This study investigated co-liquefaction of microalgae (Chlorella pyrenoidosa, CP) and lignocellulosic biomass (Rice husk, RH) in subcritical water for bio-oil production. The effects of liquefaction temperature (200-350°C), residence time (10-90min), solid concentration (10-30wt.%) and mass ratio of CP/RH on product distribution were investigated. The results showed that the highest yield of bi...

Introduction The reciprocating biomass conversion reactor (RBCR) is a novel means of converting biomass to bio-oil. The RBCR is a repurposed highcompression 4-stroke internal combustion engine into which a fluidizing gas and a small volume fraction of pulverized biomass are introduced, and the crankshaft is cycled by an external energy source to supply the process heat for thermo-chemical conve...

Fast pyrolysis oils are one source of renewable liquid fuels, which could be used as green fuels in a sustainable manner. The ASTM D664 method used to determine the acidic constituents in petroleum products, lubricants, and biodiesel requires mixtures of isopropyl alcohol (IPA) and toluene as solvent. The ASTM method also uses large quantities of solvents for the total acid number (TAN) determi...

In order to investigate the effect of different levels of nitrogen and bio-fertilizers on yield of canola plants in Qazvin, Iran, a split-plot design was conducted on the base of randomized complete block design with four replications. Treatments included 3 levels of nitrogen (0, 75 and 150 kg ha-1) and bio-fertilizers on four levels (no inoculation, Azotobacter, Azospirillum and a combination ...

Background The production of fuels and chemicals from renewable resources is increasingly important due to the environmental concern and depletion of fossil fuel. Despite the fast technical development in the production of aviation fuels, there are still several shortcomings such as a high cost of raw materials, a low yield of aviation fuels, and poor process techno-economic consideration. In r...

A pot experiment was conducted to determine the effect of compost and bio-fertilizers on the growth, yield and oil constituents of marjoram (Majorana hortensis L.). Forty five days old seedling were transplanted in soil treated with 15 and 30% aqueous extracts of compost and/or biofertilizers (mixture of Azospirillum brasilienses, Azotobacter chroococcum, Bacillus polymyxa & B. circulans) in ad...

The aim of the research work was to isolate a novel bio material from the seeds of Buchanania Lanzan and to evaluate its bio stabilizing ability by various formulating various zidovudine micro emulsions using sunflower oil as oil phase and bio material as bio emulsifier. The bio material was isolated from the seeds of Buchanania Lanzan by simplified economical method. Three different zidovudine...

A fluidized bed reactor that is operating in the bubbling regime has been developed for the conversion of bio-oils to syngas.The reactor consists of a 7.6 cm I.D. (or internal diameter) bed, with an expanded freeboard. The volume of the reactor can be adjusted to vary the gas residence time. This reactor has been used to carry out either thermal or catalytic cracking for reforming bio-oils.A ga...
