Number: 585/240
Name: Chemistry of hydrocarbon compounds > Production of hydrocarbon mixture from refuse or vegetation
Description: Subject matter in which the starting (feed) material of the process is plant material in a chemically unaltered form or is a material which ordinarily would be discarded as of no value, e.g., municipal waste, refinery sludge, etc., is treated to recover therefrom a mixture of hydrocarbons, e.g., a fuel "oil" fraction, etc.
