<p>The present invention addresses the processing of waste and low-value productsto produce useful materials in reliable purities and compositions, at acceptablecost, and with high energy efficiency. In particular, the invention comprisesa multi-stage process that converts various feedstocks (100) such as offal,animal manures, municipal sewage sludge, that otherwise have little commercialvalue, to useful materials including gas (146), oil (144), specialty chemicals(143), and carbon solids (142). The process subjects the feedstock (100) to heatand pressure in a reducing environment accomplished by controlled additionof sulfur and sodium, separates out (130) various components, then further appliesheat and pressure to one or more of those components. The invention further comprisesan apparatus for performing a multi-stage process of converting waste productsinto useful materials, and at least one oil product that arises from the process.</p> |
