COAL HYDROGENATION STUDY-FINAL REPORT - PHASE 2

BITUMENS ARE PRODUCED FOR HIGHWAY CONSTRUCTION BY THE HYDROGENATION OF VARIOUS PULVERIZED COALS DISPERSED IN VARIOUS CARRIERS USING DIFFERENT CATALYTIC, PRESSURE, TEMPERATURE AND TIME TREATMENTS IN A LABORATORY REACTOR. DATA TABULATIONS ARE INCLUDED PERTAINING TO THE MATERIALS, PROCESSES, RESULTANT PRODUCTS AND THE VOLATILE, RHEOLOGICAL AND ADHESIVE CHARACTERISTICS OF THESE PRODUCTS. INFORMATION PERTAINING TO THE KINETICS OF THE PROCESSESS AND MECHANISMS OF REACTIONS ARE INCLUDED. IT WAS FOUND THAT A SUPERIOR PRODUCT COULD BE OBTAINED FROM A CHARGE CONSISTING OF FOUR PARTS LOW TEMPERATURE DISTILLATE, A COAL TAR FRACTION PRODUCED BY CF&I CORP., TO ONE PART ELKOL COAL, IMPREGNATED WITH 0.5 WEIGHT PERCENT FERROUS IRON. THE STABILITY OF THE BITUMEN PRODUCT AS MEASURED BY ITS RETAINED VISCOSITY INCREASED AS THE REACTION TEMPERATURE, TIME AND HYDROGENATION PRESSURE INCREASED. THE EFFECT OF VARIOUS CARRIERS IN CONVERTING THE COAL TO BENZENE-SOLUBLE PRODUCTS CORRELATED WITH THE SOLUBILITY PARAMETER OF THE CARRIER USED AND ITS HYDROGENATION DONOR CAPABILITIES. A MIDDLE BOILING RANGE, HYDROGENATED COAL-DERIVED CARRIER APPEARS TO GIVE THE MAXIMUM YIELD OF HIGH QUALITY BITUMEN AND REQUIRES NO CATALYST. THE VISCOSITY TEMPERATURE SUSCEPTIBILITY OF THE BITUMENS PRODUCED RANGED FROM 4.2 TO 5.2. INCREASED CONVERSION WAS OBTAINED WITH INCREASED AMOUNTS OF FERROUS IRON CATALYST, UP TO A CONCENTRATION OF 1.0 WEIGHT PERCENT OF THE COAL. THE RETAINED VISCOSITY /RATIO OF VISCOSITY OF A MODIFIED THIN FILM OVEN TEST RESIDUE OF THE BITUMEN PRODUCT AND THE VISCOSITY OF THE BITUMEN PRODUCT/ APPEARED TO INCREASE AS THE CARBON CONTENT OF THE COAL INCREASED. RANDOM VARIATIONS WERE FOUND IN THE VISCOSITY TEMPERATURE SUSCE- PTIBILITY OF THE PRODUCTS. THE PRODUCTION OF HYDROGENATED COAL BITUMENS AS BY-PRODUCTS FROM A COAL CONVERSION PROCESS IS FEASIBLE.
