The invention relates to a process for producing alkylated aromatics, preferably ethylbenzene, in a multiple bed reactor in which at least two catalysts, each comprising a molecular sieve, are used in sequential beds. Each access terminal has respective multimedia capabilities, and the domain includes an application server for accessing the multimedia services. The executive drivers, instead of platform drivers, are executed by UEFI dispatchers. After a series of processes, such as scattering, reflection, phase retardation and polarization beam-splitting, the light beam will pass through the polarization splitting film being of a single polarization state such that it could be utilized by electro-optical systems, such as liquid crystal displays.
