Coal and black liquor can produce energy from papermaking
Date:8/20/2007

efficiency of using black liquor as the feedstock for manufacturing synthesis gas and then DME, and realized that they needed the economy of scale for the process to be really efficient and economical. The capacity of paper mills for fuel production could be expanded by co-processing coal with the black liquor.

A potential approach is to combine the black liquor with a coal slurry and process that. Paper mill processes then treated this mixture with steam and only a little oxygen to convert the organic compounds into hydrogen and carbon monoxide. These products traditionally have then been used in the Fischer Tropsch method to produce a mixed petroleum-like product that must be further refined before use. The students suggest the DME process because it is less energy intensive and produces a targeted product, DME, and while DME is a specialty fuel, its use is increasing worldwide.

Looking at a comparison of energy efficiency, the students found that gasoline and diesel fuel have the lowest energy cost to produce, but DME is not that far away in efficiency. DME is also much cleaner burning than either gasoline or diesel.

Converting black liquor and coal into DME also releases less carbon as carbon dioxide into the atmosphere than if coal alone was used to produce the fuel. Some of the carbon from these sources remains sequestered in solid form and do not add to global warming.

"Another reason we may want to co-process coal with black liquor is to stretch our coal reserve," says Boehman. "We have always known that coal reserves are finite, but now it appears we will not be able to mine all the available coal there is due to environmental concerns."
