Improving the fluidized catalytic cracking (FCC) profit potential of heavy feeds. SMR technology features. The need to process heavy feeds in FCC units continues to grow. Albemarle’s innovative SMR catalyst technology addresses the three fundamentals of heavy feed cracking: coke and dry-gas selectivity; metals tolerance; and bottoms upgrading. Through its three innovative developments, SMR technology enables refiners to operate at higher metal levels or at higher severities while upgrading more heavy feed or bottoms to valuable products.

First, SMR catalyst technology greatly reduces the vanadium intra- and interparticle mobility, thereby protecting the zeolite from destruction by vanadium. And, as its matrix is also less exposed to vanadium attack, the catalyst retains its functionality longer, which enables it to do the high-level-performance job required when converting heavy feed molecules.

Second, in SMR catalyst technology, the catalyst can encapsulate nickel, which reduces metals coke and hydrogen. This exclusive development leads the industry, as it offers outstanding nickel encapsulation power with minimal dehydrogenation reactions. Third, SMR catalyst technology features a stronger and more effective zeolite contribution to the cracking reaction. In addition to higher activity, the ratio of catalytic cracking to thermal cracking is enhanced, which reduces the kinetic coke and dry gas make.

Our CORAL catalyst, which was originally designed for heavy feed applications, was one of our first products to benefit from SMR catalyst technology. CORAL SMR, which is exclusively available from Albemarle, encompasses these three technology developments to enable refiners to make more money on the higher value products leaving their plants.
