PRINCIPAL DATA ON THE FOAMING PROCESS FOR THE HYDRO-
CARBON SYNTHESIS
By Michael
|
February 27, 1943, Mi/K1 |
| Process: | The gas is forced into a sump filled with paraffin produced in the reaction and containing colloidal iron (a filter plate is used with a pore width of 0.15 mm. | |
| Heat removal: | The sump is cooled by making the contents circulate through a relatively small outside cooler (heat transfer from liquid). Permissible heat rise 10°C. One sump circuit in about 3 minutes. | |
| Reactor Construction: | An empty vertical cylinder 8 mm high which contains in the bottom part a number of foaming plates (of granular quartz, held together by glass). A small vessel, in which the sump is degased, adjoins the reactor. | |
| Catalysts: | Iron from iron carbonyl (or else obtained by precipitation) ground in oil to a particle size of 2 . 2 percent alkali (borax) added. 300-350 kg Fe/cbm of sump. | |
| Synthesis gas: | CO : H2 = 5 : 4 | |
| Pressure: | 20 atm. | |
| Temperature: | 250°C | |
| Production: | 0.30 - 0.35; if the gas is recirculated, with a CO2 scrubber 0.40 - 0.45 | |
| Products: | Gasol | 8 - 10 percent |
| Gasoline, -200°C | 45 " | |
| Middle oil, 200 - 350°C | 30" | |
| Paraffin, 350°C | 15" | |
| Gasification, | abt. 5" | |
| Properties of Products: | Refined gasoline, O. N. | 62 |
| Refined gasoline, with 0.09 percent Pb, O. N. | 76 | |
| Middle oil (Diesel oil) C.N. | 70 | |
| Olefines: gasol | 75 percent | |
| gasoline | 65 - 70 " | |
| middle oil | 50" | |
| Yields: | 175 g liquid and solid products per cbm utilized gas, 160 g liquid and solid products per ncbm gas (90% convers.). | |
| Applications: | 65 percent of the gasoline can be converted to alcohols by the oxo process (lacquer section). 40-50 percent of the middle oil gives sulfonates with H2SO4 (detergents). | |
| Experiments: | 1.5 cbm reactors with seven months operation. Longest continuous operations - three months. No more difficulties are being experienced. | |
| Industrial units: | Reactors 8 m high, 2 m diam., 30 cbm capacity, or else reactors 8 m high, 2.5 m diameter, cap. 45 cbm. | |
| New experimental reactor: | 8 m high, diam. 1.50 m, cap. 13.5 cbm, for 5 te/day. | |
