ABSORBER OF GASES AND ODOR NUISANCES (VERSIONS) AND ORGANIC MINERAL FERTILISERS Russian patent published in 2013 - IPC B01J20/02 B01D53/34 B01D53/52 C05F15/00 

FIELD: process engineering.

SUBSTANCE: invention relates to compositions of multicomponent absorbers of gases and odor nuisances based on wood biomass, namely, needles of pine and other conifers. It can be used for sanitary purification of off-gases (hydrogen sulphides, methane an the like) at clearing equipment and deodorisation of toilets at garden-plots and rural sites, deodorisation of whatever excrements, manure, etc. Proposed absorber comprises softwood processing wastes and pine-needle oil at the ratio of 99.99:0.01-99.00:1.00. Besides it may contain some other wood wastes, that it, sawdust and/or bark, and/or peat at the following ratio of components in wt % softwood wastes - 40.00-60.00, pine-needle oil - 0.01-1.00, sawdust and/or bark, and/or peat making the rest - up to 100%.

EFFECT: expanded range of absorbers, better environmental conditions.
