Carbonization, hydrogenation, and incineration studies are being made on a solid municipal refuse that is highly cellulosic. Carbonization is being done batchwise at 500 deg c (932 deg f), 750 deg c (1,382 deg f) and 900 deg c (1,650 deg f), and the yields and composition of the product chars, tars, oils, and gases are being determined. Depending on the carbonization temperature, a ton of dry refuse would yield up to 18,000 cu ft of gas with 6 million btu available, up to 230 lb of char with 1.8 million btu available, and up to about 6 gal of tar and light oil. Hydrogenation of the same refuse is being effected with carbon monoxide and water batchwise at 4,000 psig and 380 deg c (716 deg f). Initial results indicate that a ton of dry refuse would yield about 2.4 Barrels of oil that is largely paraffinic. Comparative hydrogenation studies are also being made with molecular hydrogen, with and without catalysts. Using tangential overfire air to produce a vortex flow pattern above the charge, a continuous flow of shredded refuse is being incinerated, aiming to obtain basic design data on the optimum air velocity and nozzle geometry for maximum combustion efficiency and particulate retention, and for minimum excess air.
