TL;DR: In this article, the effects of temperature and space time on the transformation over a HZSM-5 zeolite catalyst of several model components of the liquid product obtained by the flash pyrolysis of vegetable biomass (1-propanol, 2-polyphenol, phenol, and 2-methoxyphenol) have been studied.

TL;DR: In this article, the catalytic transformation over a HZSM-5 zeolite of key components of the liquid product obtained by the flash pyrolysis of biomass, namely, acetaldehyde, ketones (acetone and butanone), and acetic acid, has been studied, and great differences in reactivity and degradation to coke have been found.

TL;DR: In this article, the operation regimes of spouting and of jet spouting have been delimited in the bed expansion in conical contactors, and the ranges of the geometric factors of the contactor-particle system and of the gas velocity for stable operation in both regimes have been determined by experiments in a pilot plant using different solids.

TL;DR: In this article, the effect of the zeolite structure (HZSM-5, Hβ and HY) on coke deposition during the cracking of high-density polyethylene has been studied by combining the results of multiple spectroscopic and analytical techniques: FTIR, Raman, UV-vis, 13 C NMR and coke extraction.

TL;DR: In this article, the effect of operating conditions (temperature, space time, and time-on-stream) on catalytic transformation of the aqueous fraction of the biomass pyrolysis oil obtained in a conical spouted bed reactor under atmospheric pressure was studied.
