Fresh Hydrilla verticillata (HV) and air-dried HV were chosen to be deoxy-liquefied in an airtight vessel reactor for high calorific fuel (HCF) production. The influence of temperature (250-450C), residence time (4-30 min), catalyst content (0.1-5 wt.%) on the yields and compositions of HCFs were investigated. Results showed that the HCFs obtained at 350C with residence time of 15 min possessed the highest HHVs (>44.06 MJ/kg) and lowest oxygen contents (<3.46 wt.%). The HCF contained benzenes, phenols, and long-chain alkanes as main components, with small proportion of non-phenolic oxy-compounds and nitro-compounds. Preliminary analysis of mechanisms indicated that high temperature or long residence time leaded to a deeper cracking of chemical bonds, which was less affected by the addition of catalyst. Experiments also suggested fresh HV rather than air-dried HV were more suitable for preparing high-quality HCF with highest yield of 18.05 wt.%. So, for water plants containing large amounts of water, deoxy-liquefaction under fresh state would be a better choice which could save a lot of energy and time consumed during drying process. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

This paper reports our investigation of the catalytic hydrothermal liquefaction (HTL) of microalgae spirulina to bio-oil. Palladium-based catalysts Pd/HZSM-5@meso-SiO2 (Pd/HZSM-5@MS) and Pd/HZSM-5 were synthesized. X-ray diffraction analysis, scanning electron microscopy, and transmission electron microscopy were used to characterize the catalysts that were applied to the HTL of algae in the presence of formic acid. Elemental analysis and gas chromatography?mass spectrometry were used to analyze the resulting bio-oil. The characterizations indicated that the Pd/HZSM-5@MS-catalyzed HTL had a high bio-oil yield of 37.30% and a low coke yield of 8.56%, and that the obtained bio-oil contained no acids. Furthermore, this study suggests that Pd/HZSM-5 promoted hydrodenitrogenation of the bio-oil and that Pd/HZMS-5@MS promoted hydrodeoxygenation of the bio-oil. Catalyst recycling and the performance of the recycled catalyst were also investigated and discussed.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Application of 52065-78-8, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 52065-78-8, in my other articles.

Hydrothermal processing of microalgae using alkali and organic acids

Aquatic organisms such as microalgae have been identified as a potential source of third generation biofuels due to their fast growth rate, ability to sequester CO2 and their potential for producing lipids. Conversion by hydrothermal liquefaction is ideally suited to high moisture content feedstocks such as microalgae and involves the processing of biomass in hot compressed water with or without the presence of a catalyst. This study aims to investigate the conditions for producing high quality, low molecular weight bio-crude from microalgae and cyanobacteria containing low lipid contents including Chlorella vulgaris and Spirulina. Liquefaction experiments have been performed in a high pressure batch reactor at 300 C and 350 C. The influence of process variables such as temperature and catalyst type has been studied. Catalysts employed include the alkali, potassium hydroxide and sodium carbonate and the organic acids, acetic acid and formic acid. Liquefaction yields have been determined and the bio-crude has been analysed for CHNOS content and calorific value. The bio-crude has been analysed by GC/MS to examine composition and thermal gravimetric analysis (TGA) to estimate its boiling point range. The aqueous fraction has been analysed for typical cations and anions by ion exchange chromatography and for total organic carbon (TOC). The yields of bio-crude are higher using an organic acid catalyst, have a lower boiling point and improved flow properties. The bio-crude contains a carbon content of typically 70-75% and an oxygen content of 10-16%. The nitrogen content in the bio-crude typically ranges from 4% to 6%. The higher heating values (HHV) range from 33.4 to 39.9 MJ kg-1. Analysis by GC/MS indicates that the bio-crude contains aromatic hydrocarbons, nitrogen heterocycles and long chain fatty acids and alcohols. A nitrogen balance indicates that a large proportion of the fuel nitrogen (up to 50%) is transferred to the aqueous phase in the form of ammonium. The remainder is distributed between the bio-crude and the gaseous phase the latter containing HCN, NH3 and N2O depending upon catalyst conditions. The addition of organic acids results in a reduction of nitrogen in the aqueous phase and a corresponding increase of NH3 and HCN in the gas phase. The addition of organic acids has a beneficial effect on the yield and boiling point distribution of the bio-crude produced.
