Single-Step Syngas-to-Distillates (S2D) Synthesis via Methanol and Dimethyl Ether Intermediates: Final Report (open access)

Single-Step Syngas-to-Distillates (S2D) Synthesis via Methanol and Dimethyl Ether Intermediates: Final Report

The objective of the work was to enhance price-competitive, synthesis gas (syngas)-based production of transportation fuels that are directly compatible with the existing vehicle fleet (i.e., vehicles fueled by gasoline, diesel, jet fuel, etc.). To accomplish this, modifications to the traditional methanol-to-gasoline (MTG) process were investigated. In this study, we investigated direct conversion of syngas to distillates using methanol and dimethyl ether intermediates. For this application, a Pd/ZnO/Al2O3 (PdZnAl) catalyst previously developed for methanol steam reforming was evaluated. The PdZnAl catalyst was shown to be far superior to a conventional copper-based methanol catalyst when operated at relatively high temperatures (i.e., >300°C), which is necessary for MTG-type applications. Catalytic performance was evaluated through parametric studies. Process conditions such as temperature, pressure, gas-hour-space velocity, and syngas feed ratio (i.e., hydrogen:carbon monoxide) were investigated. PdZnAl catalyst formulation also was optimized to maximize conversion and selectivity to methanol and dimethyl ether while suppressing methane formation. Thus, a PdZn/Al2O3 catalyst optimized for methanol and dimethyl ether formation was developed through combined catalytic material and process parameter exploration. However, even after compositional optimization, a significant amount of undesirable carbon dioxide was produced (formed via the water-gas-shift reaction), and some degree of methane formation could not be …

Small Business Contracting: Updated Guidance and Reporting Needed for Consolidated Contracts (open access)

Small Business Contracting: Updated Guidance and Reporting Needed for Consolidated Contracts

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) and the General Services Administration (GSA)--which accounted for more than 80 percent of the consolidated contracts reported by all federal agencies in fiscal years 2011 and 2012--do not know the full extent to which they are awarding consolidated contracts. This is the result of contracts being misreported in the federal procurement data system. GAO reviewed 157 contracts--more than half of all DOD and GSA contracts that were reported as consolidated--and found that 34 percent of the DOD contracts and all of the GSA contracts in fact were not consolidated. GAO also identified four DOD contracts with consolidated requirements that were not reported as such."

Tribal Jurisdiction over Nonmembers: A Legal Overview (open access)

Tribal Jurisdiction over Nonmembers: A Legal Overview

The report provides an overview the Indian tribes, which are quasi-sovereign entities that enjoy all the sovereign powers that are not divested by Congress or inconsistent with the tribes' dependence on the United States. The report discusses tribal jurisdiction over nonmember Indians.
