(Jan 24) The 71st Hiroshima University Biomass Evening Seminar(The 46th Hiroshima University ACE Seminar)

Biomass Project Research Center, Hiroshima University, and HOSTY Association are co-organizing the Hiroshima University Biomass Evening Seminar. This seminar covers topics from the fundamentals of biomass to the latest information so that it can contribute the activities on biomass in this district. The 71st seminar will be held as follows. Please join.

“Characteristics of Mineralization of Organic Phosphorus and Gasification of Organic Material under Hydrothermal Condition”
Due to the recent problem about depletion of phosphate rock, researches about recovery of phosphorus from the waste like sewage sludge and utilization of them as alternative resource of phosphate rock has been conducted. Hydrothermal treatment is expected as the one of treatment for sewage sludge, but decomposition characteristics of organic phosphorus under hydrothermal treatment hasn’t been elucidated. In this study, hydrothermal treatment of DNA, which is one of major organic phosphorus contained in sewage sludge, was conducted. As the result, the characteristics of mineralization and gasification was elucidated.

“In-situ Mass Spectrometry for Hydrothermal Reaction Field”
Hydrothermal pretreatment is important for production of the second generation bioethanol. Thus, knowledge on the reaction occurring during pretreatment is needed. In previous study, Duangkaew et al. discovered substances that have not been detected in high pressure and high temperature condition using in-situ mass spectrometry, showing its effectiveness on reaction analysis for hydrothermal pretreatment. However, the allowable pressure was limited by the nozzle spray. In this study, we added needle valve to enable analysis at pressure and temperature higher than that of previous study.

[Biomass Lecture Series]  “Thermochemical conversion”
◆Lecture: Yukihiko MATSUMURA
Professor, Graduate School of Engineering, Hiroshima University

While depletion of energy resources is regarded as a problem, biomass resources produced by living organisms by using solar energy are attracting attention as renewable energy along with natural energy such as wind power and sunlight. For effective utilization of biomass, it is necessary to convert it to secondary energy by appropriate conversion. There are three types of biomass energy conversion: 1) physical conversion, 2) thermochemical conversion, and 3) biochemical conversion. In this evening seminar, we will introduce the thermochemical conversion of biomass.

We will hold the discussion meeting from 18:00 (800 JPY needed). Join this meeting, too if you are available.
