Abstract: The invention discloses a method for purifying butylene oxide by using an anion exchange resin and an adsorbent. The anion exchange resin removes acid and aldehyde impurities while the adsorbent removes water impurities from the butylene oxide. Depending upon the impurity level, the purification steps can be conducted singularly or in combination, and the process can proceed either batchwise in a reactor or continuously in a column. The ion exchange resin of the choice is a sulfonated macroreticular anion exchange resin and the adsorbent of choice is a molecular sieve.

Abstract: The shed or hall for a set of coke ovens defining a door region for supporting a coke transfer carriage, a quenching region for supporting a quenching carriage, and a washer region, comprises a central upright partition disposed between the quenching and washer regions and having its top portion bent about 180.degree. to form a guiding surface communicating with the washer region, a roof supported above the respective regions and accommodating an upper guiding metal sheet and an intermediate metal sheet forming together with the guiding top portion of the upright partition two (2) fume discharging channels communicating respectively with the door region and the quenching region and at the other end, with the washer region.
