Anaerobic bioprocessing of low-rank coals

Description: The overall goal of this project is to find biological methods to remove carboxylic functionalities from low-rank coals and to assess the properties of the modified coal towards coal liquefaction. The main objectives for this quarter were: (1) continuation of microbial consortia development and maintenance, (2) crude enzyme study using best decarboxylating organisms, (3) decarboxylation of lignite, demineralized Wyodak coal and model polymers, and (4) characterization of biotreated coals.

NQR-NMR studies of higher alcohol synthesis Cu-Co catalysts

Description: During this period, we focused our attention in analyzing the magnetic nature of the extensively used trimetallic catalyst system Cu-Co-Cr for the production of higher alcohols. We believe that there could be some correspondence between the catalytic and magnetic behaviors of the transition metal catalyst systems. Both the morphology and metallic charge distribution of the particles are know to govern the catalytic as well as the magnetic properties of the system. Based on this concept, we have… more

Evaluation of gas-reburning and low NO sub x burners on a wall fired boiler

Description: The primary objective of this CCT project is to evaluate the use of Gas Reburning and Low NO{sub x} Burners (GR-LNB) for NO{sub x} emission control from a wall fired boiler. It is anticipated that, if the demonstration is successful, the GR-LNB technology could become commercialized during the 1990's and will be capable of (1) achieving significant reduction in the emissions of nitrogen oxides and sulfur dioxide (another acid rain precursor) from existing facilities to minimize environmental im… more

Enhancing the use of coals by gas reburning-sorbent injection

Description: The objective of this project is to evaluate and demonstrate a cost effective emission control technology for acid rain precursors, oxides of nitrogen (NO{sub x}) and sulfur (SO{sub x}), on two coal fired utility boilers in Illinois. The units selected are representative of pre-NSPS design practices: tangential and cyclone fired. Work on a third unit, wall fired, has been stopped because of funding limitations. The specific objectives are to demonstrate reductions of 60 percent in NO{sub x} and… more

Technology status report: Off-gas treatment technologies for chlorinated volatile organic compound air emissions

Description: The purpose of this document is to review technologies for treatment of air streams that contain chlorinated volatile organic compounds (CVOCS) and to describe a Department of Energy Office of Technology Development program that is planned to demonstrate innovative technologies for the abatement of CVOC emissions. This report describes the first phase of testing of off-gas treatment technologies. At least one more phase of testing is planned. Guidance for the preparation of this document was pr… more

Relativistic Calculations of Excitation and Ionization of Highly Charged Ions by Electron Impact. Final Technical Report

Description: Our rapid relativistic atomic structure program and relativistic distorted-wave programs for excitation and ionization of highly charged ions were further improved. The generalized Briet interaction and other QED corrections were added to the atomic structure program, and the speed of the distorted-wave excitation program was increased by over an order of magnitude over what it was when our initial large-scale relativistic calculations of excitation of Ne-like ions were made. The improved progr… more

Congress and Trade Policy Toward Japan

Description: Congressional policymaking with respect to trade with Japan is driven by strong domestic interests, appeals to broad political principles, and numerous horror stories. The $43 billion U.S. trade deficit with Japan continues to be a focus of attention, but the deficit is an issue because it reflects aggressive competition between Japanese companies and U.S. industries.
