Abstract: A process for converting a cellulosic feedstock to chemical compound, such as an alcohol, or mixture of chemical compounds, wherein one or more process streams can be used in one or more of the other process steps.

Abstract: A method of producing renewable material comprising (a) converting biologically a hemicellulose-derived material to form a first mixture comprising a first renewable material, and (b) convening a substantial amount of a material comprising cellulose and lignin in the presence of at least a portion of the first mixture to form a second mixture comprising second renewable material.

Abstract: This invention relates to a process, a plant, and butanol made of or derived from lignocellulosic feedstock. The process includes the step of depolymerizing lignocellulosic material to form pentose and a remainder. The process also includes the step of converting the pentose to butanol material and using the remainder for generation of power or further downstream conversion.

Abstract: This invention relates to a process and a plant for biofuel production, such as with biogasoline and/or biodiesel. The process includes the step of depolymerizing lignocellulosic material to form pentose and a remainder. The process also includes the step of converting the pentose to a biofuel material and using the remainder for generation of power or further downstream conversion.

Abstract: A modulator for resonant DC link and other power converters is provided having superior performance and general applicability to multi-phase converters. The modulator includes three major components: (1) a multi-input, multi-output linear system, (2) a quantizer, and (3) a latch. The linear system receives multiple reference signal waveforms and multiple feedback signal waveforms representative of the modulator output as input signals and produces multiple linear output signals derived from the difference between the reference and feedback waveforms as outputs. The linear system is preferably a second order system. The quantizer assigns the continuous output of the linear system to one of a finite set of discrete output vectors. The output of the quantizer is latched at a sampling rate synchronized with the times of zero voltage or current on the DC bus of the converter.
