Title: Bruce E. Dale: Innovator in Cellulose Reactivity

Introduction

Bruce E. Dale is a prominent inventor based in Fort Collins, Colorado. He has made significant contributions to the field of cellulose reactivity, holding a total of 3 patents. His innovative approaches have the potential to enhance the digestibility and reactivity of cellulose-containing materials, particularly in agricultural applications.

Latest Patents

One of his latest patents is a process for increasing the reactivity of cellulose-containing materials. This process involves contacting the material, in a pressure vessel, with a volatile liquid swelling agent such as ammonia. The agent has a vapor pressure greater than atmospheric pressure at ambient temperatures. The contact is maintained for a sufficient time for the agent to swell the cellulose of the material. The pressure is then rapidly reduced to atmospheric pressure, causing the agent to boil and explode the material. This rapid pressure reduction also results in some freezing of the cellulose. The swelling agent is subsequently separated from the cellulose-containing material and recovered for recycling.

Another notable patent is a method for increasing the reactivity and digestibility of cellulose. In this method, cellulose-containing materials are treated to enhance their chemical and biological reactivity. Similar to the previous process, the cellulose is contacted with a volatile liquid swelling agent in a pressure vessel. The agent swells the cellulose fibers, and the pressure is rapidly reduced to allow the agent to boil and explode the cellulose fiber structure. The agent is then separated and recovered for recycling.
