    • PURPOSE:To gasify fine carbonaceous pitch with extremely high fixed carbon content effectively while keeping a large amount of paricle coke precipitation, by bringing the fine carbonaceous pitch into contact with a fluidized high- temperature porous fine powder so that it is gasified. CONSTITUTION:Fine powder of fine liquid droplet carbonaceous pitch (prefer ably, >=90wt% pitch having 1-5,000mum representative diameter) is brought into contact with high-temperature porous fine powder which is fluidized with a gas containing steam and/or molecular oxygen, and gasified usually at 750-1,000 deg.C. Fine spherical particles having 0.2-1.5cm /g pore volume, 5-1,500m /g specific surface area, 10-10,000Angstrom average pore diameter, and 0.025-0.25mm weight-average diameter, and having properties kept stably at temperature used, is used as the fine powder. EFFECT:Use of a large amount of fluidized articles is not required.

    • PURPOSE:To permit to improve a gasification efficiency without an increase of O2 volume by adapting a mechanism in which a feeder inlet of a gas contining O2 and a feeder inlet of pulverized coals with an inert carrier gas is adapted to intersect each other in respective feeding directions within a range of the specified angle. CONSTITUTION:A blowing-off direction of N2 carrier, pulverized coals sent from its feeding path 21 and a blowing-off direction of O2 jet nozzle A makes an intersecting angle theta3, which is adapted to be in the mechanism, 90-theta2=30-45 deg.. By this angle, O2 blown-off from the jet nozzle 24A is instantaneously mixed with pulverized coal mixture, causing prevention of O2 consumption due to atomosphere gas. Also by deciding angle of O2 45-60 deg., the gas rolling-in effect is obtained and the spreading angle of the pulverized coal mixture become wider, consequenty the gas mixing feature is improved. According to this mechanism, the un-burnt amount of pulverized coal owing to blow-by becomes smaller as well as the consumption volume of O2 due to coalgas, which make it possible to improve the conversion rate of the carbon, to minimize for lowering a calorific value of the gas and to improve a gasification efficiency thereof.
    • 目的:通过适应一种机制,允许改善气化效率而不增加O2体积,其中在惰性载气下连续输送O2的气体进料口和粉煤进料口的进料口在相应的进料 方向在指定角度范围内。 构成:N2载体的吹出方向,从其输送路径21送出的粉煤和O2喷嘴A的吹出方向,使适于机械的90°θ= 30°的交叉角θ3 -45°。通过该角度,从喷射喷嘴24A吹出的O2与粉煤混合物瞬间混合,从而防止由于大气气体引起的氧消耗。 另外通过决定O2的角度为45-60度,获得气体滚压效果,并且粉煤混合物的扩展角度变宽,从而提高了气体混合特性。 根据该机理,由于气化造成的粉煤的未燃烧量变小,因此,由于煤气的消耗量,能够提高碳的转化率,因此可降低碳含量 气体的发热量,提高气化效率。
