Use of high-resolution thermogravimetric analysis (HRTG) technique in spent FCC catalyst/Portland cement pastes
(Springer, 2015-06-01)
Thermogravimetric analysis is one of the most common instrumental techniques used for the characterization of pastes, mortars and concretes based on both calcium hydroxide and Portland cement. Important information about ...
Spent FCC catalyst for preparing alkali-activated binders: An opportunity for a high-degree valorizatio
(2014-01-01)
Spent FCC catalyst is a waste from the petrochemical industry which has excellent pozzolanic properties, containing more than 90% silica and alumina. Its similarity to metakaolin creates interesting prospects for its use ...
Alkali activated materials based on fluid catalytic cracking catalyst residue (FCC): Influence of SiO2/Na2O and H 2O/FCC ratio on mechanical strength and microstructure
(2013-03-29)
Reuse of industrial and agricultural wastes as supplementary cementitious materials (SCMs) in concrete and mortar productions contribute to sustainable development. In this context, fluid catalytic cracking catalyst residue ...

Using spent fluid catalytic cracking (fcc) catalyst as pozzolanic addition — a review
(Universidad Nacional de Colombia - Facultad de Ingeniería, 2010)
Spent fluid catalytic cracking (FCC) catalyst is an oil industry by product from fluidised-bed catalytic cracking units. This residue is mainly formed by an active component (faujasite type zeolite Y) in an amorphous ...
Study of a Brazilian spent catalyst as cement aggregate by thermal and mechanical analysis
(2008-04-01)
Fluidized catalytic cracking units of refineries normally use zeolite catalysts to treat heavy oil fractions. This catalyst is regenerated continuously, but due to the reduction of its activity during the process, it is ...
