Benefits of technology

The invention is a way to make a high-calorific value combustible product from organic and biomass materials, like waste wood, in a short time. The process can use raw or moist feedstock materials without needing to be dried first. This can help dispose of waste wood fines, which is currently a big issue.

Problems solved by technology

Longer reaction times may be employed but result in a significant reduction in particle size of the end product, which can make filtration difficult.

Embodiment Construction

[0028]The feedstock materials contain a large amount of organic material which can be converted into a useful combustible product. The process of the present invention is concerned with a process of converting the feedstock, such as sewage sludge and wood, into a combustible product. The combustible product is typically in the form of a coal-like material and it may optionally be further processed to provide a combustible product in liquid form.

[0029]Due to the difference in moisture content of organic and biomass feedstock the process prepares the materials in different methods to achieve the optimal feedstock conditions required.

[0030]FIG. 1 shows flow charts of the processes 20 for the preparation of feedstock.

[0031]Organic feedstock 20 is fed into the feed hopper 21 via mechanical loading machine and onto a conveyor belt. It passes a metal separation stage 22 to remove any unwanted metallic objects via an over conveyor magnet and or drum magnet. The material is then deposited in...

Abstract

A process for producing combustible product from an organic or biomass feedstock, the process comprising: mixing the feedstock with an alkaline material to give an alkaline aqueous mixture; heating the mixture by ohmic heating to a temperature in the range of about 280° C. to about 320° C. and reacting the mixture under subcritical conditions at the said temperature range and a pressure of about 6.6 to about 11.6 MPa (65 bar gauge to about 115 bar gauge); and removing at least some of the water to leave a combustible product, which may be used to form an aqueous slurry, suspension or emulsion and combusted in a suitable engine.

Description

BACKGROUNDa. Field of the Invention[0001]The invention relates to a process for producing a combustible product from an organic or biomass feedstock, and to methods of using the product. Other aspects of the invention provide a liquid suspension or emulsion derived from the combustible product and suitable for use as a liquid fuel.b. Related Art[0002]There have been many attempts at producing fuels and biogas from various forms of biomass and organic materials. There has been investigation into advanced conversion, using pyrolysis and gasification, of organic, plant and human waste to produce fuels and biogas. The biomass and organic feedstock is subjected to advanced conversion at temperatures of, for example, from 250 to 800° C.[0003]Other processes include the generation of gaseous fuels, comprising methane from various forms of biomass organic feedstock using techniques such as anaerobic digestion.[0004]One form of organic feedstock is sewage sludge in digested or raw form from ...
