Abstract

Organic matter (OM) was isolated from two marine oil shales, ElLajjun and Julia Creek, using NaOH-HCl and humin and humic acid fractions separated. Two treatments were required to reduce humin ash yield to below 11 wt% db. The humin yield of the autoclave method was 80 wt% of OM (dry mineral-matter-free, dmmf), compared to only 20–60 wt% dmmf for the oven method, possibly due to the increased NaOH solution strength and some oxidation. Oven and autoclave methods both gave humin similar in chemical structure to shale OM, regardless of yield. This similarity has implications as to shale OM structure.

利用烤箱和密封高压灭菌技术，用naoh-hcl法从两种海洋油页岩中分离有机物

采用NaOH-HCl、腐植酸和腐植酸分离馏分，从ElLajjun和Julia Creek两种海相油页岩中分离有机质。要将人灰分产量降低到11% db以下，需要两个处理。高压灭菌法的人类素产率为80 wt%的OM(无干矿物物质，dmmf)，而烘箱法只有20-60 wt%的dmmf，可能是由于NaOH溶液强度的增加和一些氧化。无论产量如何，烘箱法和高压灭菌法都能得到与页岩有机质相似的化学结构。这种相似性对页岩有机质结构具有启示意义。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
