Title: Method for conducting thermonuclear reaction in magnetic fusion reactor
Inventor: NASTOJASHCHIJ A F
IPC: G21B1/00
Filed: 2001-08-22
Granted: 2003-09-10
Abstract: FIELD: controlled fusion; extracting fusion energy, generating three-dimensional neutron sources (for instance to recover nuclear wastes). SUBSTANCE: method involves irradiation of heavy particles of fuel pellets injected in reactor chamber wherein high pressure of working gas not lower than atmospheric pressure is maintained using laser pulses or beams for the purpose. In the process problems of production of hot plasma, maintenance of inertialess current, and monitoring of plasma-magnetic configuration are solved. Circuit arrangement of magnetic fusion reactor of proposed type enables directly placing the installation in steady state running dispensing with rather sophisticated standard scheme of organizing hot plasma (gas breakdown at low working gas pressure, preheating of plasma with ohmic current, and the like). Proposed reactor enables combining advantages of magnetic heat insulation and near-wall plasma confinement implemented by building up so-called high- pressure gas cushion at plasma boundary. Proposed method may be found useful for installations with magnetic field configuration of tokamak, stellarator, or adiabatic trap type. Near-wall plasma confinement used in tokamaks makes it possible to avoid dangerous instability of discharge failure. As rather high pressure (and density) of plasma can be maintained in proposed reactor (compared with traditional magnetic confinement of plasma), this reactor can be used for conducting fusion reactions at low section of reactions (for instance in case of D+He 3  nuclei fusion reaction). EFFECT: enlarged functional capabilities. 1 cl, 1 dwg

Abstract: FIELD: rubber industry. 
     SUBSTANCE: butyl rubber is produced via isobutylene/isoprene copolymerization in diluent and/or solvent medium. Isobutylene is obtained through hydration of isobutylene contained in starting isobutylene-containing fractions obtained by pyrolysis of hydrocarbon feedstock, catalytic cracking, isobutane dehydrogenation, isomerization of linear butanes via intermediate trimethylcarbinol, which is dehydrated into isobutylene followed by isolation of trimethylcarbinol dehydration products by compression and rectification. Thus obtained isobutylene is used for blending with isoprene and return diluent and/or solvent containing unreacted isobutylene. Blend is then copolymerized with isoprene in presence of catalyst. Process also includes deactivation of catalyst, degassing of rubber, processing of return products distilled off in the course of degassing by condensation, compression, and rectification, recovery and drying of rubber. Process is characterized by that isobutylene from water-washed trimethylcarbinol dehydration products is subjected to two-step rectification: first under mild conditions of temperature 45-50 о С in bottom section of the first column and reflux-to-product ratio 3.0-4.0 and then, after mixing first-step still residue with condensate isobutylene-containing blowings obtained during isobutylene-into-trimethylcarbinol hydration process, under sever condition of temperature 90-135 о С in bottom section of the second column and reflux-to-product ratio 0.7-1.2. Isobutylene distilled of in the first rectification stage is conveyed, after azeotropic drying, to isobutylene/isoprene copolymerization zone and isobutylene distilled of in the second rectification stage is conveyed, as starting isobutylene-containing fraction, to isobutylene-into-trimethylcarbinol hydration process and/or to synthesis of 4,4-dimethyl-1,3-dioxan, optionally in combination with methyl tert-butyl ether.
