The computer technologies of machine learning and multiobjective optimization were introduced to develop the catalyst for fluid catalytic cracking (FCC). Response surface methodology was applied a training set consisting 1000 data points with varied compositions which consist variety catalysts compositions, feedstock properties, pseudo-equilibrium conditions, performance test conditions as inpu...

Use of lime as construction material is limited mainly by low initial strength. These properties can be improved adding pozzolanic materials, but the evolution reaction usually needs older ages than 7 days. Alkali-activated or geopolymers, are good-performance materials that produced with residual waste. The combination traditional and new lead to uses mortars. This paper studies a lime/pozzola...

Nowadays, the optimal control of a heat integrated industrial plant becomes one of the most important research areas in the chemical industry. There are at least two main reasons why this topic is interesting: first, the reduction of production costs applying the heat integration techniques and second, process optimization through advanced control alternatives, when taking into account the impr...

Qualitative and quantitative description are key to solving the problem of heavy metal contamination on fluid catalytic cracking (FCC) catalysts. The loading efficiencies for different metals were compared two lab simulation methods Multi-Cyclic Deactivation (MCD) Advanced Catalyst Evaluation (ACE), microcatalytic performance metal-contaminated catalysts was evaluated using an ACE Model C devic...

The guaiacol adsorption capacity of several Y zeolites with different physicochemical properties was tested by performing breakthrough experiments, in order to investigate the on Fluid Catalytic Cracking catalysts during bio-oils/FCC feedstocks co-processing. X-Ray diffraction, nitrogen sorption measurements and pyridine followed Infrared Spectroscopy were used determine framework Si/Al ratio, ...

Propylene is an important raw material and extensively used in the petrochemical industry. There has been a continuously growing demand for propylene in recent years around the world1–3. The majority of propylene is produced as a byproduct from processes such as steam cracking of naphtha and fluid catalytic cracking (FCC)4,5. Additional sources of propylene included dehydrogenation of propane, ...
