Publication number: 20130160683Abstract: In the processes for treating municipal sewage and storm water containing biosolids to discharge standards, biosolids, even after dewatering, contain typically about 80% water bound in the dead cells of the biosolids, which gives biosolids a negative heating value. It can be incinerated only at the expense of purchased fuel. Biosolids are heated to a temperature at which their cell structure is destroyed and, preferably, at which carbon dioxide is split off to lower the oxygen content of the biosolids. The resulting char is not hydrophilic, and it can be efficiently dewatered and/or dried and is a viable renewable fuel. This renewable fuel can be supplemented by also charging conventional biomass (yard and crop waste, etc.) in the same or in parallel facilities. Similarly, non-renewable hydrophilic fuels can be so processed in conjunction with the processing of biosolids to further augment the energy supply.Type: ApplicationFiled: February 22, 2013Publication date: June 27, 2013Applicant: SGC ADVISORS, LLCInventor: SGC ADVISORS, LLC

Method for the removal of inorganic compounds of biomass from agricultural, forest and urban sources
Patent number: 8471080Abstract: Described is a methodology aiming to the removal of harmful ash constituents from the ash of biomass, such as alkali metals, chlorine and sulfur, prior to is thermochemical conversion, in order to minimize/eliminate the ash-related corrosion, deposition and agglomeration problems, as well as the emissions of alkali metals, chlorine and sulfur. This removal is achieved by a combined pre-treatment which includes prepyrolysis of biomass at temperatures varying in the range of 200-300° C. and for a period of 5 min up to 2 h, followed by the leaching of the biomass materials using water with a solid/water mass ratio varying from 33 g/L up to 300 g/L with water temperature varying from 13° up to 55° C. and residence time varying from 5 min up to 24 h.Type: GrantFiled: June 27, 2008Date of Patent: June 25, 2013Assignee: Thesmorefinery Technologies LLCInventor: Emmanouil Koukios -
Patent number: 8471081Abstract: A process has been developed for producing diesel fuel from crude tall oil. The process involves treating a renewable feedstock by hydrogenating and deoxygenating to provide a diesel boiling range fuel hydrocarbon product. If desired, the hydrocarbon product can be isomerized to improve cold flow properties. A portion of the hydrocarbon product is recycled to the treatment zone to increase the hydrogen solubility of the reaction mixture.Type: GrantFiled: February 5, 2010Date of Patent: June 25, 2013Assignee: UOP LLCInventor: Michael J.
