Reactive catalytic fast pyrolysis with atmospheric pressure hydrogen improved yield and quality of the resulting bio-crude.
Optimizing catalysts and reaction conditions for transalkylation as well hydrodeoxygenation reactions in a hydropyrolysis process while minimizing demethylation may improve carbon yield energy recovery the liquid product. Pyrolysis vapor model compound were investigated fixed bed reactor at 350–450 °C, 1.7–15 bar (10–200 psig), with 14–60 mol % hydrogen feed gas mixture to determine pathways under range of conditions. Anisole phase studied over commercially available Ni-based hydrotreating...

A variety of measurements using a differential scanning calorimeter were used to probe how single-walled carbon nanotubes (SWCNTs) affect polymer dynamics associated with the glass transition. Tubes dispersed in N,N-dimethylformamide containing dissolved polystyrene, and precipitation was quickly forced by addition large amounts water. The percolation threshold found be less than 0.5 wt %, indicating good dispersion tubes. transition temperature (Tg) increased at low nanotube fractions...
Catalytic hydropyrolysis of loblolly pine was studied in a high-pressure fluidized bed reactor using NiMo hydrotreating catalyst. Hydropyrolysis temperature (375–475 °C) influenced the product distribution, composition, H2 consumption, and process carbon efficiency. The material balances ranged from 84% to 106% with an average 91%. organic liquid yields including C4–C6 gases 20 wt % 24 %, gas were between 11 27 %. yield solids varied 8 26 Catalyst stability at 450 °C 20.68 bar (300 psig)...
Reactive catalytic fast pyrolysis (RCFP) of biomass with atmospheric pressure hydrogen is a promising route for the deoxygenation vapors while retaining high carbon yields in bio-crude. RCFP process development was accomplished bench-scale bubbling fluidized-bed reactor situ catalyst configuration. Results are presented that highlight impact temperature, weight hourly space velocity (WHSV), reaction pressure, and time on stream hydrodeoxygenation different oxygen-containing species produced...
We report the hydrogen evolution reaction (HER) with molybdenum diselenide (MoSe2) and its reduced graphene oxide (rGO) hybrids synthesized by a microwave process followed annealing at 400 °C. The content of GO was varied to understand role in electrocatalytic activities. Electrochemical performance as-synthesized annealed catalysts underscores (i) requirement catalytic activation samples, (ii) an apparent shift onset potential as result annealing, (iii) striking changes Tafel slope well...
Abstract At RTI, we are developing a catalytic fast pyrolysis process with new solid acid catalyst, the performance of which has been evaluated in pilot‐scale reactor using loblolly pine. More robust technology development requires deeper understanding influence feedstock properties defined by organic liquid yield and composition. Seven types woody herbaceous biomass were tested 2.54 cm diameter fluidized‐bed reactor. This study shows that product distribution biocrude composition vary...
A process for the utilization of CO2 conversion ethylene to oxide has been studied greenhouse gas life cycle analysis and compared commercial production which uses oxygen from an air-separation unit. Mixed- metal oxides were identified tested in a micro-reactor yield. The mixed-metal shown produce under moderate conditions.
