PREPARATION AND APPLICATION METHOD OF BIO-BASED LONG-CHAIN ALCOHOL-ETHER OXYGENATE DIESEL ADDITIVES
20220106244 · 2022-04-07 · ·

A biomass-based long-chain alcohol ether oxygenated additive and a preparation method and application thereof are disclosed. The additive used agricultural and forestry wastes as raw materials, and has a general chemical formula of R—(O—C.sub.1-3).sub.n—R—OH. The preparation method includes the following steps: step 1, performing drying pretreatment on biomass raw materials, performing rapid pyrolysis under an inert atmosphere to obtain a pyrolysis product containing water, gases, water-phase bio-oil and oil-phase bio-oil, separating out the water-phase bio-oil and performing catalytic hydrogenation on the water-phase bio-oil to obtain polyols; step 2, performing catalytic dehydration on the polyols obtained in step 1 under a basic catalyst system to obtain epoxyalkane; and step 3, making the epoxyalkane obtained in step 2 and methanol undergo a reaction under a molecular sieve catalyst and removing the solid catalyst by separation to obtain the long-chain alcohol ether oxygenated additive.

Efficient procedure and system to process solid organic waste

The techniques introduced here include a system and method for efficiently, and in some embodiments automatically, processing solid organic waste. In both the method and the system the solid organic waste is injected into a rotating, thermally isolable, container with internal sensors that help in keeping humidity and temperature within given parameters, before the resulting dried solid organic waste is sent to a pyrolysis chamber and its exhausts are sent to filter. In some embodiments, inert material in the form of dried solid organic waste is left in the container in order to make the process even more efficient and system and process are made automatic and remotely controllable through the use of software automation and a web of internal and external sensors.

HIGH-CARBON BIOGENIC REAGENTS AND USES THEREOF
20210395630 · 2021-12-23 ·

This invention provides processes and systems for converting biomass into high-carbon biogenic reagents that are suitable for a variety of commercial applications. Some embodiments employ pyrolysis in the presence of an inert gas to generate hot pyrolyzed solids, condensable vapors, and non-condensable gases, followed by separation of vapors and gases, and cooling of the hot pyrolyzed solids in the presence of the inert gas. Additives may be introduced during processing or combined with the reagent, or both. The biogenic reagent may include at least 70 wt %, 80 wt %, 90 wt %, 95 wt %, or more total carbon on a dry basis. The biogenic reagent may have an energy content of at least 12,000 Btu/lb, 13,000 Btu/lb, 14,000 Btu/lb, or 14,500 Btu/lb on a dry basis. The biogenic reagent may be formed into fine powders, or structural objects. The structural objects may have a structure and/or strength that derive from the feedstock, heat rate, and additives.
