The Digest’s 2024 Multi-Slide Guide to Jen-Zero technology

This is a presentation by Dr. Jayant Khambekar of Jenike & Johanson, a technology company specializing in bulk solids flow. It highlights the challenges of feeding high-pressure reactors in the advanced biofuels industry. Specifically, the presentation discusses the difficulties of using difficult-to-handle feedstocks like agricultural residue, forest residue, and municipal solid waste, which are crucial for achieving net zero emissions targets. Existing technologies like conventional lock hoppers and plug screw feeders struggle with these materials, leading to problems like arching, ratholing, pressure blow-back, and excessive compression/jamming. Jenike & Johanson proposes a solution with their patent-pending Jen-ZeroTM technology, which aims to achieve reliable feeding and reduce operating expenses (OPEX) by eliminating the need for pre-treatment methods such as pelletization and size reduction.
