ABSTRACT:
Low heating value liquid hydrocarbonaceous and/or solid carbonaceous hazardous waste materials from the production, refining and marketing of petroleum products are destroyed without contaminating the environment while simultaneously gaseous mixtures comprising H.sub.2 +CO i.e. synthesis gas, reducing gas, or fuel gas are produced. From about 0.3 to 2.0 wt. % of an anionic surface active dispersant and water (if needed) are mixed with the hazardous waste material to produce a first aqueous mixture. A comminuted solid carbonaceous fuel i.e. coal, petroleum coke is mixed with water and from about 0.02 to 1.00 wt. % of the dispersant to produce a second stable pumpable aqueous slurry. The first and second aqueous slurries are mixed together to produce a stable pumpable final blend aqueous slurry which is reacted in a partial oxidation gas generator as the feedstock. It was unexpectedly found that to achieve slurries with satisfactory rheological properties from mixtures of hazardous waste material and coal or coke slurries, it was necessary to add the dispersant to the coal/coke slurry as well as to the slurry of hazardous waste material before combining the two aqueous mixtures together.
