Abstract
A coal substitute product and process for producing it from by-products formed in the production of acetylene from natural gas is disclosed. The first by-product is an aqueous slurry of soot which is mixed with the second by-product, an acetylene polymer. After mixing the material is filtered to produce a filter cake which is processed into chunks similar to coal in appearance, handling qualities and burning characteristics. Alternatively another carbonaceous tarry substance such as an asphaltenes or acryloid polymer waste can be substituted for the acetylene polymer.
