    摘要: The present invention is related to a method for kinetically separating a light hydrocarbon mixture comprising at least two components by preferentially adsorbing a first component on a zeolite adsorbent comprising 8-member rings of tetrahedra as the pore opening controlling hydrocarbon diffusion and alkali metal cations balancing a framework charge, wherein a second component is not preferentially adsorbed. The novel process comprises contacting the light hydrocarbon mixture with a zeolite adsorbent having a SiO2/Al2O3 ratio greater than about 50 and less than 200 and further having a diffusion rate at least 50 times greater for the first component as compared to the second component, and then recovering at least one of the first component or the second component.

    摘要: The present disclosure generally relates to cache memory systems and/or techniques to identify dead cache blocks in cache memory systems. Example systems may include a cache memory that is accessible by a cache client. The cache memory may include a plurality of storage locations for a first cache block, with a most recently used position location in the cache memory. A cache controller may be configured to predict whether the first cache block stored in the cache memory is identified as a dead cache block based on a cache burst of the first cache block. The cache burst may comprise a first access of the first cache block by a cache client and any subsequent contiguous accesses of the first cache block following the first access by the cache client while the first cache block is in a most recently used position of the cache set.

    摘要: Acesulfame-K is a widely used sweetener in food and beverage. It is prepared by using the substituted sodium phenoxide or substituted phenol as the starting substance to synthesize the following three intermediates: a substituted phenoxide sulfonylchloride(I), a substituted phenoxide sulfonylamide(II) and an acetoacetamide-N-sulfonyl-substituted phenoxide(III). Particularly, II was prepared by using the liquid or gaseous ammonia to react with I under the action of some catalysts in a reaction column. III was prepared by using II to react with diketene. Acesulfame-K was prepared by ring-closure in III with methanol solution of KOH or K2CO3.
