The invention relates to a process for producing dimethyl ether (DME). The invention provides that a first and a second reaction zone in which catalyst fills are arranged between two adjacent pillow plates and are traversable by the respective input gas are arranged in a common synthesis reactor. The pillow plates are traversable by a fluid cooling medium. The DME-containing product gas stream exiting the synthesis reactor is resolved into a DME end product stream, a gas byproduct stream containing unconverted carbon oxides and hydrogen, a methanol byproduct stream and a wastewater stream. The gas byproduct stream is at least partially returned to the reactor inflow to increase the altogether achieved DME yield.

The purpose of the present invention is to enable the production of 3,5-dihydroxy-4-methoxybenzyl alcohol (DHMBA), which is a novel antioxidant, from the shellfish meat of a filter-feeding bivalve other than oyster by extracting the shellfish meat of the filter-feeding bivalve under heating or pressurizing. The method according to the present invention is characterized by comprising adding the shellfish meat of a filter-feeding bivalve other than oyster to an extraction liquid and heating the extraction liquid to thereby produce 3,5-dihydroxy-4-methoxybenzyl alcohol from the thus heated shellfish meat liquid of the bivalve.

Disclosed is a method that reforms flare gas or other raw natural gas source, using air without steam, to directly produce dimethyl ether (DME), a direct diesel substitute. The method first reforms an air-natural gas mixture at ambient atmospheric pressures, and then compresses the resulting CO-hydrogen-nitrogen gas mixture to 100-2,000 psi, and feeds it through a combined reactor which reacts the gas mixture directly into DME. The nitrogen is returned to the atmosphere. DME is an excellent diesel fuel, and can be used to displace significantly costlier and dirtier petroleum-based diesel fuel, while solving a critical problem with flaring or other wasted natural gas. For example, the roughly 120 billion cubic feet per year that was flared in North Dakota in 2014 could be converted into over 3 million tons of DME using the disclosed method.
