A method for controlling a feedstock blend is described, comprising the steps of: measuring a corrosion of a pipe in a fuel processing facility with a sensor; setting a maximum sulfur content in the feedstock blend based on the corrosion; measuring a build-up of material in the pipe with the sensor; establishing a maximum viscosity of the feedstock blend based on output of the sensor; blending, to form the feedstock blend, a first feedstock and a second feedstock to fulfill both the maximum sulfur content and the maximum viscosity; and passing the feedstock blend through the first pipe.

Multi-carbon compounds such as ethanol, n-butanol, sec-butanol, isobutanol, tert-butanol, fatty (or aliphatic long chain) alcohols, fatty acid methyl esters, 2,3-butanediol and the like, are important industrial commodity chemicals with a variety of applications. The present invention provides metabolically engineered host microorganisms which metabolize methane (CH4) as their sole carbon source to produce multi-carbon compounds for use in fuels (e.g., bio-fuel, bio-diesel) and bio-based chemicals. Furthermore, use of the metabolically engineered host microorganisms of the invention (which utilize methane as the sole carbon source) mitigate current industry practices and methods of producing multi-carbon compounds from petroleum or petroleum-derived feedstocks, and ameliorate much of the ongoing depletion of arable food source “farmland” currently being diverted to grow bio-fuel feedstocks, and as such, improve the environmental footprint of future bio-fuel, bio-diesel and bio-based chemical compositions.

The utility model discloses a feed mechanism of biofuel granulator, including feed hopper, discharge hammer shaker mechanism, external connection mechanism and clamping auxiliary mechanism, discharge hammer shaker mechanism includes hydraulic cylinder and rotary frame, external connection mechanism includes clamping pipe and clamping rod, the clamping auxiliary mechanism includes outer swivel and longitudinal shift ring, and the outer swivel and the longitudinal shift ring are connected through the clamping pipe and the clamping rod. The discharging hammer shaking mechanism drives a rotating frame through a hydraulic cylinder, so that an elastic plate and a hammered plate are in intermittent contact to generate periodic vibration impact, a vibration mechanism effectively prevents a biofuel raw material from caking and adhering in a feeding hopper and ensures smooth flowing of the material, and an external connection mechanism realizes rapid and reliable connection between the feeding mechanism and external equipment. The clamping pipe is in meshing transmission with the clamping tooth plate through the inner tooth ring, so that the clamping tooth plate can rotationally stretch into or be away from the clamping groove of the clamping rod, and plug-pull type connection is achieved.

This invention discloses a process for extracting oils from furfural wastewater to prepare bio-aviation fuel feedstock, applicable to the high-value recovery of trace oils from the primary distillation column wastewater during furfural production. The process includes steps such as feedstock hydrolysis, gas condensation, cooling and stratification of the wastewater oils at the bottom of the column, secondary air flotation oil extraction, isothermal thermal devolvation for impurity removal, microfiltration, saponification reaction, alcohol extraction, and vacuum distillation. By constructing a four-stage synergistic removal mechanism of thermal devolvation + saponification phase separation + alcohol extraction + vacuum distillation, unsaponifiable matter, insoluble substances, and water in the oils are effectively separated to obtain high-purity fatty acid methyl ester products, which can be directly used as bio-aviation fuel feedstock. This method is mild, energy-efficient, non-toxic, and environmentally friendly, avoiding secondary pollution caused by traditional extraction processes. It is both economical and practical, effectively extending the operating cycle of the wastewater evaporator, improving system stability and economic value, and providing a new path for the resource utilization of furfural wastewater.
