Bifunctional fixed-bed catalysts improve CFP performance.
Feedstock composition can affect final fuel yields and quality for the fast pyrolysis hydrotreatment upgrading pathway. However, previous studies have focused on individual unit operations rather than integrated system. In this study, a suite of six pure lignocellulosic feedstocks (clean (no bark) pine, whole-tree (including tulip poplar, hybrid switchgrass, corn stover) two blends (equal weight percentages pine/tulip poplar/switchgrass pine/clean pine/hybrid poplar) were prepared...
Pinyon juniper biomass feedstocks, which cover a large acreage of rangeland in the western United States, are being eradicated and, therefore, considered as convenient feedstock for biofuel production. whole (wood, bark, and leaves) were pyrolyzed pilot-scale bubbling fluidized-bed reactor at 450 °C, non-condensable gases recycled to fluidize reactor. Red mud was used situ catalyst pyrolysis pinyon biomass. The products condensed three stages, analyzed physicochemical properties. condenser...
Catalytic fast pyrolysis (CFP) has been considered as a very promising approach for converting lignocellulosic biomass into higher-quality bio-oils followed by hydrotreating to produce fuel-range products. A reactive, robust, and low-cost catalyst is required drive the CFP process. Red mud, side-product produced during refining of bauxite alumina, appears be an effective in situ biomass. In this paper, we report impact reaction temperature on conversion pinyon juniper feedstock using red mud...
Abstract The ability to regulate stem cell proliferation and differentiation has relevance in numerous medical applications, including devices, tissue engineering, regenerative medicine. To control cellular behavior at the biomaterial or scaffold interface, many studies have employed surface modifications that mimic extracellular matrix. Strikingly absent is immobilization of cell‐surface ligands surface. One cell‐to‐cell signaling pathway been shown development fate Notch pathway. Recently,...
This paper reports on the catalyst stability of hydrotreatment HTL (Hydrothermal Liquefaction) biocrudes to produce finished liquid transportation fuel blendstocks. We report stable hydrotreating biocrude derived from sewage sludge and food waste over industrially relevant CoMo NiMo catalysts at activities. The use wet-waste-derived both in hydrotreater campaign strengthens case that a variety wet-waste feedstocks can be upgraded without significant instability time-periods. Stable...
Liquid transportation fuel blendstocks were produced by pyrolysis and catalytic upgrading of woody residue biomass. Mountain-pine-beetle-killed (MPBK) wood hog from a saw mill pyrolyzed in 1 kg/h fluidized bed reactor and, subsequently, upgraded to hydrocarbons continuous fixed hydrotreater. Upgrading was performed hydrotreatment two-stage at 170 405 °C with per liquid hourly space velocity between 0.17 0.19. The overall yields biomass similar for both feeds (24–25%), despite the differences...
Fast pyrolysis and catalytic fast (CFP) have been considered to be promising approaches for converting lignocellulosic biomass into liquid bio-oils followed by upgrading produce fuel-range hydrocarbon products. Coprocessing CFP with petroleum feedstocks leverages the existing refining infrastructure, which reduces capital expenditure overall conversion technologies fuel enables adoption of biofuels. Here, we reported coprocessing different woody vacuum gas oil (VGO) at 5–25% bio-oil blending...
Economical production of lignin-based jet fuel (LJF) can improve the sustainability sustainable aviation fuels (SAFs) as well reduce overall greenhouse gas emissions.However, challenge lies in converting technical lignin polymer from biorefinery directly to a continuous operation.In this work, we demonstrate simultaneous depolymerization and hydrodeoxygenation (SDHDO) process produce ligninbased alkali corn stover (ACSL) using engineered Ru-HY-60-MI catalyst flow reactor, for first time.The...
Background: Thermal pretreatment of biomass ranges from simple (nondestructive) drying to more severe treatments that cause devolatization, depolymerization and carbonization. These pretreatments have demonstrated promise for transforming raw into feedstock material has improved milling, handling, storage conversion properties. In this work, southern pine was pretreated at 120, 180, 230 270°C, then subjected pyrolysis tests in a continuous-feed bubbling-fluid bed system. Results: High...
Hydrothermal liquefaction (HTL) offers an attractive route to produce fuel blendstocks from wet wastes. Scaleable hydrotreating data for the conversion of HTL biocrude fuels is critical commercialization HTL. Herein, we simulate pore diffusion hydrogen into catalyst pores biocrudes and conclude that standard catalysts will be limited regarding upgrading. By changing size (crushed vs extrudate catalysts), confirm impact on overall hydrogenation rate biocrudes. When using whole pill...
