Compatltlva affects In the adsorption of CH,I on KC 96106660 impregnated actlvatad carbon8 In the presence of CO, Malik, A. A. et al., Carbon, 1996, 34, (4), 439-447. Nuclear installations use activated carbon in purpose-designed adsorption plants to control the release of radioactive iodine and iodine-containing compounds in the gaseous discharges. The control of gaseous radioactive discharges is a regulatory requirement, and the effective performance of the iodine trapping plant is assumed in plant safety cases. The paper describes an investigation of the adsorption of CH,I on a KI-impregnated carbon and the influence of competitive adsorption on the process. A comprehensive assessment of the potential to 96106561 reduce methane amlaalona from U.S. coal mlnaa
Schult, K. Intergas 95, Proc. Inl. Vnconv. Gas Symp., Univ. ofAlabama, Tuscaloosa, Ala., USA, 1995, 477-482. The USEPA Coalbed Methane Outreach Program identified the best prospects to reduce CH, emissions from U.S. coal mines. The findings of 3

Computer-aided simulation of efficiency of an alecSe/O6562 troatatic precipitator Khare, M. and Sinha, M. Environment Int., 1996, 22, (4), 451-462. A computer simulation algorithm has been developed to simulate the efficiency of an electrostatic precipitator, operated in positive corona mode. The electric field at various predefiied grid points between the plates and electrodes, as well as the drift of charged fly ash particles have been obtained under steady-state conditions, using known input data.

Continuous-flow biological studies of a synthetic eastern oil shale processing liquid waste Lowhorn, R. W. et pl:, Adv. Filtr. Sep. TechnoL, 1995, 9, 705-719. The pressurized fluldlzed-bed hydroretorting (PFH) of eastern US oil shales are an efficient process of removing hydrocarbons from this deficient oil shale. The process produces a liquid waste byproduct that contains numerous organica. Some of these organics have already been identified by the US EPA as potentially hazardous to human health and the environment.

Nijpels, former Minister of the Environment, whose present functions include presidency of the Dutch branch of the World Wildlife Fund and chairmanship of the Gaskeur Foundation, is a bit disappointed about the Energy Memorandum of Minister of Economic Affairs, Wijers. ‘I think the vision is alright, but it’s a pity he doesn’t turn it more into a policy. The envisaged result of the Enernv Memorandum is half of what could be attained.

The release of nitrogen oxides during the combustion of coal chars is a maior environmental oroblem. In this studv. the effect of iron catalvsts on the-release of NO during the combustion o1.a suite of carbons was i&estigated using a thermogravimetric analyser-mass spectrometer. The anisotropic carbons were prepared from acenaphthylene while the isotropic caibons were prepared from polyvinylidene-chloride and a phenolic resin. Nitrogen was incorporated in the carbon structure by treatment with ammonia. A range of catalyst impregnation and sample treatment procedures were used and the temperature programmed combustion characteristics of the resulting carbon samples were studied.
