This utility model provides a zero-carbon emission heating boiler system, including: an inner auger tube, a gasifier, a waste heat boiler, a denitrification cylinder, and a feed auger. The inner auger tube is equipped with a set of feed augers for introducing raw materials such as rice husks and wood chips. A set of gasifiers for gasifying the raw materials is located on the right side of the feed augers. Three sets of gasifiers are arranged side by side. Compared with the prior art, this utility model has the following beneficial effects: the raw materials such as rice husks and wood chips are burned and gasified through the gasifiers, and the high-temperature flue gas generated by combustion is recovered. At the same time, the biochar generated by burning the raw materials such as rice husks and wood chips can be collected through a storage tank and used as renewable fuel.

A fuel composition comprising a base fuel and an additive mixture, wherein the base fuel comprises a renewable fuel component, and wherein the additive mixture comprises: (i) a first additive comprising a long-chain carboxylic acid polyamine; and (ii) a second additive comprising an ionic or nonionic oil-soluble polar organic nitrogen-containing compound having a single nitrogen atom per molecule; wherein the weight ratio of the first additive to the second additive is in the range of 6:1 to 2:1. The additive mixture is capable of improving the low-temperature flow properties (cloud point and CFPP) of the renewable fuel component.

Disclosed are systems, methods, and compositions for producing renewable alcohols, conversion of C1-C5 alcohols to a mixture of C2-C7 olefins to generate stream for recycle to the alcohol conversion step to create or separate oligomerization conversion to generate a predominantly C4+ stream, oligomerizing stream into fuel range olefins to create a stream, separating stream into fractions appropriate for use as gasoline, jet, and diesel fuels. The disclosure also provides systems, methods, and compositions of bio-based ethanol that can be converted to ethylene and subsequently to mixtures of C3-C8 olefins in a single-step.

The application pertains to an alternating hydroprocessing process comprising reacting a lipid or a mixture of lipid and petroleum feedstock with hydrogen in the presence of a catalyst in a vessel under conditions suitable to form a renewable hydrocarbonaceous product. The formed renewable product is removed from the vessel. A petroleum feedstock is then reacted with hydrogen in the presence of the catalyst in the vessel under conditions suitable to form a hydrocracked fossil product.

This invention discloses a renewable fuel cell, comprising an oxygen electrode flow field plate, an oxygen electrode diffusion layer, a membrane electrode, a hydrogen electrode diffusion layer, and a hydrogen electrode flow field plate stacked sequentially. The oxygen electrode flow field plate includes a base plate with a central mounting cavity, a front inlet cavity, and a rear outlet cavity. The central mounting cavity of the base plate has several rows of corrugated plates arranged evenly from top to bottom to form a flow field reaction zone. The front inlet cavity has several rows of inlet fluid distribution units arranged evenly from top to bottom to form a fluid distribution inlet zone. The rear outlet cavity has several rows of outlet fluid distribution units arranged evenly from top to bottom to form a fluid distribution outlet zone. In FC (Fuel Cell) operating mode, this invention ensures the diffusion capacity of the reactant gas while improving mass transfer capacity throughout the gas transport process. This reduces gas starvation caused by reactant gas blockage and flooding caused by the accumulation of generated water, thereby increasing the performance of the renewable fuel cell.

Provided is a process for optimizing throughput and flash during the hydroconversion of circular and renewable feed stocks into renewable fuel comprising the use of a slurry reactor. The present process uses high pressure operation of a vaporization stage in combination with the use of low-pressure stripping segments. The inclusion of low-pressure stripping segments allows the reactor to operate at high pressure, reducing CAPEX and OPEX, without the associated issues with flash and throughput commonly observed.
