Abstract

This patent describes a process for manufacturing char and hydrocarbons from discarded used tires. The process consists of: introducing the substantially whole tires into a reactor; pyrolyzing the substantially whole tires in a reaction chamber continuously at a temperature and pressure and for a reaction time sufficient to cause the tires to dissociate into a vapor and a solid phase; the pyrolyzing step including directly heating the tires with a radiant heat source at temperatures of 1000{sup 0} to 3000{sup 0}F; producing char from the solid phase; and processing the vapor phase to produce hydrocarbons.

Recovery process

Patent Apffel, F

A process is described for manufacturing carbon black and hydrocarbons from discarded tires, comprising: introducing the tires into a reactor; pyrolyzing the tires in a pyrolysis reaction vessel substantially in the absence of artificially introduced oil heating media at a temperature and pressure and for a reaction time sufficient to cause the tires to dissociate into a vapor phase and a solid phase; the pyrolyzing step including directly, internally heating the tires in the reaction vessel using microwave energy; producing carbon black from the solid phase; and processing the vapor phase to produce hyrocarbons.
Power generation and potable water recovery from salinous water

Patent Carson, D

A process is disclosed for simultaneously generating power and recovering potable water from a source of salinous water--e.g., seawater. Salinous water, from a locus which is proximate to the surface of the source and at a relatively high temperature--e.g., about 85/sup 0/F--is exposed to radiant solar energy to increase significantly the temperature thereof--e.g., to a level of at least about 135/sup 0/F. The heated water is introduced into a plurality of flash separation zones, each succeeding one of which is maintained at a lower subatmospheric pressure than the preceding zone, to provide substantially non-salinous vapor phases. The salinous liquid phasemore »« less

Method of synthesizing and growing copper-indium-diselenide (CuInSe/sub 2/) crystals

Patent Ciszek, T

This patent describes the process of preparing a CuInSe/sub 2/ crystal substantially free of fissures, cracks and contamination from B/sub 2/O/sub 3/ and SiO/sub 2/, the process comprising the steps of: placing stoichiometric quantities of Cu, In, and Se in a refractory quartz crucible; placing a sufficient quantity of B/sub 2/O/sub 3/ in the crucible over the Cu, In, and Se to completely surround the Cu, In, and Se when melted to a liquid and to substantially prevent a reaction between the CuInSe/sub 2/ crystal and the quartz crucible; placing the crucible containing the Cu, In, Se, and B/sub 2/O/submore »« less
