项目摘要

The present joint research which aims at the development of highly efficient conversion processes for Victorian Brown coal has started in 1988 and, in that year, five researchers were sent to Australian institutions to do experimental works. The results obtained were further developed at the related Universities in Japan in 1989 and 1990. In addition, two researchers were sent to Australia by the present program. For consultation, six Australian scientists were invited to Japan in 1989 and four Japanese members visited Australia in 1990. In each time, the program was discussed and views on coal research were exchanged. Valuable results were obtained as follows.(1) The upgrading of liquefied oils was studied and high surface area ceramics were shown to be appropriate for the support of CoMo catalyst.(2) An analysis of liquefaction of coals using model substances indicated that origin of long-chain alkanes and alkenes was aromatic esters.(3) Catalysts in flash pyrolysis were found to promote the decomposition of oxygen-containing functional groups on coal surfaces as well as secondary reactions in gas phase.(4) Changes in surface state of brown coal during heating were investigated and the role of these on the catalytic gasification of char was elucidated.(5) A new process for producing a high performance active carbons from brown coal for removing SOx and NOx was developed.(6) Proton Magnetic Resonance Thermal Analysis was used to see the changes in coal structure during heating and new mobile phases were detected. Also the reaction processes between brown coal and added materials were clarified.(7) Products from oxidation of brown coal in alkaline medium with oxygen was separated effectively using high performance liquid chromatography.The program gave prospect of new conversion processes and greatly contributed to the mutual understanding between the two parties.

目前的联合研究始于1988年，旨在开发维多利亚褐煤的高效转化工艺，当年，五名研究人员被派往澳大利亚机构进行实验工作。 1989年和1990年，日本相关大学进一步发展了所获得的成果。此外，本项目还派遣了两名研究人员前往澳大利亚。 1989年邀请6名澳大利亚科学家访问日本，1990年邀请4名日本成员访问澳大利亚，每次都讨论了计划并交换了对煤炭研究的看法。获得了以下有价值的结果：(1)研究了液化油的改质，证明高比表面积陶瓷适合作为CoMo催化剂的载体。(2)利用模型物质对煤的液化进行分析，表明长链烷烃和烯烃的来源是芳香酯。(3)发现闪热解催化剂可以促进含氧分解。 (4)研究了褐煤在加热过程中表面状态的变化，阐明了这些变化对焦炭催化气化的作用。(5)开发了一种用褐煤生产高性能活性炭去除SOx和NOx的新工艺。(6)利用质子磁共振热分析观察加热过程中煤结构的变化，并开发了新的流动相。检测到。 (7)利用高效液相色谱法对褐煤在碱性介质中与氧的氧化反应产物进行了有效分离。该方案对新的转化工艺进行了展望，为双方的相互了解做出了贡献。
