The Co-Optimization of Fuels and Engines (Co-Optima) initiative from the US Department Energy aims to co-develop fuels engines in an effort maximize energy efficiency utilization renewable fuels. Many these fuel options have chemistries that are different those petroleum-derived Because practical market need meet specific fuel-property requirements, a chemistry-agnostic approach assessing potential benefits candidate was developed using Central Fuel Property Hypothesis (CFPH). CFPH states...
Metal ions exchanged on zeolites represent a unique bridge between heterogeneous solid materials and homogeneous inorganic chemistry. The complexing of metal with H2O or NO, is particular relevance for number reactions, including the ubiquitous presence both gases in pollution remediation technologies. Here, we interrogate molecular structure Pd cations SSZ-13 their interaction NO using experimental computational analyses. Density functional theory (DFT) spectroscopic characterization...
The development and optimization of catalysts catalytic processes requires knowledge reaction kinetics mechanisms. In traditional catalyst kinetic characterization, the gas composition is known at inlet, exit flow measured to determine changes in concentration. As such, progression chemistry within not known. Technological advances electromagnetic physical probes have made visualizing evolution samples a reality, as part methodology commonly spatial resolution. Herein, we discuss evaluate...
A detailed thermodynamic analysis of thermochemical recuperation (TCR) applied to an idealized internal combustion engine with single-stage work extraction is presented. Results for several different fuels are included. For a stoichiometric mixture methanol and air, TCR can increase the estimated ideal second law efficiency by about 3% constant pressure reforming over 5% volume reforming. ethanol isooctane, increases 9 11%, respectively. The improvements from result primarily higher...
Fuel injection into the negative valve overlap (NVO) period is a common method for controlling combustion phasing in homogeneous charge compression ignition (HCCI) and other forms of advanced combustion. When fuel injected O2-deficient NVO conditions, portion can be converted to products containing significant levels H2 CO. Additionally, short chain hydrocarbons are produced by means thermal cracking, water-gas shift, partial oxidation reactions. The present study experimentally investigates...
For commercialization, alcohol-based net zero carbon fuels in diesel-driven internal combustion (IC) engines need to meet emissions standards set by the U.S. Environmental Protection Agency (EPA). A series of aged commercial oxidation catalysts, Pt diesel catalyst (DOC), Pd+Pt DOC, and (Pt OC) were studied using an automated flow reactor situ DRIFTS techniques investigate mutual inhibition effects between CO alcohol during co-oxidation. Sequential introduction experiments conducted on all...
