A STUDY OF THE HYDROGENATION OF A WYOMING COAL

A REPORT IS PRESENTED ON WORK DONE IN HYDROGENATING A COAL FOR PRODUCTION OF BITUMENS THAT MIGHT BE SUITABLE FOR USE IN HIGHWAY CONSTRUCTION. IT CONSISTS LARGELY OF DESCRIPTIONS OF MATERIALS, PROCESS CONDITIONS, YIELDS, AND CONTAINS INFORMATION ON THE KINETICS OF THE PROCESSES AND ON SEVERAL MECHANISMS TO EXPLAIN PRODUCT FORMATION. SOME INFORMATION IS ALSO GIVEN TO INDICATE THE CHARACTER OF THE BITUMENS PRODUCED UNDER DIFFERENT PROCESS CONDITIONS. THE BITUMENS APPEAR TO HAVE ADHESIVE PROPERTIES COMPARABLE TO THOSE OF ROAD TAR AND SUPERIOR TO THOSE OF PETROLEUM ASPHALTS. VISCOSITY-TEMPERATURE SUSCEPTIBILITY PROPERTIES AND PERFORMANCE IN A MODIFIED THIN FILM OVEN TEST OF THE HYDROGENATED PRODUCT APPEAR TO BE INTERMEDIATE BETWEEN THOSE OF ASPHALT AND ROAD TARS. IT IS CONCLUDED THAT PRODUCTION OF A ROAD BINDER FROM A WYOMING COAL BY A HYDROGENATION PROCESS IS FEASIBLE. /BPR/
