Heat is stored by melting a mixture of salts contained in compartments between an inner and an outer tube and radial copper fins which taper in radial outward direction. The molten salts solidify upon passage of relatively cold water through the inner tube, but formation of salt deposits on the fins is deferred so that liquid salt interfaces directly with the fins for an extended period of time during heat extraction.

A method of producing high yields of olefins from hydrocarbon feedstocks which is particularly applicable to heavy hydrocarbons. In accordance with the present method, a stream of gaseous oxygen is introduced into a first reaction zone and a cocurrent flow of hydrogen is introduced about the periphery of the gaseous oxygen stream, the hydrogen being introduced at a temperature at which it will spontaneously react with the oxygen. The hydrogen and oxygen are introduced in amounts to provide a gas stream of reaction products having an average temperature within the range of from about 1,000. degree. to 2,000. degree. C. and which comprises a major amount of hydrogen and a minor amount of water vapor. The gas stream so produced is introduced into a second reaction zone and impinged upon a stream of hydrocarbon which is heated to a temperature in excess of its melting point but below the temperature at which any substantial coke or tar forms. The gas stream is introduced at a high velocity and in an amount to provide a flowing reaction mixture having a temperature within the range of from 800. degree. to 1,800. degree. C.

An improved process for producing a methane-enriched gas wherein a hydrogen-deficient carbonaceous material is treated with a hydrogen-containing pyrolysis gas at an elevated temperature and pressure to produce a product gas mixture including methane, carbon monoxide and hydrogen. The improvement comprises passing the product gas mixture sequentially through a water-gas shift reaction zone and a gas separation zone to provide separate gas streams of methane and of a recycle gas comprising hydrogen, carbon monoxide and methane for recycle to the process. A controlled amount of steam also is provided which when combined with the recycle gas provides a pyrolysis gas for treatment of additional hydrogen-deficient carbonaceous material. The amount of steam used and the conditions within the water-gas shift reaction zone and gas separation zone are controlled to obtain a steady-state composition of pyrolysis gas which will comprise hydrogen as the principal constituent and a minor amount of carbon monoxide, steam and methane so that no external source of hydrogen is needed to supply the hydrogen requirements of the process. In accordance with a particularly preferred embodiment, conditions are controlled such that there also is produced a significant quantity of benzene as a valuable coproduct.
