Recovery of sulphur dioxide from gas mixtures
It should, by now, go without our saying so that elemental, molecular Hydrogen, H2, is darned-handy stuff to have a little bit of.
As seen in:
WVU Hydrogenates Coal Tar | Research & Development; concerning: "Hydrogenation of Naphthalene and Coal Tar Distillate; West Virginia University; 2009; Abstract: The hydrogenation of naphthalene and coal-tar distillates ... in the presence of hydrogen ... for the hydrogenated product, tetralin ... (which can be used to produce) liquid fuel from solid coal";

We've previously cited the named inventor of the United States Patent for Coal conversion technology we enclose herein. He is one of the authors identified in our earlier report of:
New York City (!!!) Improves Coal Liquefaction | Research & Development; which concerned: "Improvement of Coal Direct Liquefaction by Steam Pretreatment; O. Ivanenko, R.A. Graff, et. al., City College of New York".
We've eschewed the use of exclamation points in the headline of this dispatch.

As we've documented, and tried to explain, in many of our previous reports, the key to converting Coal and Carbon Dioxide into - more versatile and more desired - Hydrocarbons lies in combining the Carbon content of CO2 and Coal in some way with Hydrogen.
Hydrogen is a common element, of course, as the chemical formula for plain old Water, i.e., "H2O", attests.

We enclose in this dispatch report of an intriguing use for Sulfur Dioxide, SO2, which can be scrubbed, in greater or lesser quantities, depending on the grade of Coal used, from the exhaust gases of some Coal-fired power plants.
Maybe we don't like to talk about the supposed pollutants arising from our productive and essential uses of Coal, but, when, as in the case of CO2, and the technologies related to it's productive recycling, as seen in:

We'll be bouncing around a bit in this dispatch, and are including a number of links and excerpts. And, we'll hopefully have it organized in such a way that it won't be too confusing.
First, we've reported and documented many times that Coal can be gasified with Steam, i.e., H2O, and, be made thereby to yield a blend of Carbon Monoxide and elemental, molecular Hydrogen, H2; a combination of gases commonly known as "synthesis gas", or "syngas", which can be subsequently reacted together, through the action of a catalyst, and be made thereby to form a variety of gaseous and liquid hydrocarbons.
