1-1.事業概要
本事業では、食料と競合しないセルロース系バイオマスを用い、バイオマスからガス化、FT(Fischer-Tropsch)合成を経て液体炭化水素を得るBTL(Biomass to Liquid)プロセスに関する研究開発を実施する。BTLは、バイオマスの賦存量や収集面の制約からGTL(Gas to Liquid)やCTL(Coal to Liquid)と比較して小スケールになるため、装置コスト、運転コストを極力低減することが望ましい。そこで、従来実施されてきた高圧条件下、スラリー床式反応器などでのFT合成と比較して、さらに高性能なFT 触媒を開発することにより、低圧下、固定床式のFT合成プロセスの実現を目指して検討を実施中である。
英文要約Title : New Energy Technology Development Project. Development of Technology for High-efficiency Conversion of Biomass and Other Energy. Development of Preparatory Basic Bioenergy Technologies. Development of BTL Process Using Fischer-Tropsch Synthesis Catalyst for Low-pressure Fixed-bed Reactor. (FY2009-FY2012) FY2011 Annual Report

In this project, R&D of BTL (Biomass to Liquid) process to obtain liquid hydrocarbon through FT (Fischer-Tropsch) synthesis and gasification of biomass has been carried out using cellulosic biomass which does not compete with provisions. After April 2011, development of catalyst combination of FT catalyst and zeolite for the production of lighter hydrocarbons has proceeded for the simplification of generally equipped up-grading (UG) process such as hydrocracking of wax. (a) Development of FT catalyst (Cosmo Oil): The combination of FT catalyst and zeolite is expected to have effect on the control of declining catalyst activity by the promotion of synthesis lighter fraction and control of synthesis heavier wax fraction in addition to simplification of UG process mentioned above. The location of FT catalyst close to zeolite should be important for the promotion of synthesis lighter fraction and control of synthesis heavier wax fraction. Therefore, it was figured out that molded integration FT catalyst prepared with the mixture of FT catalyst powder and zeolite powder showed excellent activity instead of the mixture of molded FT catalyst and molded zeolite. (b) Analysis for reaction mechanism of FT catalyst (AIST): Through the analysis of the situation of wax accumulation on FT catalyst (TPR, XRD, TG/DTA, FT-IR), we found there were several types of accumulated materials and it was possible to remove a part of accumulated materials by hydro-treatment. And effectiveness of the integration with zeolite was confirmed by the analysis of zeolite acidity (NH3-TPD measurement) and situation of wax accumulation on several catalysts (Fresh or Spent / Mixture or Integrated). (c) Design of a bench reactor and its evaluation (Cosmo Oil): The collection of process data with the former bench reactor has been planned to prepare for conceptual design of 1BPD scale FT reactor. However, thermal conductivity in this bench reactor is very different from the real scale reactor due to its small size and slow feed gas velocity. The long scale reactor (4m-length) was introduced to obtain more reliable process data with high feed gas velocity and suitable thermal conductivity. Furthermore, the FT bench reactor was remodeled in terms of heat insulation, pressure gauge and preheat of feed gas. On the other hand, the scale-up simulation using collected bench data was introduced. (d) Evaluation of FT synthetic oil and general evaluation of BTL (TOYOTA): For oil containing gasoline fuel evaluation (vehicle test) scheduled in FY2012, test methods and the conditions were considered. The fuel for vehicle test would be prepared by adding oil derived from the bench reactor to commercial regular gasoline with a certain ratio to adjust JIS regular gasoline grade. The check points for vehicle test to compare with commercial gasoline would be combustibility, fuel consumption and exhaust gas composition.
