A recent study has found one means of complementing agricultural production with biodiversity protection by growing seeded ryegrass for silage. The seeds effectively feed many birds, such as the yellowhammer and reed bunting, throughout the winter, and the grass can still be cost-effectively used for silage if it is harvested at the right time.

Growing demand for biorenewable chemicals could lead to conflicts with food production and unwanted environmental impacts. Against this context, this study investigated different types of feedstock and conversion technologies. The authors recommend use of only non-edible feedstock alongside green and carbon neutral conversion technologies, such as algal fermentation.

Methods are provided for refining natural oil feedstocks and producing dibasic esters and/or dibasic acids. The methods comprise reacting a terminal olefin with an internal olefin in the presence of a metathesis catalyst to form a dibasic ester and/or dibasic acid. In certain embodiments, the olefin esters are formed by reacting the feedstock in the presence of a metathesis catalyst under conditions sufficient to form a metathesized product comprising olefins and esters, separating the olefins from the esters in the metathesized product, and transesterifying the esters in the presence of an alcohol to form a transesterified product having olefin esters.

In various aspects, the invention provides for processing a hydrocarbon feed having hydrocarbon and emulsified aqueous components demulsifying into hydrocarbon and aqueous phases over an initial demulsification time, with an active agent to form a treated feed. The active agent has an active agent solubility in the hydrocarbon component and in the aqueous component, the aqueous component has an aqueous component solubility in the hydrocarbon component. The active agent solubility in the hydrocarbon component is greater than the aqueous component solubility in the hydrocarbon component. The active agent solubility in the aqueous component is greater than the active agent solubility in the hydrocarbon component. The active agent solubility in the aqueous component is greater than the active agent solubility in the hydrocarbon component. A treated demulsified hydrocarbon phase separates from the active agent and the aqueous component in a modified demulsification time that is shorter than the initial demulsification time.

The cellulosic feedstock is introduced into a longitudinally extending enclosed volume, and conveyed longitudinally through the enclosed volume while being mixed.

A hydrocarbon conversion process comprises contacting a renewable feedstock under hydroprocessing conditions with a bulk catalyst to form oleochemicals such as fatty alcohols, esters, and normal paraffins. Advantageously, the reaction conditions can be selected to directly convert the renewable feedstock to the desired product(s).

Wood particles having fibers aligned in a grain, wherein: the wood particles are characterized by a length dimension (L) aligned substantially parallel to the grain, a width dimension (W) normal to L and aligned cross grain, and a height dimension (H) normal to W and L; the L×H dimensions define two side surfaces characterized by substantially intact longitudinally arrayed fibers; the W×H dimensions define two cross-grain end surfaces characterized individually as aligned either normal to the grain or oblique to the grain; the L×W dimensions define two substantially parallel top and bottom surfaces; and, a majority of the W×H surfaces in the mixture of wood particles have end checking.

The inventive technology includes methods and apparatus for the generation and application of segregated catalytic additives for the pre-combustion treatment of carbonaceous fuel and/or feedstocks. The application of such segregated additives results in the reduction of environmentally harmful emissions during combustion as well as gasification processes. Specifically, pre-combustion treatment of carbonaceous materials with the inventive additives results in the reduction of NOx and/or mercury emissions by least 20% and 40% respectively.

This invention presents a versatile and continuous drying technology that utilizes controlled heat combined with forced air supply for drying a feedstock. The dryer virtually divided top-down into different zones, each having definite heated air distribution rate to secure desired condition for drying of the feedstock. The heat source of the dryer is waste heat, either provided by the feedstock itself through exothermic heat generated by the feedstock or reclaimed waste heat or solar heat. The discharge system of the dryer is a fail-safe discharge system, which ensures equal residence time for the feedstock through all the zones. The synergic interaction of all these components along with recycling the heat through an efficient use of heat exchangers, optimized control of airflow rate and feedstock resident time, purifying the exhaust air and condensing the outlet vapor empowers the technology to function with minimum energy, minimum processing time, minimum environmental foot-print, minimum cost and with minimum operational cost.

A process and system is disclosed for optimizing a key parameter of a biomass feedstock that enhances bio-oil production. The process and system involves optimizing the values of the key parameter in multiple biomass feedstocks by regulating their feed rates and blending those feedstocks to produce a cumulative biomass feedstock with an optimal value for the key parameter. The key parameter in the biomass feedstocks is measured and the feed rates of the multiple biomass feedstocks are adjusted in order to produce a cumulative biomass feedstock exhibiting optimal values for the desired key parameter. The key parameters can include compositional properties, such as lignin content or mineral content, and/or fluidization properties of the biomass materials, such as density, particle cohesion force, or particle size.
