  • Publication number: 20230313968
    Abstract: A lens plate has an array of lenslets. A first surface comprises a plurality of individual cells, each cell delimiting one side of a respective lenslet of the array. A second opposite surface comprises a set of grooves, each groove delimiting a second, opposite side, of a sub-array of the lenslets of the array of lenslets. The array of lenslets is a circular array comprising a plurality of concentric rings. Each ring comprises a plurality of straight segments, and each segment comprises multiple said lenslets arranged in a row. The lens plate design thus combines grooves on one side which cover multiple lenslets and a cellular lens structure on the opposite side.

  • Patent number: 11198820
    Abstract: Provided is a conversion process for an organic oil, relating to the field of biomass utilization, energy and chemical industry. The conversion process is carried out in presence of an aqueous slurry and a catalyst selected from the group consisting of an iron oxide compound, a waste agent resulting from use of an iron oxide compound as desulfurizer, and a regeneration product of the waste agent, under a controlled molar ratio of iron element to sulfur element. It is found that free radical condensation polymerization of organic oil during cracking process can be blocked effectively by using carbonylation, and hydrogenation is achieved with active hydrogen produced from the conversion of CO and water. In the conversion process, organic material, especially biomass solid, can be directly converted without dehydration, and water can be additionally added to the biomass liquid or the mineral oil.
