Chemicals from Hydrocarbons by Vapor Phase Oxidation

Abstract

Hydrocarbons can be readily oxidized in the vapor phase and noncatalytically to make chemicals under conditions of excellent temperature control when the reaction is carried out in the presence of a dispersion of fine inert solids DURISG the more than 20 years of work on vapor phase oxidation in this laboratory ( 2 ) : interest has centered on the development of a suitable reactor. the production and identification of chemicals resulting from hydrocarbon oxidations, and the mechanism of the oxidation reaction. Altogether; about 35 pure hydrocarbons have been studied.Eight different types of reactors (including open tubes, dense beds, packed columns employing highboiling inert liquids for temperature control in direct contact with the reactants, a transfer line reactor, and a three-stage alternate bed and void type of reactor) \vere built and evaluated > LIFT LINE

Oxidation and Oxidative Dehydrogenation of Ethane and Propane

“…The basic apparatus has been described (Fenske et al, 1966;Jones and Fenske, 1959). The basic apparatus has been described (Fenske et al, 1966;Jones and Fenske, 1959).…”

Vapor Phase Oxidation of Aromatic Hydrocarbons.

“…The apparatus has been described (3). The solids circulated for heat removal consisted of fused zircon silica (The Carborundum Co.) about 300 microns in diameter.…”

“…The carbon-forming propensities of fuels have usually been measured and compared by determining the maximum rate at which each fuel could be burned in a specially designed apparatus (3,4,5) without smoking. The figure of merit may be the actual limiting burning rate or the corresponding flame height.…”

Conversion of Gas Oils by Oxidation.

“…THE UTILITY of noncatalytic vapor phase oxidation of hydrocarbons in a raining-solids-type reactor (5)(6)(7) has been extended to heavier compounds, namely gas oils, for the production of olefins, oxygenated compounds, and fuels. This article reports the results obtained from the vapor phase oxidation of selected gas oil feedstocks and compares the results with data from the thermal and catalytic cracking of similar feedstocks (4).…”

“…EXPERIMENTAL Apparatus. The basic apparatus has been described (6). The solids used in the present work were zircon silica (The Carborundum Co.) of 35 to 40 mesh size.…”
