Low Btu Producer Gas -- A Fuel Of The Past And A Fuel Of The Future, Lee Carter Oct 1978

Low Btu Producer Gas -- A Fuel Of The Past And A Fuel Of The Future, Lee Carter

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

A prime purpose of this paper is to give conscious emphasis to an important type of coal gasification, one that does not demand hundreds of millions of dollars to launch an experimental program but instead is essentially ready to use after a reasonable and straightforward engineering check-out of the local coal sources and the prospective gas demand.

That type of coal gasification results in low Btu producer gas. This paper deals with its history, its technology and its economics. In the light of that information, the future of low Btu producer gas in America then is assessed.

Comparison Of Stirred And Immobilized Cell Reactors For Ethanol Production, Oliver C. Sitton, J. L. Gaddy

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Biomass can be converted to sugars by hydrolysis with enzymes or mineral acids. These sugars can be converted into a number of chemical intermediates in biological reactors. Biological reactions are generally slow and selection of the most efficient reactor is important in these applications.

Immobilized cell reactors allow high cell densities and high throughput by attaching microorganisms to a fixed support. This paper compares the rate of production of ethanol from glucose by Saccharomyces Cerevisiae in a packed column and a stirred reactor.

Continuous stirred reactor studies showed a washout rate of .27 hr-1. The optimum rate of …

Burning Wood As A Supplement To Solid Waste, Andrew R. Banta, William P. Smith Oct 1978

Burning Wood As A Supplement To Solid Waste, Andrew R. Banta, William P. Smith

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The University of Kansas at Lawrence uses natural gas and oil to generate steam for heating and other campus needs. The projected price increase of these fuels has led to a study of burning solid waste and wood. This study discusses the technical and economic considerations of burning wood. Topics included are sources and availability, collection and transportation, preparation and burning, and environmental effects. It is concluded that sufficient wood is available; truck transport is the only feasible option; drying some wood is desirable; and that the burning can be done separately or directly with the solid waste.

An Analysis Of Solar Heating Costs In Arkansas Broiler Houses, Ralph Gunderson, J. Martin Redfern Oct 1978

An Analysis Of Solar Heating Costs In Arkansas Broiler Houses, Ralph Gunderson, J. Martin Redfern

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

This study is based on the computer simulation model of a solar heated broiler house in four locations in Arkansas. This simulation model estimated the annual energy savings in each broiler house due to the installation of a solar heating system. This paper uses present value analysis to estimate the life cycle costs of heating conventional and solar heated broiler houses in the state of Arkansas. From these calculations, the number of years required to achieve a break-even cost of heating is estimated.
