摘要： Solid carbonaceous fuel is dried to a desired moisture content, cooled, and stored in an atmosphere having a controlled humidity and oxygen content to prevent heat generation which causes spontaneous combustion. A suitable atmosphere is produced by displacing air in a storage enclosure with dehumidified combustion gases.

摘要： A new process for preparing haloalkyl epoxides and oxaziranes is described in which a mixture of an perhalo alkene or alkyl imine and chlorine gas is contacted with a Group IA, IIA metal oxide, carbonate or bicarbonate under mild conditions of temperature and pressure. The process, using perhalo alkenes or perhalo alkyl imines as starting material, represents a new economical, facil preparation of the monomer hexafluoropropylene oxide, such monomer is capable of polymerizaton or copolymerization to thermally stable and inert polymers.

摘要： A process for treating a molecular sieve-containing alkylation catalyst to increase its selectivity for monoalkylation in which the alkylation catalyst is contacted with a feedstock comprising at least one organic compound under conditions such that a sufficient amount of carbonaceous material evenly deposits on the alkylation catalyst to substantially suppress its alkylation activity. The carbon-containing catalyst particles are then subjected to combustion by contacting them with a gaseous oxidizing agent at an elevated temperature to remove at least a portion of the carbonaceous material, preferably substantially all of the carbonaceous material, thereby increasing the selectivity of the catalyst for monoalkylation by at least about 1.0 percentage point. The resulting alkylation catalyst an be used to alkylate benzene and other aromatic compounds with ethylene, propylene or other olefins to produce high yields of ethylbenzene, cumene and other alkylated products. Preferably, the alkylation catalyst contains an ammonium-exchanged and steam stabilized Y zeolite.
