Abstract: An electrical power storage unit has one or more metal-gas electrical cells, each cell including a pair of generally planar outer electrode units configured to define therebetween an interior space for containing an electrical power storage medium and an inner electrode unit mounted between the pair of outer electrode units so as to be in electrically conductive contact with the electrical power storage medium and define a plurality of volumes each having a pair of open ends, each open end facing an adjacent outer electrode unit. The power storage medium is a slurry containing active metal particles and an electrolyte solution. The inner electrode unit is configured for removable insertion within the interior space. The volumes defined by the inner electrode unit are configured so as to contain portions of the power storage slurry such that removal of the inner electrode unit from the interior space causes the simultaneous removal therefrom of the major part of the power storage slurry.

Abstract: There is disclosed an improved process for the production of linear alkylbenzene wherein monoolefins are reacted with benzene in a hydrogen fluoride catalyzed reaction followed by recovery of the alkylbenzene. An alumina treatment step is included which removes organic fluoride impurities in order to prevent release of hydrofluoric acid in downstream equipment. It has been discovered that the SO.sub.3 sulfonation color of the alkylbenzene is surprisingly improved by the use of a high selectivity basic alumina for this treatment.
