Gas is yielded and may be subsequently withdrawn from a subsurface formation of hydrocarbon material by passing a controlled amount of current from a direct source through the formation. The gas produced by this process has a high quality Btu content and is produced, in situ, under relatively moderate operating conditions. Furthermore, the gas yielded by this method has a reduced amount of hydroge...

The invention relates to a method for obtaining protein-containing animal feed from organic substances dissolved and/or suspended in water, where the substances are biologically processed in at least two series-connected stages (I, II) each having an activating tank (5, 7) and a settling tank (6, 8). In the first stage (I) a larger percentage of bacteria than protozoea prevails. The sludge is drai...
