The performance of a novel circulating fast fluidized bed membrane reformer (CFFBMR) is investigated using a reliable mathematical model. The removal of product hydrogen using hydrogenpermselective membranes ‘‘breaks’’ the thermodynamic equilibrium in the reversible system and makes it possible to operate the process at lower temperatures. The oxidative(More)
The study was undertaken to assess the contents of heavy metals (Cu, Zn, Cr, Pb, Cd, As and Hg) in sea cucumber (Apostichopus japonicus) juveniles from coastal areas of Bohai and Yellow seas in northern China. Sea cucumber juveniles were collected from twenty commercial hatcheries distributed in five coastal cities. The mean concentrations obtained for(More)
Concentrations of Cu, Zn, Cr, As, Cd, Pb and Hg were determined in 153 samples covering 18 fish species collected from Heilongjiang River, China, and the potential health risks to local residents through fish consumption were estimated. Results revealed that all metals were detected with Cd and Pb having considerably lower detection rate. There were 28.6 %(More)
