A water-based extraction process for extracting bitumen from mined oil is provided comprising providing a water-based mixture containing bitumen; and introducing nanobubbles to the mixture to attach to bitumen and, thereby, extract the bitumen from the water-based mixture, wherein a nanobubble has a diameter of less than 5,000 nm.

The present disclosure provides a process for upgrading solid biomass feedstocks into more useable products. The process includes introducing a solid biomass feedstock, a renewable liquid carrier, a slurry hydrocracking catalyst to a slurry hydrocracking zone in the presence of hydrogen and under slurry hydrocracking conditions to produce a slurry hydrocracking effluent comprising lighter hydrocarbonaceous products.

The invention is directed to a process to continuously prepare a gas oil product from carbonaceous particles of a biomass source comprising the following steps. (a) contacting carbonaceous particles with a hydrogen comprising gas in a fluidised bed reactor in the absence of oxygen and in the absence of a catalyst, at an average solids residence time of between (20) and (120) seconds and at thermal conversion conditions to obtain a gaseous mixture comprising of hydrocarbons and char particles. (b) discharging the char particles and the gaseous mixture separately from the fluidised bed reactor. And (c) isolating from the gaseous mixture a gas oil product by means of distillation.

A method for treating effluent from hydrothermal liquification of feedstock that contains plastic oil, pyrolysis oil, synthetic oil or hydrocarbons distillates in a plastic recycle process using supercritical water as a reaction medium into a finished liquid hydrocarbon fuel by removing impurities such as i.e. silicon, chlorides, metals, heteroatoms, etc., in a pre-treatment zone and may be passed into a feed drum or a continuous mixed settler vessel. The feed is introduced into a hydrogen atmosphere reactor. The reactor effluent is passed to a separator for extracting product mixture by addition of make-up or recycled hydrogen to the separator. The overhead product mixture is water washed to remove sour water or salt. The separator effluent is passed to a distillation section for extracting a liquid fuel product stream. A portion of the hydro processing product stream may be recycled to the feed drum or the continuous mixed settler vessel, which reduces concentration of diolefins.

A biofuel includes a mixture of a gasoil generated from hydropyrolysis and hydroconversion of a solid biomass containing lignocellulose. The gasoil has a cetane index less than 46. The biofuel also includes a hydroprocessed ester fatty acid (HEFA) generated from hydrotreating a renewable resource having fats and oils. A cetane index of the biofuel is greater than 46.

The present disclosure generally relates to compositions and methods of simultaneously making two unique biointermediates from a single lignocellulosic biomass feedstock, including a hydrophobic biohydrocarbon and a water insoluble hydrophilic cellulosic biopolymer for use in the production of renewable fuels, chemicals, and other carbon neutral materials commonly derived from petroleum and other fossil resources.

The use of renewable energy to reduce fossil fuel consumption is a key strategy to mitigate pollution and climate change, resulting in the growing demand for new sources. Fast-growing proprietary cyanobacterial strains of Fremyella diplosiphon with an average life cycle of 7-10 days, and a proven capacity to generate lipids for biofuel production were studied. We investigated the growth and photosynthetic pigmentation of a cyanobacterial strain (SF33) in both greenhouse and outdoor bioreactors and produced biocrude via hydrothermal liquefaction. The cultivation of F. diplosiphon did not significantly differ under suboptimal conditions (p<0.05), including in outdoor bioreactors with growth differences of less than 0.04 (p=0.035) among various batches. An analysis of the biocrude's components revealed the presence of fatty acid biodiesel precursors such as palmitic acid and behenic acid, and alkanes such as hexadecane and heptadecane, used as biofuel additives. In addition, the quantification of value-added photosynthetic pigments revealed chlorophyll a and phycocyanin concentrations of 0.00115.8310.sup.5 g/L and 7.0510.067 g/g chlorophyll a. Our results suggest the potential of F. diplosiphon as a robust species that can grow at varying temperatures ranging from 13 C. to 32 C., while producing compounds for applications ranging from biofuel to nutritional supplements. This paves the way for production-level scale-up and processing of F. diplosiphon-derived biofuels and marketable bioproducts. Fuel produced using this technology will be eco-friendly and cost-effective and will make full use of the geographical location of regions with access to brackish waters.
