摘要

The invention discloses a modified embodiment of the process according to Patent Application P 3,311,033.6, characterised in that, in place of the mixture of urea and at least one solid ammonia derivative, urea alone or its secondary products or mixtures of these urea secondary products are now used as additives in processes for converting high-molecular carbon- and hydrogen-containing materials to lower-molecular products. The invention also comprises a further embodiment of the conversion process, characterised in that an ammonia circulation is incorporated in the conversion process. <IMAGE>
