| 摘要 | A method for separating hydrocarbon content from a hydrocarbon contaminated matrix. The method includes controlling water content of a feed material having the hydrocarbon contaminated matrix; continuously conveying the feed material into a treatment cavity; exposing the feed material in a treatment area of the treatment cavity to microwave radiation arranged to cause rapid heating of at least a portion of the water content to form steam, wherein the rapid steam formation results in thermal desorption of at least a portion of the hydrocarbon content from the matrix; and continuously removing the treated matrix from the treatment cavity. | ||

| 主权项 | 1. A method for separating a hydrocarbon content from a hydrocarbon contaminated matrix, comprising the steps of: controlling water content in a feed material comprising the hydrocarbon contaminated matrix wherein the water content of the feed material is controlled by blending a material of known water content with the hydrocarbon contaminated matrix; continuously conveying the feed material into a treatment cavity; exposing the feed material in a treatment area of the treatment cavity to microwave radiation arranged to cause rapid heating of at least a portion of the water content to form steam, wherein the rapid steam formation results in thermal desorption of at least a portion of the hydrocarbon content from the matrix; and continuously removing the treated matrix from the treatment cavity; wherein the microwave radiation has a frequency in the range 10MHz to 10GHz. | ||
