Title: Potential of producing high octane additives and hydrogen from biomass-derived oils

Abstract

In the early approach, the upgrading of biomass-derived oils (BDO) to hydrocarbons was carried out using typical hydrotreating catalysts such as Co-Mo/Al{sub 2}O{sub 3}. The major drawback was the high operating cost due to the addition of hydrogen and high pressure requirements of the process. On the other hand, these studies have shown that the use of catalysts such as HZSM-5, HY, silicate, molecular sieves, silica-alumina and mordenite for upgrading such oils does not require hydrogen and can be performed at atmospheric pressure. Also, these studies have shown that the product slate can be dramatically altered by changing the characteristics or functionality of the catalyst. Furthermore, HZSM-5 and silica-alumina were found to be the most effective catalysts for producing aromatic and aliphatic hydrocarbons, respectively. This presentation includes the upgrading of BDO over HZSM-5, silica-alumina and HS-Mix (a physical mixture composed of 20 wt % HZSM-5 and 80 wt% silica-alumina) catalysts. The BDO was produced by rapid thermal processing (RTP) of a commercial oak sawdust. The upgrading of the oil was performed at atmospheric pressure in a fixed bed microreactor. Char, which was one of the products from this upgrading process, was found to be reactive. Steam gasification of this charmore » was carried out at atmospheric pressure. The overall objective was to investigate the potential for the production of hydrogen and high octane additives from a biomass-derived oil.« less
