Schroeder Process

Three other processes that electrolytically convert HC1 to Cf using metal chloride catalyst are the Schroeder process, using NiCf the Westvaco process, using CuC and the South African process, using MnC. None of these processes is commercial. The Schroeder process illustrates the principles involved in these technologies. The Schroeder process is cyclic and involves two steps. The metal chloride is electrolyzed to produce the metal and chlorine ... 

In the Schroeder process (Figure 19.19), pulverized, dry coal is hydrogenated at pressures and temperatures of approximately 500°C (930°F) and 2000 psi (13.8) in an entrained system in which the residence time of the feed coal is less than 1 min. The products are separated into light liquids (approximately 30%), heavy liquids (approximately 5%), char (5%), and gases (30%). The heavy liquids can be hydrotreated to produce further quantities of usable (light) liquids. The reaction may be accelerated by the use of ammonium molybdate (1% w/w) that has been impregnated on to the coal.

The flowsheet in Figure 6 is somewhat analogous to that proposed and tested by Mclsaac, Baker, Krupa, LaPointe, Meikrantz, and Schroeder C3) for processing HLLW from LWR using DHDECMP. The major differences are the larger phase ratios in the extraction...

There are many potential applications of filaments (some of which have been discussed above) that require exercising control over the multiple fila-mentation process. We discuss some of the methods that might possibly be of utility in this respect. To control filamentation in air, [43] introduced amplitude masks at the input of the incident beam. Schroeder et al. [55] performed...

The first artificial reverberators based on discrete-time signal processing were constructed by Schroeder in the early 1960 s [Schroeder, 1962], and most of the important ideas about reverberation algorithms can be traced to his original papers. Schroeder s original proposal was based on comb and allpass filters. The comb filter is shown in figure 3.12 and consists of a delay whose output is recirculated to the input. The z transform of the comb filter is given by ...

Occupational exposure to barium primarily occurs in workers and miners who inhale barium sulfate (or the ore, barite) and barium carbonate dust during the mining of barite and the manufacturing and processing (e.g., mixing, grinding, and loading) of barium compounds (Beliles 1979 Reznik and Toy 1978 Schroeder 1970).
