbent. The at least one halogenated hydrocarbon (and impurities or reaction products) can be condensed from the purge gas and subjected to fractional distillation to provide a recovered halogenated hydrocarbon. An adsorbent for adsorbing a halogenated hydrocarbon comprises: a first adsorbent comprising a silica that has an organophilic pore lattice structure with an average pore opening of between 5 and 10 Å; and a second adsorbent comprising an amorphous silica that has an organophilic pore lattice structure with an average pore opening of between 15 and 30 Å, in which the first adsorbent is separated from the second adsorbent and the adsorbent for adsorbing a halogenated hydrocarbon has Al2O3 content of less than 10 mass%.

【課題】ガス流から少なくとも1つのハロゲン化炭化水素を回収するシステムとプロセスの提供。
【解決手段】平均細孔開口径が約5〜約50Åの格子構造を有する吸着剤へのガス流の暴露による吸着を含み、その後、前記少なくとも1つの吸着されたハロゲン化炭化水素を前記吸着剤から効率的に脱離する条件下で、前記吸着剤をパージガスに暴露して吸着剤を再生する。前記少なくとも1つのハロゲン化炭化水素(および不純物または反応生成物)を前記パージガスから凝縮し分留し、回収・精製されたハロゲン化炭化水素。平均細孔開口が5〜10Åの有機親和性細孔格子構造を有するシリカを含む第1の吸着剤と、平均細孔開口が15〜30Åの有機親和性細孔格子構造を有する非晶質シリカを含む第2の吸着剤と、を含み、前記第1の吸着剤は、前記第2の吸着剤から分離されており、Al含量が10質量%未満であるハロゲン化炭化水素吸着用吸着剤。
