background and purpose: the performance of full-scale moving bed biofilm reactor (mbbr) was evaluated as an alternative for upgrading of kish island mirmohana wastewater treatment plant. in this study activated sludge process upgrade to mbbr process and different operating parameters were compared. materials and methods: effect of upgrading on different parameters such as organic loading rate (...

Metal hydride applications span a wide variety of tech! nologies\ e[g[\ energy conversion\ chemical compressors and hydrogen storage[ A knowledge of heat and mass transfer in a metal hydride reactor during the absorption and desorption of hydrogen is important for performance optimization of the reactor[ One of the key requirements in the design of metal hydride bed is the enhancement of the e}...

Recent experiments have shown that silane pyrolysis in a gas-solids fluidized bed may be an attractive way to produce ultra-pure silicon. Such a process would possess the general advantages of fluidized bed technology, namely, good contacting, thermal homogeneity, thorough mixing of particles, easy solids handling, and low pressure drop. Such a fluidized bed reactor is simulated using the two-f...

Executive Summary The Clean Coal Technology (CCT) Program is a government and industry co-funded effort to demonstrate a new generation of innovative coal-utilization processes in a series of " showcase " facilities built across the country. These projects are carried out on a sufficiently large scale to prove commercial worthiness and generate data for design, construction, operation, and tech...

in this study the catalytic dehydrogenation of ethylbenzene to styrene was investigated in a simulated tubular sodalite membrane reactor. the high quality microporous sodalite membrane was synthesized by direct hydrothermal method and characterized by single gas permeation measurements. the performance of the prepared membrane showed high potential for application in a dehydrogenation membrane ...

Some characteristics of Upflow Anaerobic Sludge Blanket (UASB), Expended Granule Sludge Blanket (EGSB), and Static Granular Bed Reactor (SGBR) were investigated in order to compare performances of the three and recognize advantages and disadvantages, respectively. The UASB reactor is developed in the late 1970s and became rapidly widespread due to great performances. With granules, this reactor...
