20150021158 | COAL DRY DISTILLATION DEVICE - The coal dry distillation device is provided with a dry distillation device of their invention main body which is provided with an inner tube to which the dry coal is supplied and an outer tube which covers the inner tube, and which indirectly heats the dry coal in the inner tube by means of a heating gas supplied to the outer tube and generates dry-distilled coal and dry distillation gas. This coal dry distillation device is provided with a mercury adsorption suppressing means which suppresses adsorption of mercury contained in the dry distillation gas into the dry-distilled coal, wherein the mercury adsorption suppressing means is an exhaust tube which discharges a gas inside the inner tube. The gas inlet port of the exhaust tube is arranged in a region between the substantially central portion in the longitudinal direction and the coal heating unit outlet in the inner tube. | 01-22-2015 |
20150027872 | MODIFIED COAL PRODUCTION EQUIPMENT - Modified coal production equipment comprising: first oxygen adsorption speed measuring means ( | 01-29-2015 |
20150175890 | COAL DRY-DISTILLATION DEVICE AND MODIFIED COAL PRODUCTION EQUIPMENT USING SAME - A rotary kiln-type coal dry-distillation device that: rotatably supports an inner tube inside an outer tube; supplies heating gas to the interior of the outer tube; moves dried coal from one end side of the inner tube to the other end side, and agitates and dry-distills the dried coal under heat by supplying the dried coal from the one end side of the inner tube to the interior, and rotating the inner tube; sends out dry-distilled coal and dry-distilled gas from the other end side of the inner tube; and has provided therein a pulverized coal supply device that supplies pulverized coal having a particle diameter of no more than 100 μm to the interior of the inner tube, such that the volume of the pulverized coal is 1-10 wt % relative to the amount of dry-distilled coal sent from the other end side of the inner tube. | 06-25-2015 |
