For relining into useful fuels, most shale oils must be upgraded to reduce their nitrogen contents. Microbial cultures were established that could selectively remove heterocyclic nitrogen compounds from raw shale oil. Each culture was highly specific with regard to the compounds it could attack.

Basic nitrogen compounds occurring in shale oil can be selectively adsorbed by spent oil shale ash that has first been treated with either a mineral acid, e.g. HCI, or a Lewis acid, e.g. CuCl,. For Rundle shale oil a reduction in the basic nitrogen level from 0.55 wt y0 to less than 0.05 wt %, and t
