MATRIC MATTERS: Fluidization Reaction

A customer had studied the fixed-bed reaction of a solid particulate material with a gas under pressure at elevated temperature but wanted to study the reaction in a fluidized bed. MATRIC assembled a lab-scale reaction system that fluidized the solid reactant and provided precise control of temperature and gas flow rates. The reaction was [...]

MATRIC MATTERS: Continuous Flow Reaction System

A reactor was designed for a continuous flow of gas and liquid that needed to be thoroughly mixed on entering the reactor at pressures up to 100 atm. The mixture was highly corrosive and flammable, requiring special materials of construction and rigorous operating procedures. After identifying and addressing several operational issues, the concept was successfully [...]

MATRIC MATTERS: Heterogeneous Catalyst Dual Reactor System

A reaction system consisting of two fixed-bed catalyst reactors in series was design and constructed for use in trickle-bed operation. The reactors were each about 1 meter long and 5 cm in diameter, with internal multipoint thermocouples. The reactors were valved to allow their individual operation as needed. This unit allowed operation of the two [...]


SOUTH CHARLESTON, W.Va.; Sept. 19, 2022 – Mid-Atlantic Technology, Research & Innovation Center, Inc. (MATRIC) today announced that Parvez H. Wadia, D.Sc., vice president, strategic initiatives, has received the national Earle B. Barnes Award for Leadership in Chemical Research Management from the American Chemical Society (ACS). Only one individual is recognized with this award [...]

MATRIC MATTERS: Analytical Chemistry

A company in the service industry relied on several analytical providers to determine the detailed composition of complex product streams. Samples were being sent to various locations for analysis, and slow turnaround times meant that the results of process changes could not be tracked in a timely manner. The result was lost time and [...]

MATRIC Deep Dives into Ethylene Oxide for Kirk-Othmer Encyclopedia of Chemical Technology

MATRIC was recently featured in the Kirk-Othmer Encyclopedia of Chemical Technology about Ethylene Oxide. The Kirk-Othmer Encyclopedia of Chemical Technology is a leading publisher of scholarly articles on key chemicals—including their properties, manufacturing, and uses, all written by prominent scholars from industry, academia, and research institutions. It also focuses on industrial processes and unit operations [...]

MATRIC MATTERS: Crystallization

MATRIC undertook a project to assist a customer who wanted to improve the recovery and purity of a product obtained by solution phase crystallization. The situation was complicated by the presence of two crystalline polymorphs that differed significantly in their ease of separation from the mother liquor. MATRIC staff carried out a series of batch [...]


SOUTH CHARLESTON, W.Va.; January 31, 2022 – Mid-Atlantic Technology, Research & Innovation Center (MATRIC) today announced that its long-term partner, Iowa Corn Promotion Board (ICPB), recently announced that it has entered into an Asset Purchase Agreement with another company for it to acquire ICPB’s patents, technology and rights for the process technology to produce monoethylene [...]

MATRIC MATTERS: Fixed Bed Catalyst Testing

Catalysts were being developed for a liquid phase reaction of interest to a customer. MATRIC assembled three parallel fixed bed reaction systems with continuous feeds of the reactants. The units were operated around the clock with periodic mass balance and composition analyses over a period of more than 12 months. The effects of different feed [...]

MATRIC MATTERS: Co-Polymer Sample Production

A customer was interested in the properties of a family of co-polymers produced from ethylene and a selection of functionalized co-monomers. MATRIC set up a small 300 mL reactor to perform the polymerization under high ethylene pressure and prepared several small samples to prove the concept and evaluate the effects of reaction conditions. The process [...]
