                 Fisher and Bergius processes are described.  The former embodies non-catalytic polymerization of hydrocarbons, catalytic polymerization of olefins, dechlorination of chlorinated hydrocarbons and condensation of these with olefins, and condensation of chlorinated products with aromatic hydrocarbons.  It is shown that ethylene and paraffins, byproducts of the Fischer process, constitute an important source for the production of lubricants.
