Hydrocarbon Fuel Production from Lignocellulosic Biomass by Solvolysis and Catalytic Cracking
Utilization of lignocellulosic biomass for alternative fuels requires efficient and low-cost processes for deoxygenation and conversion to hydrocarbons. We propose a 2-step biomass conversion process consisting of solvolysis pretreatment and co-processing with heavy petroleum oil in catalytic cracking. High liquefied yield (> 90 C%) was achieved by solvolysis in guaiacol and water with acetic acid catalysts. Bio-oil was mainly converted to gaseous hydrocarbons and coke by co-processing with model heavy oil (n-eicosane). Deoxygenation pathway to H2O formation was accelerated by enhancing hydrogen-transfer activity even without supplying hydrogen. Hydrogen-transfer deoxygenation proceeded preferentially to olefin hydrogenation. Consequently, enhancing hydrogen-transfer activity in the co-processing of bio-oil and heavy petroleum oil was effective for efficient deoxygenation without lowering octane rating.ArticleJOURNAL OF THE JAPAN PETROLEUM INSTITUTE.61(5):302-310(2018)journal articl
THE WIDE-ANGLE OUTFLOW OF THE LENSED z=1.51 AGN HS 0810+2554
We present results from X-ray observations of the gravitationally lensed z - 1.51 active galactic nucleus (AGN) HS 0810+2554 performed with the Chandra X-ray Observatory and XMM-Newton. Blueshifted absorption lines are detected in both observations at rest-frame energies ranging between similar to 1 and 12 keV at greater than or similar to 99% confidence. The inferred velocities of the outflowing components range between similar to 0.1c and similar to 0.4c. A strong emission line at similar to 6.8 keV that is accompanied by a significant absorption line at similar to 7.8 keV is also detected in the Chandra observation. The presence of these lines is a characteristic feature of a P-Cygni profile supporting the presence of an expanding, outflowing, highly ionized iron absorber in this quasar. Modeling of the P-Cygni profile constrains the covering factor of the wind to be greater than or similar to 0.6, assuming disk shielding. A disk-reflection component is detected in the XMM-Newton observation accompanied by blueshifted absorption lines. The XMM-Newton observation constrains the inclination angle to be <45 degrees at 90% confidence, assuming that the hard excess is due to blurred reflection from the accretion disk. The detection of an ultrafast and wide-angle wind in an AGN with intrinsic narrow absorption lines (NALs) would suggest that quasar winds may couple efficiently with the intergalactic medium and provide significant feedback if ubiquitous in all NAL and broad absorption line (BAL) quasars. We estimate the mass-outflow rate of the absorbers to lie in the range of 1.5-3.4M(circle dot) yr(-1) for the two observations. We find that the fraction of kinetic to electromagnetic luminosity released by HS 0810+2554 is large (epsilon(k) = 9(-6)(+8)), which suggests that magnetic driving is likely a significant contributor to the acceleration of this outflow.ArticleASTROPHYSICAL JOURNAL.824(1):53(2016)journal articl
