Heterogeneous Catalyst Engineer

The thermal activation and calcination stage represents the most critical thermodynamic process in heterogeneous catalyst manufacturing. The engineer models and operates rotary calcination kilns, tunnel hearths, and fluidized bed calciners operating at temperatures between four hundred and one thousand degrees Celsius. Careful ramp rates, sweep gas flows, and steam partial pressures prevent metal sintering, pore collapse, or unwanted phase transitions. Conforming to standards established by the International Union of Pure and Applied Chemistry IUPAC and the American Institute of Chemical Engineers AIChE, the engineer evaluates specific surface areas, pore size distributions, and acid base site distributions using nitrogen physisorption and temperature programmed reduction methods.

While automated robotic synthesis platforms and quantum chemical DFT calculations accelerate the initial screening of catalytic formulations, pilot scale manufacturing introduces non linear hydrothermal, mass transfer, and mechanical challenges. Extrusion rheology, tablet crushing strength, attrition resistance during turbulent gas fluidization, and long term hydrothermal stability under real industrial feedstocks containing sulfur or heavy metal poisons demand experienced human chemical engineering oversight directly on the manufacturing plant floor.

The day begins at seven in the morning in the catalyst preparation pilot facility, where a five hundred kilogram batch of nickel impregnated alumina catalyst has completed overnight rotary calcination. Wearing a respirator and protective lab coat, the engineer inspects the product discharge hopper, observing the uniform slate gray color indicating homogeneous metal precursor decomposition without localized hot spots. After verifying the kiln temperature log recorded a stable plateau at five hundred and fifty degrees Celsius with a nitrogen sweep of ten normal cubic meters per hour, they collect composite grab samples for immediate quality control. In the characterization lab,

the engineer prepares samples for rapid BET surface area testing, degasifying the material at three hundred degrees Celsius before initiating multipoint nitrogen adsorption. The instrument outputs a specific surface area of one hundred and eighty five square meters per gram with a narrow mesopore distribution centered at eight nanometers, perfectly within customer specifications for gas reforming. Concurrently, they set up a temperature programmed reduction run to confirm that the nickel oxide crystallites reduce completely to active metallic nickel at four hundred and twenty degrees Celsius without sintering. During the afternoon,.

A Heterogeneous Catalyst Synthesis and Calcination Engineer researches, formulates, scales up, and manufactures solid industrial catalysts utilized in petrochemical cracking, green hydrogen production, carbon dioxide valorization, and environmental emission control. Working across specialized catalyst development laboratories and industrial calcination production facilities, the engineer synthesizes porous transition metal and precious metal formulations on high surface area alumina, silica, titania, and zeolite supports. The engineer controls precipitation pH, hydrothermal aging times, wash salt conductivities, and incipient wetness impregnation volumes to disperse active metal crystallites with nanometer precision across porous substrate architectures.

Core responsibilities include formulate and synthesize solid heterogeneous catalysts utilizing incipient wetness impregnation, co precipitation, and hydrothermal methods., operational coordination, and ensuring strict adherence to Kenyan statutory frameworks and quality standards.

Key organizations hiring for this role include Kenya Medical Research Institute KEMRI, Dawa Life Sciences, Cosmos Pharmaceuticals Limited, Bio Foods Kenya, alongside expanding opportunities in Nairobi, Mombasa, Kisumu, and regional infrastructure projects.
