NOVELTY - Self powered apparatus (10), comprises: a feedstock tank (20); a preparation tank (30) for preheating of the feedstock to save energy; a first hot air heat exchanger (40); a stack (50); a second hot air heat exchanger; a cracking kettle; an oxidizer for burning light ends; a distillation tower to process gases from the cracking kettle; a condenser; a filter and chiller unit to remove particulates and sulfur; storage tanks to hold fuels and residuals; and a closed loop control computer programmed with sophisticated software to monitor, configure, and automate operation of the apparatus.    USE - The self powered apparatus is useful for conversion of disposable hydrocarbons into diesel and heating oil fuels and for conversion of biomass into biodiesel fuel, where the disposable hydrocarbons comprise refinery residuum/slop oil, tank bottoms, bilge water, oil spills, oil waste collector's blend, waste motor oil, grease, paint thinner, gasoline or jet fuel, and the biomass is comprised of tallow, algae, chicken fat, cooking oil and grease, palm oil, soy bean oil or is liquefied if not already liquid (all claimed).    ADVANTAGE - The self powered apparatus: provides biodiesel which is biodegradable and non-toxic; and provides economic incentives for the shipping companies to cease their dumping of bilge water at sea. The method produces commercially saleable fuels in an environmentally clean and pollution free manner using only the byproducts.    DETAILED DESCRIPTION - Self powered apparatus (10), comprises: a feedstock tank (20); a preparation tank (30) for preheating of the feedstock to save energy; a first hot air heat exchanger (40) to separate out from the feedstock light ends and water as steam; a stack (50) to vent the steam to the atmosphere; a second hot air heat exchanger to raise the temperature to that necessary for processing the feedstock less water and light ends; a cracking kettle in which the feedstock less water and light ends is processed; an oxidizer for burning the light ends, and optionally one of inferior product and finished fuel oil if any, to generate heat for the first and second hot air heat exchangers, and which, after start up with an outside heat source, provides sufficient heat to power the entire apparatus and process continuously; a distillation tower to process gases from the cracking kettle, where the distillation tower separating gaseous diesel fuel from fuel oil if any; a condenser to convert gaseous diesel fuel to liquid diesel fuel; a filter and chiller unit to remove particulates and sulfur and lower product temperatures; storage tanks to hold diesel, fuel oil, if any, and residuals removed from a bottom of the distillation tower, and at least some of which are circulated from the residuals storage tank back to the preparation tank to warm the feed stock from retained heat in the residuals, which residuals are then recirculated back to the residuals storage tank; and a closed loop control computer programmed with sophisticated software to monitor, configure, and automate operation of the apparatus. An INDEPENDENT CLAIM is also included for a self powered method of conversion of disposable hydrocarbons into diesel and heating oil fuels and for conversion of biomass into biodiesel fuel in a three stage heating process comprising: drawing feedstock from a feedstock tank into a preparation tank; preheating the feedstock in the preparation tank to save energy using retained heat in the residuals and heating oil to warm the feed stock to 125 degrees F by circulating the residuals and heating oil through piping in the preparation tank as first and second liquid to liquid heat exchangers; heating the feedstock in a first hot air heat exchanger to drive off light ends and water as steam, which is vented by a stack to the atmosphere; heating the feedstock in a second hot air heat exchanger to processing temperature; processing the feedstock in a cracking kettle to produce gaseous diesel and heating oil or biodiesel; oxidizing and incinerating light ends, and if necessary to obtain sufficient heat inferior product and heating oil or biodiesel to generate heat for the process including especially the first and second hot air heat exchangers; separating the gaseous diesel and heating oil exiting the cracking kettle in a distillation tower; converting gaseous diesel fuel to liquid diesel fuel in a condenser; removing particulates and sulfur and lower product temperatures in a filter and chiller unit; storing diesel and fuel oil or biodiesel, and residuals removed from a bottom of the distillation tower in storage tanks; and monitoring, configuring, and automating operation of the method using a closed loop control computer programmed with sophisticated software.
