Pilot-scale entrained flow gasification experiments were carried out at the 3 MWth LTU Green Fuels black liquor (BLG) plant, using ∼140 tons of Kraft (BL) with a dry solids content ∼72.5%. Comprehensive mass and energy balances performed to quantify process performance under varying pressure, load, oxygen/fuel ratio. Carbon conversion efficiency BLG was 98.3%–99.2% did not vary systematically in response changes. The unconverted carbon is almost exclusively present as dissolved organic green...
Mitigating the climate impact from aviation remains one of tougher challenges in adapting society to fulfill stated targets. Long-range cannot be electrified for foreseeable future and effects combusting fuel at high altitude increase compared emissions green-house gasses only, which further limits range sustainable alternatives. We investigate seven different pathways producing biofuels coupled with either bio-energy carbon capture storage (BECCS), or utilization (BECCU). Both options allow...
Drop-in biofuels from forest by-products such as black liquor can help deliver deep reductions in transport greenhouse gas emissions by replacing fossil fuels our vehicle fleet. Black is produced at pulp mills that increase their pulping capacity upgrading some of it to drop-in but this not well-studied. We evaluate the techno-economic and performance five biofuel pathways based on BL lignin separation with hydrotreatment or gasification catalytic synthesis. also assess how integrated...
As fossil-reliant industries turn to sustainable biomass for energy and material supply, the competition biogenic carbon is expected intensify. Using process level balance models, this paper shows how capture of residual CO 2 in conjunction with either permanent storage (CCS) or biofuel production (CCU) benefits fourteen largely residue-based pathways. With a few noteworthy exceptions, most pathways have low utilization efficiencies (30–40%) without CCS/U. CCS can double these numbers...
The main goal of this work is to investigate if thermodynamic equilibrium calculations can be useful for understanding and predicting process performance product composition entrained flow gasification spent pulping liquors, such as black liquor. Model sensitivity input data studied model results are compared published pilot plant data. high temperature the catalytic activity feedstock alkali make a better predictor than many other types biomass technologies. Thermodynamic predict flows...
Uncertain and unstable policy support has often been claimed to be a major cause of the slower than expected deployment technologies for production advanced biofuels. We investigate economic rationale this claim by applying real options framework incorporating uncertainties regarding energy prices, investment costs, prevalence support, in terms an per produced unit biofuel depending on greenhouse gas (GHG) mitigation potential. Six industrially relevant forest-based drop-in biofuels were...
