    Abstract: A PROCESS OF PYROLYZING COAL, BY HEATING IT IN A FIRST STAGE FLUIDIZED BED IN THE ABSENCE OF ADDED OXYGEN AND VAPORS FROM COAL PYROLYSIS CONTAINING MATERIAL CONDENSABLE AS OILY LIQUID, AT A TEMPERATURE BELOW THE FUSION TEMPERATURE, BUT SUFFICIENTLY HIGH TO REMOVE SOME VOLATILES FROM THE DRY COAL UNTIL ABOUT 1-10% OF THE DRY COAL ARE REMOVED OVERHEAD AS VOLATILES; IN AT LEAST A SECOND DEVOLATIZING STAGE, PASSING THE THUS TREATED COAL INTO AT LEAST ONE OTHER FLUIDIZED BED AT A TEMPERATURE ABOVE THAT OF THE FIRST BED AND BELOW THE FUSION POINT OF THE SOLIDS FED TO THAT STAGE, IN THE ABSENCE OF OXYGEN FOR A TIME SUFFICIENT TO NEARLY REMOVE ALL OF THE VOLATILES FROM THE COAL CONDENSABLE TO OILY LIQUIDS; DIVIDING THE NEARLY DEVOLATILIZED CHAR INTO A PRODUCT STREAM, A RECYCLE STREAM AND A COMBUSTION STREAM; COMPLETELY BURNING THE COMBUSTION STREAM, ENTRAINING THE RECYCLE STREAM IN THE HOT GASES FROM THE COMBUSTION STREAM, SEPARATING THE ENTRAINED RECYCLE CHAR FROM THE HOT GASES, AND RECIRCULATING THE HEATED RECYCLE STREAM INTO THE FINAL DEVOLATIZING STAGE, AND RECOVERING THE CONDENSABLES FROM THE OVERHEADS FROM THE FIRST STAGE AND ALL OF THE DEVOLATILIZING STAGES.

    Abstract: In the process of making synthesis gas in a fluidized bed from carbon and steam, wherein a recirculating stream of carbon from the bed is heated externally of the bed with combustion gases derived by burning carbonaceous solids taken from the bed, using all the fines separated from the synthesis gas withdrawn above the fluidized bed, and such additional carbon from the bed as is necessary to make up the required heat balance, the ash content of the bed is maintained near feed levels by drawing char from the bed, fractionating it to obtain an ash-rich fraction and an ash-poor fraction, returning the ash-poor fraction to the gasifier and sending the ash-rich fraction to the combustor.

    Abstract: This specification discloses a vapor phase process for oxidizing acetaldehyde to peracetic acid, acetic acid being also formed at the same time, in an elongated reaction zone into which oxygen is fed through a plurality of oxygen injection sites spaced along the length of the reaction zone. The reaction gas mixture velocity through the reaction zone in the areas of the oxygen injection sites is maintained in excess of the flame velocity of the reaction gas mixture and the reaction zone temperature is maintained between about 140 DEG C. and about 180 DEG C.
