There is still considerable controversy surrounding the mechanisms, thermodynamics, and kinetics of heavy oil aquathermolysis pyrolysis processes. The present paper aims to widen our knowledge about effect iron tallates on Cuban oil. obtained SARA (S: saturates, A: aromatics, R: resins, asphaltenes) analysis has shown a significant increase in light hydrocarbon content during aquathermolysis. M...

Fast pyrolysis bio-oils possess unfavorable physicochemical properties and poor stability, in large part, owing to the presence of carboxylic acids, which hinders their use as biofuels. Catalytic esterification offers an atom- and energy-efficient route to upgrade pyrolysis bio-oils. Propyl sulfonic acid (PrSO3 H) silicas are active for carboxylic acid esterification but suffer mass-transport l...

In this research, effect of demineralization and solvent swelling on pyrolysis kinetics was investigated. The experiments were carried out to investigate theeffects of solvent swelling with different solvents, such as THF, Pyridine and DMSO after demineralization with HCl, HNO3 and HF successively. To calculate the activation energies of lignite sample during pyrolysis, TGA analyses were perfor...

the paper introducedeffects of modified pyrolysis tar on flue gas desulfurization. this experiment selected the pyrolysis tar as the raw material, researched the effects on desulfurization performance under different modification solution, concentration, solid liquid ratio of pyrolysis tar and modified solution, calcination temperature and calcination time by 16 group orthogonal experiments. th...

The valorisation of 2,5-dimethylfuran over zeolites under catalytic fast pyrolysis conditions was analysed by on-line FTIR-MS. BTX and olefins correlate decrease with time on stream, whereas the isomerisation increases.

Catalytic upgrading of fast pyrolysis bio-oil from two different types lignocellulosic biomass was conducted using an H-ZSM-5 catalyst at temperatures. A fixed-bed reactor has been used to perform in situ catalytic experiments temperatures 673, 773, and 873 K, where the (H-ZSM-5) mixed with wood chips or lignin, processes have performed simultaneously. The fractionation method employed determin...

Owing to its low cost and large availability, lignocellulosic biomass is being studied worldwide as a feedstock for renewable liquid biofuels. Lignocellulosic biomass is not currently used as a liquid fuel because economical processes for its conversion have not yet been developed. Currently, there are several routes being studied to convert solid biomass into a liquid fuel which involve multip...

Ceria thin films deposited by spray pyrolysis show a strong preferential 〈200〉 orientation after annealing corresponding to the {100} facet of high catalytic activity. This texture correlates with an unusually blue shift Raman F 2g peak.

Pyrolysis vapor upgrading can improve the stability of pyrolysis liquids to facilitate storage, transport, and drop in use as fuels chemical feedstocks existing refining infrastructure. This study investigates a low cost iron based catalyst for mild in-situ fast vapors increase liquid. Iron-doped montmorillonite K10 catalysts were characterized by ICP-OES, BET porosimetry, XRD, XPS, NH3-TPD. Th...
