Hydrogen production by the partial oxidation and steam reforming of tar from hot coke oven gas 总被引:1,自引:0,他引:1
Masaki Onozaki Koji Watanabe Takao Hashimoto Hitoshi Saegusa Yukuo Katayama 《Fuel》2006,85(2):143-149
Hot coke oven gas (COG) with a temperature of about 1050 K was produced from a test unit for coke production, the capacity of which was 80 kg of coal. The COG was introduced into an experimental unit with a tar converter where oxygen and steam were injected. Over 98% of the total carbon in the hot COG was partially oxidized, reformed with steam and converted to hydrogen and CO. About 1 Nm3/h of hydrogen was continuously produced for 5 h in this experiment. The experimental results suggest that three to five times the amount of hydrogen and CO that were present in the original COG could be recovered by this technology, utilizing the heat of the hot COG for the reaction. The feasibility study showed that hydrogen can be produced by this technology at a lower cost and higher efficiency than by the separation of cold COG. 相似文献

New technical processes in coal chemistry . The most important commercial basic processes of primary coal conversion are carbonisation, gasification, and hydrogenation. Some 450 mio t/a of coal are converted by coking in horizontal slot type ovens to 350 mio t/a of metallurgical coke for the reduction of iron ore in blast furnaces, coke oven gas, and some 20 mio t/a of coke oven benzole and coal tar as raw material for aromatics. The coke ovens are being developed to high-capacity coking reactors. New second generation processes for the gasification of coal and lignite have advanced to an industrial scale. A vapor-phase hydrocracking refining step has been integrated within the further developed process for the catalytic liquid-phase hydrogenation of coal. Plasma pyrolysis of high-volatile bituminous coal investigated on a semi-industrial scale yields acetylene. Pressure hydropyrolysis of coal currently being tested on a pilot plant scale generates high-aromatic liquid products. New processes for the upgrading of such liquids have been developed above all for aromatics from coal tar, e. g. for the production of naphthalene derivatives, and the conversion of polycyclic aromatic hydrocarbons into the technical carbon products carbon black, electrographite, carbon electrodes, and carbon fibres. 相似文献

Study on a multifunctional energy system producing coking heat, methanol and electricity 总被引:1,自引:0,他引:1
A multifunctional energy system (MES) capable of consuming coke oven gas (COG) and coal, and simultaneously producing coking heat, methanol and electricity, was subject to an exergy analyses based on Energy Utilization Diagrams (EUDs). In this system a coal-fired coke oven is adopted to produce coke and COG, where non-coking coal is burned to supply thermal energy to the coking process. The COG and coal gas gasified from coal in a gasifier, were mixed to produce syngas for methanol synthesis. Since COG rich in hydrogen and coal gas rich in CO, the mixture of COG and coal gas can easily adjust the mole ratio of CO to H2 of syngas instead of the conversional reforming and shift processes. The active component of syngas is firstly converted into methanol and then the rest is introduced to a gas turbine for power generation. As a result, the overall efficiency of the MES system is about 62.3%, and its energy savings ratio is about 15% comparing with individual systems. The paper provides a new approach to use coal more efficiently and cleanly. 相似文献
