This study presents a detailed analysis of the catalytic de-oxygenation of the liquid and gaseous pyrolytic products of two biomasses (beech wood and flax shives) using different catalysts (commercial HZSM-5 and H-Y,and lab-synthesised Fe-HZSM-5,Fe-H-Y,Pt/Al2O3 and CoMo/Al2O3). The experiments were all conducted in a semi-batch reactor under the same operating conditions for all feed materials. BET specific surface area,BJH pore size distribution and FT-IR technologies have been used to characterise the catalysts,while gas chromatography-mass spectrometry (GC-MS),flame ionisation detection (GC-FID) and thermal conductivity detection (GC-TCD) were used to examine the liquid and gaseous pyrolytic products. It was firstly seen that at higher catalyst-to-biomass ratios of 4∶1,de-oxygenation efficiency did not experience any further significant improvement. FeHZSM-5 was deemed to be the most efficient of the catalysts utilised as it helped reach the lowest oxygen contents in the bio-oils samples and the second best was HZSM-5. It was also found that HZSM-5 and H-Y tended to privilege the decarbonylation route(production of CO),whilst their iron-modified counterparts favoured the decarboxylation one (production of CO2) for both biomasses studied. It was then seen that the major bio-oil components (carboxylic acids) underwent almost complete conversion under catalytic treatment to produce mostly unoxygenated aromatic compounds,phenols and gases like CO and CO2. Finally,phenols were seen to be the family most significantly formed from the actions of all catalysts.

Background The optimal management of ipsilateral extracranial internal carotid artery(ICA)stenosis during endovascular treatment(EVT)is *** compared the outcomes of two different strategies:EVT with vs without carotid artery stenting(CAS).Methods In this observational study,we included patients who had an acute ischaemic stroke undergoing EVT and a concomitant ipsilateral extracranial ICA stenosis of≥50%or occlusion of presumed atherosclerotic origin,from the Dutch Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands(MR CLEAN)Registry(2014-2017).The primary endpoint was a good functional outcome at 90 days,defined as a modified Rankin Scale score≤*** endpoints were successful intracranial reperfusion,new clot in a different vascular territory,symptomatic intracranial haemorrhage,recurrent ischaemic stroke and any serious adverse *** Of the 433 included patients,169(39%)underwent EVT with *** 123/168(73%)patients,CAS was performed before intracranial *** 42/224(19%)patients who underwent EVT without CAS,a deferred carotid endarterectomy or CAS was *** with and without CAS were associated with similar proportions of good functional outcome(47%vs 42%,respectively;adjusted OR(aOR),0.90;95%CI,0.50 to 1.62).There were no major differences between the groups in any of the secondary endpoints,except for the increased odds of a new clot in a different vascular territory in the EVT with CAS group(aOR,2.96;95%CI,1.07 to 8.21).Conclusions Functional outcomes were comparable after EVT with and without *** during EVT might be a feasible option to treat the extracranial ICA stenosis but randomised studies are warranted to prove non-inferiority or superiority.
