石炭水素化分解生成オイルのGC-MS/MS分析

横山 晋, 中村 久志, 伊藤 好江, 佐藤 正昭, 真田 雄三, 鈴木 優, 町原 勉

抄録

In a previous paper, coal hydrogenation oil was subjected to GC-MS analysis for the elucidation of the chemical structure for its individual components. However, the mass spectra often had an overlap of some components and the interpretation of the spectra became very difficult.
In this study, GC-MS/MS analyses, which has a superior efficiency by the combination of GC and mass separations, were applied to resolve the problems mentioned above of the GC-MS method. After the first separation of the monoaromatic fraction by a high resolution capillary column GC, specific mass numbers of the components belonging to the homologous series of the compound type were selected for the second separation into unimolecular parent ion. Daughter mass spectra derived from the unimolecular parent ion were obtained by scanning the daughter mass range at the second mass analyser.
Main peaks of Z number mass chromatogram of Z=-8, mononaphthenobenzenes, were measured for their daughter mass spectra. Acquisition of mass spectra with arrangement of Z number mass chromatorams are an effective procedure for the identification of individual compounds of coal liquid and a database of mass spectra.

HYCOL石炭ガス化パイロットプラントの運転研究成果

上田 史麒, 吉田 信夫

pp. 731-736

DOI:

10.3775/jie.74.731

抄録

An advanced coal gasification pilot plant, with a capacity of 50tons coal par day, located in Sodegaura, Chiba, Japan successfully completed its three-year operation program on April 15, 1994. The program proved the fundamental features of the HYCOL coal gasification technology ; an entrained flow, oxygen blow, one chamber with two-step spiral flow multi-burners.
The pilot plant completed ten runs, logged 2164 hours of operation, including a 1149 hour long and uninterrupted run, and four different coals. These results confirmed the process viability and validated study efforts by New Energy and Industrial Technology Development Organization and Research Association for Hydrogen-from-coal Process Development.
Operations at several oxgen/coal ratios confirmed favorable temperature profiles of the gasification section as envisioned in the design concept.
Targets of carbon conversion rate (98% +) and cold gas efficiency (78% +) were achieved simultaneously.
Direct hot char recycle was stable and uninterrupted during 1149 hours.
Sub-bituminous and bituminous four coals were gasified including an on fly mode feed coal switching and demonstrated addition of fluxing agent.
Problems due to ash component experienced during the shake down phase were successfully overcome.
