Inventors:

Thomas A. Weil - Naperville IL

Assignee:

Standard Oil Company (Indiana) - Chicago IL

International Classification:

C07C 8506

US Classification:

564402

Abstract:

A process for the preparation of 1,4-phenylenediamine from 1,4-dihydroxybenzene at a temperature within the range of from about 300. degree. C. to 450. degree. C. and a pressure of from atmospheric to 3000 psig in the presence of an aminating agent, an inert hydrocarbon and an acidic alumina catalyst. p-Aminophenol can be aminated to 1,4-phenylenediamine with the same process.

C10G 100

US Classification:

585240

Abstract:

A process for production and recovery of hydrocarbons from hydrocarbon-containing whole plants in a form suitable for use as chemical feedstocks or as hydrocarbon energy sources which process comprises: (a) pulverizing by grinding or chopping hydrocarbon-containing whole plants selected from the group consisting of Euphorbiaceae, Apocynaceae, Asclepiadaceae, Compositae, Cactaceae and Pinaceae families to a suitable particle size, (b) drying and preheating said particles in a reducing atmosphere under positive pressure (c) passing said particles through a thermal conversion zone containing a reducing atmosphere and with a residence time of 1 second to about 30 minutes at a temperature within the range of from about 200. degree. C. to about 1000. degree. C. , (d) separately recovering the condensable vapors as liquids and the noncondensable gases in a condition suitable for use as chemical feedstocks or as hydrocarbon fuels.

International Classification:

C12P 1914

C12P 500
C12P 502

US Classification:

435 99

Abstract:

A process for enzymatically converting whole plant biomass containing hydrocarbon-containing laticifers to soluble sugars and recovering hydrocarbons in increased yields which comprises hydrolyzing whole plant cellulosic material in the presence of enzymes, particularly cellulase, hemicellulase, and pectinase, to produce a hydrocarbon product and recovering from the hydrolysis products a major proportion of the cellulase, hemicellulase and pectinase enzymes for reuse. At least some portion of the required make-up of cellulase, hemicellulase and pectinase enzymes is produced in a two-stage operation wherein, in the first stage, a portion of the output sugar solution is used to grow enzyme secreting microorganisms selected from the group consisting of cellulase-secreting microorganisms, hemicellulase-secreting microorganisms, pectinase-secreting microorganisms, and mixtures thereof, and in the second stage, cellulase, hemicellulase and pectinase enzyme formation is induced in the microorganism-containing culture medium by the addition of an appropriate inducer such as biomass. The cellulase, hemicellulase and pectinase enzymes are then recycled for use in the hydrolysis reaction.
