The fluid catalytic cracking (FCC) process is an alternative olefin production technology, with lower CO2 emission and higher energy-saving. This used for by almost 60% of the global feedstocks. Different parameters including operating conditions, feedstock properties, type catalyst can strongly affect activity product distribution. FCC catalysts contain zeolite as active component, a matrix, b...

The overall performance of a catalyst particle strongly depends on the ability of mass transport through its pore space. Characterizing the three-dimensional structure of the macro- and mesopore space of a catalyst particle and establishing a correlation with transport efficiency is an essential step toward designing highly effective catalyst particles. In this work, a generally applicable work...

This contribution is based on the monograph entitled “Recent Advances in Thermochemical Conversion of Biomass”, covering both general items as well as the primary processes, like fast pyrolysis, gasification, hydrothermal liquefaction, carbonization and secondary processes, like co-processing of bio-oil in fluidized catalytic cracking (FCC), Fischer-Tropsch synthesis and valorization of lignin ...

Reduction of greenhouse gas (GHG) emissions for mitigating climate changes is globally necessary. As a major GHG emitter, refinery sector responsible 14.1% China’s CO 2 emission in 2019. The flue associated with petroleum refining has high content, presenting potentials methanol and electricity co-production when the methane hydrogen dry are considered. To unlock green opportunity refineries, t...

The efficiency of Commercial FCC catalysts (low, medium and high activities) was evaluated by the catalytic cracking process of combined feeds of polypropylene (PP) and vaseline, using a microactivity test unit (M.A.T.) for the production of fuel fractions (gasoline, diesel and residue). The PP/vaseline loads, at 2.0% and 4.0% wt, were processed under refinery conditions (load/catalyst ratio an...
